Pantanal 25 Vega - report about a regatta

We have been publishing regularly stories about achievements in the racing course of Pantanal 25 boats, a design for amateur or professional construction primarily intended to be an easy to be trailed drop-keel camping boat. Dark Ice, the first Pantanal 25 to sail, proved to be the boat to be beaten, gathering an impressive record of titles in her short career.

The Pantanal 25 interior layout is far from being as Spartan as that of a racing machine.

Other boats of the class kept confirming this speed potential, what is very assuring. Now, our friend Daniel D’Angelo, from City Bell, Buenos Aires, Argentina, the B & G’ champion in amateur boat building speed (he was the first to conclude the construction of a Samoa 28, the sparkling Sirius, even though he was far from being the first to start building one of them), is now proving to be a keen sailing racer. After completing Sirius, he loved so much the boat building hobby that he went for a second trial, to build the Pantanal 25 Vega, this one to fulfil his latest passion, sailboat racing. Read the e-mail he sent us:

After competing in several club races in the River Plate without taking advantage of my Pantanal 25 Vega potential, finally my mate Oscar and I could savour the sweet taste of being the winners.

On previous occasions we invariably missed some golden chance to do much better. The results in previous races were always below our expectations, invariably with an excuse that if so and so hadn’t happen the story would have been quite different, like...if we hadn’t missed that buoy... if we hadn’t grounded on that sand bank...we would have won the race.

It was August last Sunday that we took a decision of doing the right things to put my beloved Vega in the picture.
We arrived at the club early in the morning, being the first boat to use the travel lift with the intention of buffing the hull’s gel to give it a fresh glaze. Poor little chap!...We found an authentic Persian carpet attached to her bottom!

We sanded and cleansed her bottom exhaustively and put her straight back into the water. Next we went out for another drill of hoisting and retrieving the spinnaker, something we had never done before.

That Sunday the weather forecast announced four to seven knots winds, which proved to be correct. It was noticeable the difference the scrubbed bottom was producing. Vega glided effortlessly in an almost complete lull. What a bliss to discover we were able to manoeuvre the spi all by ourselves! It seemed so complicated when others performed the task! After an exhaustive jibe drill, we returned to the club to have lunch with the family.

The start was scheduled for three o’clock. Fifteen minutes before, we were tacking to leeward of the starting line together with the twenty-two other competitors. Since we were sailing in a breath of wind, we had to be tacking incessantly, together with the rest of the fleet, all done in absolute slow motion. Vega, with mainsail only, bore off the wind until two minutes were left. We went swaggering along the starting line and hoisted the genoa when it remained five seconds for the starting gun...crossing the line in first place!

A few days earlier I went sailing in Vega with similar conditions and on that occasion I tried to play with shifting weights to see how the boat responded to displacing the crew weight forward, aft, to lee and to windward. I noticed that the response in boat speed was stunningly sensible. Based on the data obtained, I put my learning in practice and we both moved forward and to leeward. What awesome sensation was watching the whole fleet sailing in our wake! We never had this pleasure before!

It was unbelievable the distance we were gaining from the rest of the fleet, the ones we could watch from the distance being those that chose our tack. The first mark was to windward where the river makes a slight turn. We tried to get the most to windward at each new puff of wind trying to reach the mark in the same tack. Only three boats managed to do so, Vega and the two others closer to us, the other boats having to change tacks, at least to avoid a lee shore. The two boats closer to us were a Pandora 31 and a Mitiaro 256. The Pandora was slowly getting closer to us, but when Vega hit a gust its acceleration was stunning, leaving behind at the former distance our most challenging competitor.

We rounded the buoy in first place, far ahead of Pandora.
Keeping our heads as cool as possible considering the unexpected circumstance of leading the fleet, we got ready to launch the spi, a task that, in spite of our morning drill, we didn’t manage to do so quickly as we did earlier, most probably for the jitter of leading the race. When we managed to trim it properly, Vega fired off, keeping the leading edge to the other boas, in spite of Pandora hoisting a ghostly light and of huge proportions asymmetrical spinnaker.

About half way on the reaching leg we lost our spinnaker pole topping lift, and under the pressure of the down haul alone, the pole end fitting broke. This obliged us to run for a while without the assistance of the spi, allowing Pandora to close on us.
When we managed to solve the problem with a makeshift repair, we started gaining ground again. However our temporary repair didn’t stand the load and the pole broke again. Once more our chaser got on our heels overtaking us before we rounded the second mark. In a last effort, we made a second attempt in fixing the end fitting, and no sooner we managed to run the spi fully trimmed, we got the first place one more time, but for a short time only. Taking advantage of their gigantic asymmetrical, and of being fully assisted by a complete crew, they managed to pass us again. Then the wind shifted and in short time we were beating with the wind on the nose. Almost simultaneously both boats retrieved their running sails and hoisted their genoas. Under-crewed, we took a little longer to accomplish the manoeuvre, costing us the first position at the lee mark.

The last leg was a beam reach, and even so we made some progress on them, we didn’t manage to cross the line as blue ribbon. That was the only goal we missed. We knew we had won the race by a large margin in the correct time, but this still had to be confirmed.

To be the first boat to haul out was a new feeling for us too. However the highlight of the day was receiving compliments from the other crews as they reached the club.

While we waited in the club’s bar, sipping the most deserved ice-cold beer, came the confirmation that we were first over all, four minutes ahead of the second placed, a Match 30 racing machine!

Even though we must admit that our manoeuvres were lousy, we had the chance to confirm Vega’s high performance, however still requiring a lot of learning from our part to take full advantage of its full potential.
In short, it’s quite rewarding to know that we can win. Let’s see how we will be doing in the next race.

Pantanal 25 Kalahary sailing in Porto Alegre, Brazil

It is extremely rewarding for us when we are informed by a client of ours that he is fully satisfied with the boat he built. This was the case of the civil architect Carlos Zanella Fitchner, the amateur who just launched his Pantanal 25 Kalahary in Porto Alegre, State of Rio Grande do Sul, Brazil. Carlos built his boat totally unassisted with a firmness of purpose difficult to be matched by any other amateur.

Kalahary was built with a personal touch typical of architects.

Carlos, as creative architects use to do, gave a touch of personalization to the interior layout to highlight his priorities, which were undeniably turned to cruising purposes.

Since he is a skilled and dedicated craftsman, he obtained a handsome result, and Kalahary became quite a cute boat.
According to Carlos, the most important feature of the design is the drop keel system, a must for those who sail the shallow waters of the Guaíba Lake, the cruising ground of local sailors.

Kalahary inauguration is good news for the class. With the present difficulty in finding vacant places in marinas, and the consequent soaring of marina fees, the possibility of keeping the boat at home when not in use is quite alluring, and this may be the main reason for the Pantanal 25 recent success.

Carlos opted for bright, modern interior decoration giving a charming atmosphere to the ambience.
He is very proud of his boat. He published these pictures in Facebook calling Kalahary his work of art

And this is how the Pantanal 25 class is spreading its horizons. Every fortnight we are being informed about an inauguration of a boat of the class, so far with every single builder pleased with his achievement. We wish very good luck to every new owner.
The hot news is that Vera Cruz Boat Builder, from Sao Paulo, Brazil, is soon going to inaugurate a plant to produce the Pantanal 25.

Pantanal 25 Vega is launched in the River Plate

Our friend and client Daniel D’Angelo is brimming over with happiness regarding his new toy, the Pantanal 25 VEGA. If you use to follow the news in our site, you probably remember seeing the video of the boat being transported by trailer from his house, where he built her, to the club’s workshop where she would be painted.
Daniel was so anxious to see his creation sailing that he didn’t even install the windows and other finishing details. Even the sails were borrowed from the boat he had built previously, the Samoa 28 SIRIUS.
Daniel sent us an e-mail reporting the launching of the VEGA which we transcribe below:

This December 23, after lots of hard work, I finally managed to launch my Pantanal 25 VEGA. I had to endure a lingering row with the paint workers who seemed to be accomplishing an endless job. Before I lost my temper I took my boat out of the workshop with the paint job still unfinished.

So it started a frenetic race against the clock in order to be able to inaugurate her before the end of the year. Many details were missing yet and many tasks still had to be completed. To crown it all, summer arrived without lenience and the parched yard became almost unbearable for us to work under the searing sun. Getting under the bulb for grinding it to allow the fin-keel to be fitted in its groove was a strenuous task, so soft is lead to be milled. After four strenuous days I managed fitting permanently the two parts together.

I took the opportunity to install the fin-keel when the crane hoisted VEGA from the trailer to its own cradle and it fitted in the keel trunk like a glove.

Then my mate Oscar and me started to sand the hull to prepare for applying the bottom paint, always working against the watch, since we still had to wait for a while for the paint to set before we put the boat in the water.

I had to install the mast with the boat on the dry, so the shroud lengths could be measured to swage their ends.

Resuming the painting job, we next decided to define a boot-line for the boat. Our first trial was a haphazard interpretation of waves passing through the topsides. Unfortunately our club mates couldn’t understand our artistic vein, so, not to shock anybody, we went back to the conventional, painting a straight horizontal line. To save our face as creative designers we added two small triangles above the boot-line close to the transom, painting them with a different colour.

With the rigging already swaged, we installed the mast permanently. Meanwhile Oscar was finishing small details, fixing deck hardware and taking care of the interior decoration.

And then the “grand finalle”: The 23 of December VEGA was ready to go into the water. Murphy, who had been a gate-crasher in the launching of my Samoa 28 SIRIUS, this time didn’t miss the event too. In the last minute I drilled the holes for installing the heads and galley sea-cocks and the drill landed just on top of the cradle berths. When the crane lifted the boat I had to install the through-hulls in a hurry before the boat was put in the water.

Having my daughter Florence as godmother we broke a champagne bottle on the lead bulb, and Neptune gave free pass to VEGA to find his new element. For a second time in my life I felt an indescribable emotion - launching a sailboat built with my own hands!

The boat floated exactly on its water-line, and inside there was no trace of any leak!... The time has come to let her break loose.

OThe highlight that afternoon was seeing my two ducklings SIRIUS and VEGA together!

After hoisting the borrowed sails, Oscar and I went out to discover how VEGA sailed. Meanwhile my wife Carina and my other eleven guests watched from SIRIUS the evolutions of my new toy, enjoying the comfort and conveniences of my larger boat.

The wind didn’t surpass the eight knots, except in occasional puffs. Even though the borrowed main sail, which required a reef point just to fit in the mast groove, was still somewhat oversized. We pointed effortlessly sailing at six knots, managing to tack in less than 90°. The maneuvers were quick and the boat gained speed rapidly after each tack.

When reaching we could reckon that the boat will fly when using the asymmetrical spinnaker. We managed to sail at five knots with almost no wind.

Eventually we began to shift crews, so others could try the boat too. One of my friends, José Luis, a racer by heart, gave hiss ok to the performance of the Pantanal 25.

You can see in the photo below my good friend Alberto, my companion in many races aboard the Samoa 28, after jumping aboard from SIRIUS.

Back to the club, light hearted and happy with VEGA’s performance, we all went to the bar to toast the great day until late evening. Then my family went to sleep aboard SIRIUS, lashed alongside her new sister.

My wishes are for fair winds to keep blowing in the path of my boats, bringing those unforgettable moments of happiness to our family!!!

Pantanal 25 Enigma II sailing in Brasília

The Pantanal 25 class has already one unit sailing in the Brazilian Central Plateau. This boat is Enigma II, belonging to Ademir Nicaretta, a local sailor who is a keen yacht racer. The boat was built together with two others by Intaschi Nautical Performance, a boat builder from Sao Paulo, Brazil.

No sooner the boat arrived in Brasilia and she was engaged in one of the most important local races, the “Marcílio Dias Regatta”, a traditional event scheduled for the first week of December. This time Enigma II didn't go so well, ending up in a middle position. However the boat showed exciting bursts of speed, giving hope for better performances in the next events, when, for better knowledge of its peculiarities, the boat will be more adequately trimmed.

Enigma II still stationed alongside the club's pier before taking part in her first race.

The Paranoá Lake, where water sports take place in the Brazilian capital, is a dam built during the city's construction with the intention of improving local climate conditions and providing a source of leisure for the future population. Its dimensions are modest, but it is large enough to allow intense sailboat racing the year round. During December winds use to be light and fickle, being winter and spring the best seasons for the sport of sailing.
The prevailing boat types competing in the lake are low freeboard hulls, some of them destitute of interior joinery and lacking the necessary stability to be considered ocean sailboats. Since interior comfort is not an important issue, as the majority of the boats are intended for racing only, they are the most adapted for the local conditions.
Well, that was the kind of competitors awaiting Enigma II first trial. However, according to Ademir, his brand new boat performed above his expectations. He sent to Intaschi Nautical Performance the following e-mail:   

“Dear Jorge Intaschi and other Pantanal 25 supporters,

Even though in this first regatta we had only light winds, we managed to stay ahead of most competitors of all sizes. We tried to sail towards the middle of the lake in the last but one leg and were caught in a lull, having been surpassed by three boats which, up to that point, had been far behind us. We raced under the local rule which penalized our boat heavily, something really weird, since our boat had more freeboard and interior comfort than most others.  
Our Sobstadt sails have a nice shape and good finishing. However the jib seems to be smaller than the sail plan specifies. I'm intending to order a new jib with 30cm more foot length for the 2011 season. The mast rake is perhaps excessive and this for sure will require a fine tuning. What I could notice is that the boat is very technical, demanding constant trimming and weight distribution. Notwithstanding, she responds with alacrity to adjustments, and that, even though tiresome, is very positive for those who really like yacht racing.
We took advantage of being able to operate the drop-keel. The system is working beautifully and made a hell of a difference.

Ademir Nicaretta  

Leaving the pier for the first race in Enigma II career

The Pantanal 25 is a trailerable sailboat intended for camping, and for that matter has an interior comfortable enough to please the heart of the most demanding of  wives. Its drop-keel and its scant 2.44m maximum beam are perfect for taking the boat home and storing it on the garden, bliss in these times of expensive marina fees. On the other hand, in ocean racing, when sailing in light winds with moderate seas, it is enough lifting the keel to decrease the polar moment of inertia and the boat, instead of kowtowing the waves, accelerates like a sports car leaving the fixed keel yachts helplessly behind. (This had been thoroughly demonstrated by Dark Ice, the first Pantanal 25 to sail in Brazil, during the races in which she took part Read the article below: Dark Ice wins for the third time in a row).  However, when sailing in a pond there is no gain in doing that, but the fact that the Pantanal 25 is a narrow boat is a plus when sailing in a breeze, especially when close-hauled.

The winds were fickle along the starting line.
It is noticeable that other boats have much lower freeboards.

The Pantanal 25 is expected to become a one-design class in short time, since there are dozens of boats of the design being built in various countries. Being easily trailerable and being able to be kept at home during the winter months in temperate climate countries, these virtues have attracted sailors from all over the world and its good performance is contributing for that. Being Ademir a well known yachtsman in Brasília, we count on his enthusiasm for the class becoming popular in the Brazilian Central Plateau. There is another unit almost concluded in the neighbor state of Goiás, which most probably will join Enigma II in lake Paranoá.

Enigma II sailing in the shade of much larger boats with considerably taller rigs, even though she is paying to all of them. Something must be wrong with the local rule.

The owner of Intaschi Nautical Performance, Jorge Intaschi, has been a great promoter of the Pantanal 25.  In spite of not being his main business, he decided to invest in a plant to produce the Pantanal 25 industrially, and is investing in state of the art technology to produce composite laminations. With already four boats built, now he has everything ready for series production. For the contentment of seeing one of his boats sailing in the capital of the country, we can reckon that this was camphor shot in the vain to motivate him to produce many other boats.

The boats closer to land were benefited by more constant winds.

A small increase in wind speed allowed Enigma II to gain a few positions.

is being excessively penalized by the local rule.

The great merit of the plans is the fact that the Pantanal 25 is competitive in the racing course, and when there is no race it's just enough to trailer it to other water mirror and live an unforgettable camping adventure, being adequate for two couples to spend a holiday aboard with accommodations to allow pleasurable companionship.

At any rate, being capable of taking part in races and gunk-holing in weekends of beautiful weather in the company of friends is the best of both worlds. Taking the boat home when the fun is over is just another convenience.

Crossing the finish mark. A jib with more sail area will be an improvement for the next season.

Taking Enigma IIback to the club after crossing the finish line.

Soon in 2011 Joaninha, another Pantanal 25 is expected to be launched. This one will stay in Santos, the largest port in Brazil, and will join Dark Ice, the pioneer of the class in that country, the first step towards the establishment of a future fleet. That is what the class needs most, increasing the number of boats in the same place until becoming a one-design category racing for line honors.

Enigna II returns to the club after completing her first race.

But it is not only in Brazil that the Pantanal 25 class begins to show its face. We have hot news from Buenos Aires, Argentina. Daniel D'Angelo, an amateur builder who made the Pantanal 25 Vega all by himself in his home garden, just took his boat to a workshop to be painted. Since the boat is already equipped, it is probable that in a fortnight she will be sailing. As there are various other boats of the class being built in that country, this is an important progress towards the establishment of the one-design class there.

Pantanal 25 Dark Ice wins for the third time in a row

It's becoming each day more evident that the Pantanal 25 is the boat hard to be beaten. For the third year consecutively Dark Ice, a Pantanal 25 built by the Brazilian sailor Jorge Intaschi won the Santos (the largest port in Latin America) ocean race championship in her class, oops, in the class the racing committee decided she should compete, believing she would have slim chances in the class they chose for her in the last event of the championship.

In 2008 and 2009 Dark Ice competed in the first to cross the line category, intended for boats which weren't measured in any handicap rule. Since she obtained line honours in almost every race she took part, sometimes beating boats forty foot long or more, being far and away the fastest boat in the fleet, the other competitors complained that she did not represent the spirit of that category. So the racing committee decided to include her in the RGS Class, a category which measuring rules don't allow boats with large roaches in the mainsail to compete, together with other ridiculous empiric aberrations which heavily penalized the Pantanal 25, a boat designed with the sole intention of providing plenty of fun for its supporters.

So Jorge was obliged to order to a sail-loft an old-fashioned triangular mainsail just to be allowed to take part in the race. What they didn't count with was the fact that in spite of being deprived of her most important weapon, Dark Ice continued being the fastest boat in the scene.

There are Pantanal 25 constructions in the most varied places. This hull is being built by an amateur in Porto Alegre, Brazil.

This last time the boat was crewed by a team of teenagers from a non-profitable organization under the leadership of Captain Douglas, the sailing instructor of the organization.

The first race in the series was quite technical, requiring extreme proficiency from the kids, especially in adjusting the ill-fitted mainsail. Despite a few mistakes, at any rate they were novices in the sport, the boat had an outstanding performance, beating mercilessly the whole fleet, being the first to cross the line, against renowned 32 foot pure racers using Kevlar sails. The heavy penalties imposed to Dark Ice weren't sufficiently heavy to take the first place in corrected time from them. The next races were easier, Dark Ice winning all of them. The boys hardly could believe in their achievement and were anxious to go home to tell their families and friends about their feat. Captain Douglas, who in previous issues of the championship skippered a boat from a different design, admitted to Jorge Intaschi: “whenever I went to the racing course and saw Dark Ice in the starting line, the very fact that your boat was there drove me crazy, and that was the end of the day for me; thank heavens this time the roles were reversed!”   

Dark Ice sailing close-hauled in front of the city of Santos.

Dark Ice victorious racing career helped tremendously in promoting the plans. We intended to give the design inherent speed and plenty of adrenaline. However the astonishing speed of the boat is a by-product of being trailerable. Her narrow, slim hull (2.44m – eight feet - maximum beam) is conceptually fast, and she is practically unbeatable when sailing in light winds. When reaching, thanks to her composite construction lightness, she is able to start surfing quicker than the others, and when starting skimming the waves' crests, by then Dark Ice competitors use to feel helpless. That explains the remarks made above by Captain Douglas.   

Joaninha and another Pantanal 25 in the final stages of construction

Jorge Intaschi already built three other Pantanal 25. One of them, Enigma II, was already delivered to her owner, a sailor from Brazilia, the capital of the country. The owner, as far as we know, is awaiting the visit of the sail maker for the final adjustments in the sails before inaugurating his boat. Another Pantanal 25  built by Jorge, Joaninha, is practically finished and ready to be launched. Jorge acquired a new shed where he intends to build the design in a larger scale from now on. 

Meanwhile the class is spreading quickly in many different countries. The first person who decided to build a Pantanal 25 was Robert Boyd, a yachtsman from Queensland, Australia, who saw in this design the opportunity of having a boat of easy amateur construction that could be taken home in a trailer, avoiding expensive marina fees. By coincidence B & G Yacht Design at that time, 2006, still operated from Rio de Janeiro, Brazil, a few months before changing countries to be established in Perth, Western Australia, where the office is registered presently. It was when we discovered the potential of the class as an escape-valve for those who can not afford buying a boat in a boat show, never mentioning paying expensive monthly fees in marinas. Our move was right on cue, since many other sailors followed Robert Boyd's decision and presently we have builders in dozens of countries. Some of them maintain contact with us, sending us photos of their constructions, or of their boats in the water. The very truth nowadays is that if you want to own a sailboat made in a western country, if you are not filthy rich, you rather make it yourself if you do not want to pay the prohibitive costs of labour that prevail in the western world.       


    Zirrdeli is a Pantanal 25 built in Istambul by her owner, Bahatin Bedir. She is presently   stationed in a marina in the Marmar Sea. There is a second Pantanal 25 being built in Turkey

A good example of this is the case of the Argentinean geologist Daniel D'Angelo. Daniel works in offshore drilling rigs, spending one month embarked and one month off.  In a record breaking short time Daniel managed to build a Pantanal 25 (see in our links page: Pantanal Vega), selecting his home backyard lawn in the great Buenos Aires as his workshop. As winter approached and the finished hull was covered with tarpaulin, he used his barbecue shed to make the superstructure. Since there was barely space enough to build half the deck there, he did not hesitate in building the deck in two pieces, which he joined later with wide fiberglass tapes. It requires a lot of courage and competence for a beginner with little previous experience (he had built before in the same garden Sirius, a Samoa 28 that he uses to race in the weekends and cruise to the neighbouring country Uruguay) to assume a risk like that, but for Daniel this ended up being an easy task, and now hull and superstructure are already assembled, missing very little work for his Pantanal 25 Vega to be launched. Daniel enjoyed so much the boat building activity that he is considering building other boats commercially.

Besides Vega, there are other Pantanal 25 being built in Argentina and there is one in the last stages of construction in Chile.  Our client, Maik Biela, is a German citizen residing in Santiago de Chile.

Maik Biela at the side of his just turned Pantanal 25 hull. Maik is interested in building other boats of the class.

As Germans use to be, he is a perfectionist, and his boat is becoming a work of art. Not being happy enough with the generous radius we provided in the design, he preferred to round still more the cabin edges, making the cabin more efficient concerning aerodynamics, and perhaps more attractive. His skill is arousing interest among Chileans who are asking him quotations for custom constructions.

The outside skin of the deck lamination

A fresh news from the class came from Bahrein. The helicopter pilot Carlos Pinhal recently acquired the plans with the intention of producing a series of Pantanal 25 in that emirate. Having discounts in airfares, he didn't hesitate in flying to Sao Paulo to make a test drive in Dark Ice. He was so enchanted with the model that he decided to acquire the plans and try a local builder for the construction.


Zirrdelli's owner intended to keep his boat in the water and for that matter opted for fixing her keel, what brought an unsuspected appearance of amplitude to the interior.

And just to finish our story, in another coincidence, the latest client to order the Pantanal 25 plans came exactly from the country where came our first order, to be more precise, from Perth, Western Australia, where the office is established now. Small world!!!

Pantanal 25 - Close to becoming an international class

Favourable winds are blowing in the direction of the Pantanal 25 class. Intaschi Nautical Perfrmance, together with Coopermarine, two companies from the state of São Paulo, Brazil, associated in the production and sales of this boat, just accomplished the third sale of a Pantanal 25, which will be produced using the moulds Jorge Intaschi, the chairman of Intaschi Nautical Performance, produced when constructing Dark Ice, the Pantanal 25 he built for his own use.

These moulds, sent to Coopermarine, a boatbuilding factory that woks as a cooperative, already produced two hulls of the class, which soon will be sailing. With the new sale already confirmed, it is missing one unit more to be possible to establish the Pantanal 25 as an official Brazilian class, not mentioning the addition of dozens of amateur builders who are in various phases of construction in different parts of this country.

Ronaldo Agondi, the Coopermarine director, took the chance of having these orders to complete the set of moulds of the interior arrangement, which were still lacking. These moulds are in their final stage of completion and are becoming very attractive, showing excellent level of craftsmanship and good design, with rounded walls and studied ergonomics.

With such nice work being obtained, the Pantanal 25 produced by Coopermarine has, for sure, a winning commercial career, either in the local market, or internationally. Since the class is spreading its number of builders in the most varied countries, we are confident that any factory with a line of production of the boat will have a good chance of success in obtaining local and overseas clients.    

The vanity basin counter wall built by Coopermarine has curved lines to enhance standing headroom area inside the heads.

We have been regularly reporting about the racing career of the Pantanal 25 Dark Ice.

This boat won most races she competed in her 2008/2009 debut in the Brazilian offshore racing scene. This July she was carefully prepared for the most important event in the South American racing calendar, the Ilha Bela International Sailing Week.

Demonstrating an awesome speed potential, Dark Ice reached the windward mark in the long distance race together with the ‘big wigs' of the competition, and despite having the preference, had its bowsprit hit by a fifty-seven, U$2,800,000.00 brand new racing machine, and for everyone's amazement, had no hull damage, except for a bent bowsprit.

The accident ruined the series for Dark Ice, but who cares after this surprising demonstration of structural integrity? We reckon that what saved the Pantanal 25 was its light displacement, and like a ping-pong ball when hit by a racket, it simply slipped sideways, causing no damage to the boat. This is undoubtedly the great advantage of sandwich composite construction.

The bowsprit bent with the impact of the collision without causing any harm to the topside

However what brought the Pantanal 25 back to the headlines was the article published by Revista Náutica, a local yachting magazine, in its September issue, comparing this design with another twenty-five foot cruiser-racer, also with a drop-keel system installed.

The comparison was somewhat inappropriate, since the Pantanal 25 is intended to be a camping boat, with emphasis in maximum trailerability, with its scant 2.44m (eight feet) beam, a strategic measurement in the United States and Canada, where this beam does not require special license to be trailed, as compared to the 20% larger beam of the other boat. Notwithstanding, in spite of the smaller beam, the Pantanal 25 visibly outstands the other boat in interior layout comfort, taking into account that it has two double berths, secluded heads with door and room for six persons to sleep when cruising. But the important remark is what the journalist reported in his text: “…But she is also a good performer in the racing course, thanks to her generous sail area and her light displacement, especially when sailing close-hauled or in any point of trim when the wind is light...

Zirrdeli, the first Pantanal 25 to be launched, is stationed in the Marmara Sea. 

We still worked in Rio de Janeiro when we completed the Pantanal 25 design. By chance, however, the first to acquire the plans was Robert Boyd, from New South Wales, Australia. Being our first client for this specific design, in a gesture of gratefulness, we presented him with a touristic book about the Pantanal echo-system, one of the most beautiful regions in the world, for the landscape of its swamps and its diversity of wild-life. Even though he is very enthusiastic about the plans, Robert had to postpone the beginning of his construction for personal reasons. On the other hand, the second ones to acquire the plans, the Turkish friends Orhan Sati & Bahatin Bedir, from Istanbul, to our surprise, less than one year later, sent us very nice photos of Zirrdeli, the Pantanal 25 they built together, stationed in a marina in the Marmara Sea. Their boat, as far as we know, is the first of the class to sail.

However this was just the beginning. Presently we have builders in different stages of construction in various countries in four continents, some of them having informed us about their intention to produce the model commercially. So we are quite confident that soon the Pantanal 25 will be recognized as an international class

Dark Ice, the first Pantanal 25 to sail in Brazil

The third Intaschi Nautical Performance/Coopermarine  sale, together with Dark  Ice, and the other boats under construction in Brazil, will allow the homologation as a one-design class. The same applies to other countries where three or more boats are being built. Those who have their constructions under way, wanting to send us good photos of their boats, we are interested in reporting about their progress in our news.

The Pantanal 25 above, Rotfarth,  together with Enigma II, both built by Coopermarine, soon will be sailing in different nautical centres, one in the Santos region, and the other in Brasilia, the country's capital.

Pantanal 25 Being Built in Chile - Maik Biela

My name is Maik Biela. I'm 37 years old, German, and presently live in Santiago de Chile.

I studied professional craftsmanship in carpentry some twenty years ago in my country, Germany. I left Germany almost ten years ago to search something new, and lived several years in the USA, where I also worked in my profession, as a contractor in the construction business.

During this time I started visiting Chile, and was thinking why not to go there and start something new, as I'm always looking and searching for, something really new, and here I am, also working as a contractor in construction with my professional skills and craftsmanship.

Like always, I was interested in boats, but this hobby is not really affordable in Germany, so I was searching for possibilities to start doing something in Chile, since there is a lot of ocean around this country, and this gives you a lot of options.

So I obtained my captain licence to start sailing in a small Boat-Club called Quintero.
I was lucky because just after I received my licence I had right away the possibility to sail in races sponsored by this same club, and we did very well, won a lot of races and this was when I wanted to have my own sailboat, to go around, and enjoy water and nature on my own.

So I started searching how I could get a good sailboat for a good budget, but buying new from the factory was not an option for me, so I was thinking why not building one??!!

After searching and searching, I finally found Roberto Barros Yacht Design, and I was much exited with the design of their boats. I ordered study plans from various providers of plans for amateur boat building, but finally chose a design from Roberto Barros Yacht Design, this because it was a modern design, and I wanted to start with a boat where I have space, neither too big, nor too small, and also for a reasonable budget.

I chose the Pantanal 25 and finally ordered its whole set of plans. Then I began studying the plans with mixed feelings, sometimes I was questioning my skills to build a boat like this, but started building anyway and thinking: this has to work out, whatever effort it costs because I want a sailboat!!!

I contacted Roberto Barros's naval architect Luis Gouveia and tried to clear a few questions about the construction and that worked perfectly, getting quick responses to my questions, so I was looking forward to receive the plans and get started as soon as possible.

I started in March 2009 to search wood for the hull construction, and started building that same March. This was so quick, I couldn't believe it. I was fascinated how everything worked out with plans and the building process and my skills are more than enough to go further building in my spare time, and now it's difficult to separate me from the process after long hours of building, it is fascinating!!!

I finished the hull in 4 months (only in my spare time). Then I called a couple of friends to help me out to turn the hull, and now I can get started to finish the interior...The hull turnover was very exiting for me, because I really did not know how it was going to work out, but the answer is in the pictures, everything worked great!!! I also have to say: I'm looking in my general work many of the details, almost ridiculous, and perhaps this is also the answer, that everything worked out till now.

My experience to build a boat in Chile is mixed, I'm sorry to say, but I must admit, it's not a builder's paradise, because it's very complicate to find specific materials for this work, and a lot of companies here are only interested in selling products in large quantities, what make things more difficult, so I searched the internet, often for hours on end, called thousands of people until I had a solution for the materials I needed, and also contacted Luis Gouveia from Yacht Design very often to find solutions for materials.

Finally I got what I searched. I was a bit tired but satisfied, and could go further with the building.
A lot of people are paying attention if they realize that somebody builds a boat, and I had various talks about this. This is also a very interesting part of building your own boat. Till now I built my boat alone, since I want to enjoy everything during the building process all by myself. As I said, I'm much focused on details, and because of this I prefer to finish the boat alone, except the hull turnover and heavy moving, whatever is impossible to do alone.

I'm exited to go further with the whole building, and can't wait to start sailing with the Pantanal.
I'm that bit crazy, I'm already thinking to build another boat from Roberto Barros Yacht Design, but I have to finish first the Pantanal, and then I'll see which boat I will do next.

I will thank Roberto Barros Yacht Design, that they made it possible with their designs to build a perfect and modern boat for an affordable budget, and also to have fun in the building process. I also want to mention that they provide an incredible customer service, being interested in their builders!!!!

It's fantastic to buy a brand new boat from the factory, but the experience that I get from building my own boat is indescribable!!!

Thank's very much to all, and Roberto Barros Yacht Design for publishing my pictures and publishing my experience. Thanks also to my friends who helped me out in the hull turnover!!!!!

Will keep you updated,

Best regards

Pantanal 25 being built in Argentina - Daniel D'Angelo

After concluding the construction of the Samoa 28 Sirius, which I built in my home garden, I started using it intensively since its launching day. Not so long after, however, still remembering how pleasurable its construction had been, and how rewarding was sailing on her afterwards, I decided to build another boat from a different design, this time a Pantanal 25.

This design interested me for various reasons, being its capacity of draught control, low displacement and fast building technique the most important points in my decision. Since the building method did not differ significantly from the one adopted for the Sirius (foam sandwich for the Pantanal 25, against wooden strip-planking sandwich for the Sirius), I reckoned that the work would be considerably lesser than it took to build the former one (two years, eleven months)…and so far I didn't find reasons to doubt about my prediction. The foam is extremely easy to be handled and sanding is a task for children! So, in April, 2009, I started the construction of “Vega”.

With my previous experience and the confidence of being able to construct a good boat, the work is progressing with celerity in spite of the chilly weather in Buenos Aires this time of the year.

Taking advantage of what was left from autumn; I managed to conclude the outside lamination of the hull in two weeks. (The same job when building Sirius took two months to be accomplished!) Coping simultaneously with different working fronts, I started to build the drop-keel trunk, rudder and fin-keel hydrofoil framing.

When I resumed the work in late July, the cold weather prevented me to deal with anything that required epoxy usage while working in the open where the hull was being assembled. So I took a radical decision: I would build the superstructure inside the barbecue shed in my garden, making it in two halves to be joined later. This way in two weeks I had the fore half concluded, which I brought to the outside, leaving it on the mown, while I opened room to build the other half.

This part was a bit more troublesome to build, since its moulds were more complex and the tightness of the room available made it difficult for me to move around the working area. Before having to interrupt the construction, since the time off from my job was finishing, I managed to apply the foam sandwich along the whole aft part of the superstructure and started sheathing it with fibreglass, the remaining left undone representing one more day of work at most!

Meanwhile I ordered the mast and boom from a renowned local spar maker as well as the special fittings from a specialized hardware workshop, while with another Argentinean builder of Pantanal 25, Tomas Orcoyen, we ordered together to a foundry the drop-keel bulb.

On my next time off, in September, I'll start the installation of the structural bulkheads, partitions and furniture, a task that I reckon will take a fortnight to be accomplished. The sail inventory, at least to start with, I intend to use the ones from my bigger yacht, which surprisingly approximately fits in the smaller boat!

It is bliss to work with foam sandwich/epoxy. All going well, and Mother Nature giving me a hand, it is possible that I manage to finish the boat before scheduled, December 2009…an absolute record for me!!!

I am quite anxious to try her and be able to enjoy her huge cockpit already assembled at the aft half of the superstructure, a reason for compliments from our visitors! It will be quite rewarding to see how she performs in the tricky waters of River Plate. The expectation is that she will be a fast boat

The Argentinean geologist Daniel D'Angelo was the first person to complete the construction of a Samoa 28 (see his site: and having enjoyed the hobby of boatbuilding, he is in the way of a second challenge, now the Pantanal 25 Vega.

Pantanal 25 is hard to be beaten in light wind conditions.

Jorge Instaschi,, the Pantanal 25 class coordinator in Brazil, sent us the following e-mail reporting the class latest news:

“We have another Pantanal 25 hull already constructed. The latest one is Rotfahrt. She was extracted from the mould this week, and her superstructure is already laminated.
What a gloss!!!. This second unit from the same mould is going to incorporate all the improvements (sails, keel, deck layout, etc) we developed in these last seven months of racing with Dark Ice, our first Pantanal 25 to take part in the racing course.

The new boat is basically intended to participate in the same events as Dark Ice, the 2009 Santos Offshore Racing Championship. Dark Ice, however has a more ambitious plans fot this year and we have a schedule to send her to other important events in the Brazilian racing agenda.

For bad luck, (or would it be good luck?), the new boat most probably will over-sail our dear Dark Ice, since she will be lighter, thanks to a more accurate vacuum bagging technique applied in the second boat lamination. We are counting on hard times for Dark Ice from now on.

The lamination of Enigma II, the third Pantanal 25 to be built from the same mould already started, and she will also be completed straightaway. This new boat is being prepared to race under the “Brasilia Rule”, a measuring formula adopted by the capital of the country's sailing fleet, in Paranoá Lake, the important water mirror in Brazil's capital. Taking into account Mr Ademir Micareta's, Enigma II's owner, renowned sailing skills, this Pantanal 25 will most probably steal the show in the 2009/2010 racing seasons at Lake Paranoá.

It is exciting coming to learn how the Pantanal Class will spread to other sailing centres. We at Performance Pantanal 25 consider each new hull of the class as if it was a son. We are glad to follow the construction of each of them, doing our best towards producing a better boat at each lamination, and we are prepared to give all the necessary support to the new owners after launching, explaining to them all the tricks Dark Ice already taught us during these seven months of intensive sailing”.

Meanwhile the Pantanal 25 Dark Ice has been involved with the season's first regattas at the Santos Racing Fleet. She took part in three races in a roll, all of them in light winds, the conditions when the Pantanal 25 had already shown that she is the boat to be beaten.
Jorge Intaschi repports:

“This year we are trying new adjustments for Dark Ice sailing trim which seem to be working beautifully. At the first regatta of the new season, even though with a renovated crew, we won the race. Jones, the helmsman making his debut at this function, was really impressed with the quick acceleration of the boat at the least breadth of wind, keeping its speed in almost no wind. Newton, another crew who came to give us a hand, was absolutely infatuated with the boat's performance.

The second race we had Dimas, our last season's helmsman, when we were the Santos Offshore Racing Championship winners, back to the tiller, conducting Dark Ice with great skill one more time, and he did not disappoint us. We opened an even more impressive leadership over the other competitors, as if our boat was employing another sort of propulsion.

Leonardo, one of our competitors, from the Ranger 26 “Rainha”, later sent an e-mail to the Santos Offshore Racing Association forum, telling his impressions about the races during this weekend:   
To my surprise the races during this weekend turned up to be very pleasant. Saturday we had to round Pascoal Mountain Island in a course where in the past  I seldom saw any puff of wind. This time, however, the wind was quite constant. Straight from the start, Dark Ice jumped ahead with such an astonishing speed that it looked like they were sailing with a private wind, such was the difference between them and the other boats. Notwithstanding, let's face it, they were sailing much faster then us all. They rounded the island far ahead the second boat, and they only had to administrate the huge advantage from then on.

Sunday the wind was more typical of that area, just a lick of it! Again Dark Ice seemed to be the only boat capable of sailing in those conditions, and once more she jumped ahead of all other competitors. The race ended up being cancelled, but once again Dark Ice was far ahead of any boat…

Pantanal 25 Dark Ice wins her first championship

Good news from the Pantanal 25 class arrived this week.
On the February, 7th was scheduled the prize award party for the 2008 Santos (the most important Brazilian port) Ocean Racing Championship. Guess which boat was the most awarded that night?

If you bet it was the Pantanal 25 Dark Ice, the first boat of this promising class to be launched in Brazil, you hit the nail on the head.
Yes, it was exactly Dark Ice, that very boat making her debut in the racing scene and which performance was still to be seen, crewed by a team of novices who had yet to discover how this new design behaved, learning about her abilities along the racing course.

And it wasn't little what was learned! They discovered that her speed was simply fantastic in light winds, capable of overtaking the whole local fleet, regardless of the size of the competitors.

When sailing in fresher winds, she still sailed fast, but in those conditions water line length prevailed and Dark Ice didn't manage to beat the larger boats.

In short: even though she only began to participate in the series already in its fourth race, she managed to win the championship one race before the last one.

The 7th of February was a busy day for the owner and builder of Dark Ice, Jorge Intaschi. Early in the morning he had an appointment with a racing sailor from Brasilia who had come to Santos just to get to know the Pantanal 25.

Before taking his guest out to sail, Jorge went with him to Coopermarine, the manufacturing co-operative engaged in series producing the Pantanal 25. By sheer luck the factory was giving the finishing touches to a motor yacht which would be delivered to Brasilia, the visitor's town, in the next few days, demonstrating to the potential client the high standard of the factory workmanship.
In another coincidence, the first Coopermarine client for a Pantanal 25, the yachtsman from Sao Paulo Marcelino Magalhães was also visiting the factory, bringing with him a very special red gel-coat he had chosen to apply on his hull. All that fuss around the co-operative's new venture deeply impressed the Brasilia's citizen, and he was counting the minutes to go to the marina and finally getting to know the boat he was so anxious to try.

A few days earlier the locally prestigious Brazilian magazine Revista Náutica had tested Dark Ice for one of its regular evaluation reports. That day the reporters suggested changing the appointment for another occasion, with a more reliable wind, believing that with the ghostly wind of the day the boat wouldn't move. To their surprise, however, they discovered that Dark Ice jumped ahead with incredible acceleration at the lightest puff of wind, showing them that they needn't be worried about accomplishing the test.
This Saturday the wind conditions were no different: light puffy winds from various directions.. Jorge Intaschi's guest took the tiller and stayed there for the next six hours, marveled with the speed of the boat and her easiness to be controlled. It wasn't surprising that he confirmed the order for a Pantanal 25 to race in Paranoá Lake, the sailing ground of the country's capital.

When the test-drive finally satisfied Jorge's guest, our host invited him to participate in the prize awarding party for the 2008 Santos Ocean Racing Championship. This was the high-light of the Pantanal 25 class prestige that day. That almost unknown model stole the show, and that evening she was the boat which won more prizes, stirring the most varied gossips about her performance among the participants in the event..

No wonder Jorge and his crew were very happy and the visitor deeply impressed with such interest in the new design. To crown it all a yachtsman from Niteroi, the Rio de Janeiro's neighbour city, confirmed his order for another Pantanal 25 to be built by Coopermarine. Jorge, perhaps because of high adrenaline triggered by such sudden success, also announced his intention in building Wave Runner, his next Pantanal 25.

This was the hot news direct from Sao Paulo, the most important Brazilian state and nautical centre.
Meanwhile, our client Danial D'Angelo, from Buenos Aires, Argentina, is begining the construction of a Pantanal 25, which should be ready in six months time. As he is an experienced amateur boat builder, for he was the first to finish the construction of a Samoa 28, of which there are dozens in construction in various countries, there is little doubt he will succeed in keeping his time-table. While all the others are still building their Samoas 28, Daniel is enjoying his lovely Sirius, cruising with his family around the River Plate, between Argentina and Uruguay.

With boats being built in a dozen different countries, from Sweden to Australia, and with the first ones already sailing, after Dark Ice's demonstration of competence in the racing field, we have all reasons to believe that very soon the Pantanal 25 will become a popular international class.

Pantanal 25 Dark Ice wins her first races

The Pantanal 25 design was developed to be a trailerable cruiser/racer with a good a speed potential. When Dark Ice, the first Pantanal 25 to be launched, began to participate on the 2008 Santos, (the largest Brazilian port and the most important yachting centre in the whole country), racing season, we knew the moment of truth had arrived.

After six months of hard work trying to produce a design that would please people of both sexes from the most different places, and knowing that we could not disappoint them with just an indifferent performance in the racing course, imagine how anxious we were trying to guess how fast the boat would go after the starting gun had fired.

We should have been more relaxed, however. Soon we were to receive the first news confirming that the boat was up to our expectations.
The Pantanal 25 design had already caused bursts of enthusiasm among many competition minded sailors. On the other hand, nobody wanted to bet in the speed potential of a twenty-five footer provided with galley, enclosed heads, two comfortable double berths and a nice dinette with place for six persons to sit around a comfortable drop leaf table, before a conclusive test on the racing course had been accomplished.

Jorge Intaschi, the builder of Dark Ice, has done a first class job when constructing the boat. He followed faithfully the project specifications, building the boat in foam sandwich, exactly as recommended in the design's scantlings. This was of utmost importance, since the true potential of the boat would be jeopardized if its weight surpassed the theoretical displacement.

Dark Ice, in spite of being hardly sailed yet and having to compete for line honours, since she didn't measure in any existing local rule, was thrown into the arena with the difficult mission of proving her merits against boats much larger than she is.

The first race was epic. Dark Ice crossed the starting line behind the whole fleet. The wind was very light and she drifted among the other yachts with the elegance of a dolphin. The course was windward-leeward, and when beating to the windward mark, she passed all boats except a thirty-four foot racing machine, crossing the line in second place overall.

The second race Dark Ice participated was more exhilarating still. As it already happened before, the crew still was adjusting the sail trim when they heard the starting gun. The wind was light, so the loss for a bad start was immaterial. Pointing harder and sailing faster than any other boat in the race, they lead the race at the windward mark and from there on never lost their leadership, arriving half a leg before the second boat, a thirty-four footer. When overtaking the other boats,  Jorge threw them ice-cold water bottles, just as a friendly, or was it a teasing, gesture.

When the race was over the other crews admitted that in light winds Dark Ice was “the boat”, sailing faster and pointing harder than anyone else.
The third and fourth races, one week after, the wind was stronger then, and at that time, in spite of sailing very well and still pointing harder than other yachts, water line length prevailed and the best Black Ice managed to do was a second to arrive position. In short, Jorge Intaschi is absolutely pleased with the performance of his boat and we thank him for showing us that he made a good job as an amateur builder, as well as an ocean racing skipper.

The Pantanal 25 class is already spread. The first to get into the club was a client from New South Whales. Then came new builders from the U.S., Switzerland, Italy, Sweden, Brazil, Canada, Turkey, Chile, Spain, Greece and other countries. Now that there are some of them already sailing, and as the Pantanal 25s is continually expanding in numbers, we hope soon it becomes an international one design class. If you are building a Pantanal 25, or finished the construction of one of them, wanting to inform us about your experience, we are willing to transmit to other members of the group.

Pantanal 25 made in Turkey

Last June, 4, 2008 we received this laconic e-mail with three excellent pictures of the first Pantanal 25 made in Turkey:

Dear Roberto
We think this is the first one.
Thank you very much for your very nice plans. (Pantanal 25)
We built together. Please see her in the water.

Observing Zirrdeli’s photos was a very nice surprise for us. At first place because the boat is superbly well built, with a degree of sophistication, like for instance, teak covered cockpit seats, seldom found in boats of amateur construction. It also impressed us the fact that the two friends surpassed all obstacles totally unassisted by us, since they did not require any further information besides the ones provided with the plans. So our surprise came in a double dose, and receiving these photos gave us an incommensurable satisfaction.
However, another surprise was expecting us; a client of ours, Birol Ozer, who acquired the plans far later, probably influenced by Zirrdeli’s superb finishing details, sent us an e-mail informing that he also had completed the construction of his Pantanal 25 hull.
He wrote:

Hi Luis,
I hope you and your family are fine.
I am sending you a photo of my Pantanal 25
This weekend I’m intending to turn her upside.
I’m afraid of this action.
Kind regards.
Birol Ozer

The Pantanal 25 class is just getting outside its egg-shell. When we decided to design a trailerable cruising sail boat with more creature comforts than most other similar boats, we couldn’t dream with the immediate approval of our ideas by so many sailors in the most varied places. Since its introduction, the class never stopped increasing in aficionados and there are dozens of builders in various countries working hard to complete their boats.

The first chance we had to watch a video of a Pantanal 25 sailing took place last April when Dark Ice, the boat built in Campinas, Brazil, by Jorge Intaschi went for her first sea trial. This video is becoming very popular, with more than 3.000 visits in two months. Soon Jorge intends to produce a second one, when he will try a larger asymmetric spinnaker on his boat.

We are praying for Aeolus to present him with a nice and fresh breeze for us to appreciate Dark Ice’s wake.
Jorge Intaschi is installing a plant to produce the Pantanal 25 commercially and we hope soon he will be starting his line of production.

Record crop of boats from our designs getting ready to be launched

This season we have good reasons to commemorate. To toast our first anniversary of operation in Perth, Western Australia, it seems that our builders wanted to reward us with a record number of boats from our designs being finished practically at the same time.
One of them, Dark Ice, the first Pantanal 25 to go to the water, was the premature baby of this list. Last month she went sailing and this June she will be competing in the most important event of the Brazilian racing calendar, the Ilha Bela Sailing Week.
Jorge Intaschi, her builder, obtained a sponsorship to finance the expenses to participate in this series, and at the moment is training a qualified crew, doing his best to show the boat's potential. Dark Ice had already been tested, when she demonstrated being capable of impressive bursts of speed, even when sailing in light air. (See our report - Pantanal 25 Dark Ice first trial. The You Tube video shown in this article, reached 2,890 views in May, 24.).

The other boat just launched, still needing to be rigged, is also the first of her design to go to the water. She is the Green Flash ORC33 Class prototype built in Joinville, State of Santa Catarina, Southern Brazil, by João de Deus Assis. This boat is one of the firsts of this class to be concluded world wide. In Brazil she probably will compete in the ORC Internationa class, once there are no other sister-ships to race for line honours.

The other boat that is with her stem very close to the water is also the first of her class to be finished. We are referring to Sirius, the pioneer of the Samoa 28 Class.
The Argentinean geologist Daniel D'Angelo, built her in Buenos Aires, almost unassisted during his days off the South Atlantic continental shelf oil rig where he works. (His site is: )

Pantanal 25 Dark Ice first trial.
This article is simultaneously published in and in

See Dark Ice first sail film. The wind speed is approximatelly five knots.

Last Easter Friday was a happy day for the Pantanal 25 class. Dark Ice, the Pantanal 25 we showed pictures of her being transported by trailer in an earlier report, went for her first trial last Easter in Santos, the important Brazilian port and the most developed nautical centre in this country.

There are many boats of this class under construction in a dozen different countries, and at least another one is already sailing. However it was Dark Ice the first one to send us a thorough report and a complete set of photos of her first tacks on the water. We received by e-mail a beautiful photo of another Pantanal 25 built in Turkey by an amateur, and many others are not far from completion, but this was the first actual chance to know how does the Pantanal 25 behave.

Dark Ice was built in Campinas, a city two hundred km away from the sea, by Jorge Intaschi, an amateur who saw in the Pantanal 25 design the perfect boat for his requirements. Jorge, a computer analyst, is a dealer in the car sales business. As it is so often the case nowadays, he has a very limited spare time for his preferred hobby, the sport of competitive sailing. Living so far from the sea and with such a demanding business, he needed a boat that could be stored at his home garage during the long stretches when he couldn't afford having a holyday, and, on the other hand, when going to the sea, he wished a boat comfortable enough for his family to spend the weekend aboard, preferably with the amenities required for a pleasant stay, like enclosed heads, private cabin and a handy galley. When he discovered the Pantanal 25, he knew straightaway that this was exactly the boat for him.

He was one of the firsts to acquire the plans, which had been published just a few weeks before. He was so enthusiastic about the Pantanal 25 potential that he decided to begin a boat-building business to produce this model in series. He opened a company in partnership with his brother Wagner, and a few weeks later he was already starting the construction of the plugs required for the fabrication of the production moulds.

Even though the two brothers were experienced entrepreneurs, this field of activity was a total novelty for them. Despite their lack of technical knowledge, they decided to produce first class tooling and top quality infusion lamination. In January 2007, they installed their workshop, and the first decision they made was to acquire a boot at the Sao Paulo Boat Show, scheduled for October 2007.

You can imagine they had to work like bats out of hell not to loose the show, and for very bad luck, or perhaps because of the hurry, Jorge fell from the plug's deck, rupturing all ligaments of one of his knees. He went to the boat show in a wheel-chair since he didn't accept to be operated on before the event was finished. He had no reasons to blame that detached decision, since his boat was one of stars of the event and he managed to accomplish fifteen firm orders along the duration of the show, with a permanent queue of hundreds of persons waiting to climb aboard. Now he is recovering from the surgery, and the great day has come for the sea trials of Dark Ice, the very boat produced for the boat show.

Assuming they hadn't enough experience to run the whole enterprise without a skilled assistance, they hired Eduardo Arena, a highly prized technician in the yacht building industry and a renowned model stylist in the confection of plugs. His participation was a real blessing, since he is also a keen racing sailor, and above all, he is a great supporter of the model.

That Friday wasn't very inviting. The sky was cast with heavy clouds and the wind was light and variable. A cold front was expected the next day, so an improvement in the weather pattern was out of the question.

With his knee still requiring attention, Jorge Intaschi decided to watch and take the first pictures of his new toy crossing her first waves from the comfort of a speed boat's fly-bridge. Eduardo Arena was going to be the test driver, assisted by a rigger and a professional sailor.

The crew couldn't be more qualified for the occasion, and undoubtedly all those involved with the enterprise were visibly excited with what was going to happen in the next few hours. In the rush of preparation all halyard and sheet tails were yet to be trimmed to their proper lengths, while the brand new sails were for the first time out of their bags.

The launching down the slipway was uneventful, and in an instant Dark Ice was under tow. At that moment many of the myriad of doubts that populate the hearts of all boat builders were dissipated. The boat floated correctly on her waterline with a perfect trim, in spite of the three stocky crewmembers staying on the cockpit.

When the motor yacht surpassed Dark Ice's hull speed, Eduardo felt the rudder too heavy to steer, giving him the impression that it required balancing. This, as soon as the boat started to sail, was proved to be unnecessary, and in the circumstances of being under tow, all that would be required was to lift the blade a bit, which in the case of the Pantanal 25, has infinite adjustment.

Jorge, despite a slight increase in heartbeats, was seeing for the first time his creation sailing close-hauled. And how nicely she performed; in five knots of wind the boat was sailing at practically the same speed. The initial stability was excellent and the boat seemed to be crossing the small seas effortlessly, leaving behind a very clean wake.

Demonstrating very good pointing ability, the boat came about showing impressive acceleration in the new tack. Jorge exulted from the fly-bridge, blaming his damned knee for not being able to be at the tiller at that moment.

The wind increased in strength to about twelve knots, and then the boat, which up to then was quite stiff, quickly lost some stability, heeling to a bit more than 15°. Being a narrow boat with her beam on the water line almost the same as her maximum beam, this was foreknowable, but the good news was that she was perfectly balanced, accelerating without the rudder loosing its grip.

The return trip was useful in testing the boat in a broad reach. The wind was light and the asymmetrical spinnaker wasn't capable of showing all its potential, but that was just the first trial, and many others will follow soon. The photos Jorge took from the motor boat are not spectacular, since the sky was overcast and the atmosphere misty. But that was only Dark Ice baptisms and we still are expecting a lot of good news about this design.

How does the Pantanal 25 look like?

The Pantanal 25 is one of the most comfortable trailerable sail boats for camping purposes available as stock plan for amateur or professional construction. With two cabins, enclosed heads, a handy galley and a spacious dinette, she is a fast boat with creature comforts seldom found in a boat of her size. Perhaps for these reasons the Pantanal 25 attracted the interest of so many potential builders. Just a few months after the introduction of the plans we received orders from boaters from many different countries in four continents.

Now the first Pantanal 25 units are being concluded and in the next couple of months some of them will be sailing. This is very exciting and we intend to inform you, who visit our home page regularly, about the latest news of the class.

The hottest news at the moment is the Pantanal 25 produced by Intaschi Nautical Performance.

The two brothers, Jorge and Wagner Intaschi, from Sumaré, State of Sao Paulo, Brazil, decided to build industrially the Pantanal 25 under the trade mark Performance 25. (See their site:

They only began to build the plug to make the necessary moulds for series production in the beginning of 2007, and now, less than one year from the day they started to work; they already have their first unit ready for sea trials

The Intaschi brothers are new at the trade; however they are experienced entrepreneurs, running three other companies which allowed them to finance establishing this new plant, producing first class tooling and top quality infusion lamination. In March 2007, when the construction of the plug achieved a stage of near completion, they acquired a boot at the Sao Paulo Boat Show, which was scheduled for October 2007, to expose their future model.

You can imagine they had to run not to loose the show and for shear bad luck, Jorge fell from the plug's deck, rupturing all ligaments of one of his knees. He went to the boat show in a wheel-chair because he didn't accept to be operated on before the event was finished. Now he is recovering from the surgery and we hope soon he will be testing the first Pantanal 25 to sail, which he had to delay for a while due to his injured knee.

This January our partner Luis Gouveia, who is presently running RBYD office from Perth, Western Australia, came to Brazil on a business trip and took the opportunity to pay a visit to their plant, and could witness personally the high standard of their work. It wasn’t for luck that the Pantanal 25 had been one of the stars of the boat show, with a permanent queue of hundreds of persons waiting to climb aboard. At the end of the event they had 15 firm orders and also managed to have a report published by one of the Brazilian most prestigious yachting magazines.

Luis talked to Jorge about the possibility of offering their boat as a kit for further completion by the purchaser and he showed great interest in doing it. At the moment Jorge is intending to sell the boat ready to sail in a version he will call Performance 25, and the kit as an unfinished boat in four stages of completion. Since the plans are intended for amateur construction, as well as professional, with a building manual explaining step by step how to construct and assemble the whole boat, we believe there is no obstacle for the amateur to complete the job, in whatever stage of construction he chooses to acquire the boat.

Jorge sent us first hand photos of the Pantanal 25 n° 1, which we are proud to publish in this report, and next, as soon as we have the photos we are so anxious to receive, we will show the first tacks of this new design sailing full canvassed in the South Atlantic.

Pantanal 25. Our pretty baby is essaying her first steps.

The Pantanal 25 is surprising us since its introduction in 2006 as a stock plan for amateur and professional construction. We never dreamed with such a quick acceptance by the general public of our 25 foot trailerable sail boat. We don’t know if it was because she could be stored in the home garden, this way saving expensive marina fees, or if the reason for such a good start was the fact that she possesses unrivalled accommodations for up to six persons and an adequate headroom for her size, about one foot above the average of similar designs available in the market.

In less than one year we had already dozens of these boats being built, by amateurs and professionals alike in five different countries up to now. By sheer coincidence the first plan we sold was to Australia, the country to which our office was going to move a few months after.

The first hulls didn’t take long to be completed and then Intaschi Nautical Performance, a company from the state of Sao Paulo, Brazil,, decided to build this design commercially, and next October will be exposing their first unit at the Sao Paulo Boat Show, under the trade mark Pantanal/Performance25. (We are illustrating this article with some photos of their tooling)
Meanwhile the first Pantanal 25 to be completed was launched in Turkey, and a new boat builder will start producing the model in Santiago, Chile.

Together with the various amateur constructed units close to being launched, soon we will have sufficient number of boats in the water to establish a new class and we hope, with the contribution of the professional builders, that very soon the class will be well established in many sailing centres.

Pantanal 25 will be produced in series.

Barracuda Náutica, from São Paulo, Brazil, is starting a commercial production of the Pantanal 25. The factory intends to build these boats in sandwich, exactly as specified in the plans, employing the infusion system of lamination. Their intention is to produce a light boat with uniformity of weight and structural integrity, which is an important factor for the class.
The Pantanal 25 is quickly becoming a recognized success, with boats being built in various countries. It seems that a trailerable cruiser-racer with its characteristic was really missing in the nautical market, therefore the great enthusiasm for the design. We have already Pantanal 25 builders starting the construction in various parts of Brazil, in Australia and in Europe. We soon hope to establish the Pantanal 25 International Class, and considering that in less than six months the first boats are expected to be launched, this achievement will probably happen in 2007.

Pantanal 25 class News

Different builders, amateurs and professionals, are finding out that constructing a Pantanal 25 is a simple task to be accomplished.
This new design is beginning to be constructed in various places and the first results are very promising. Our pioneering builders are sending us the photos of their work and looking at the pictures we received; we can assume they are managing to achieve excellent results.

The race for the first Pantanal 25 to be launched started in Porto Alegre, Southern Brazil. Our client, Carlos Zanella Sitchner, a civil architect, was the first builder to complete a hull of the class. He used wooden strips as core material, and in spite of never having built a boat before, made an excellent job, and presently is constructing the interior and superstructure.

Meanwhile in São Paulo, the largest Brazilian city, Barracuda Nautica, a commercial boat factory, decided to produce the Pantanal 25 industrially. They produced the tooling of hull, deck and furniture and soon will be introducing their product in the market. The plugs they made were intended to become a boat and were built strictly according to specifications. So, this will probably be the first Pantanal 25 to sail.

Not far behind these two first units, the amateur builder Jorge Intashi just finished the hull and deck of his Pantanal 25. Jorge employed H80 foam and vacuum bag technique to ensure a high glass/resin ratio and managed to produce an excellent result.

The first set of plans of this new design was purchased by an Australian yachtsman, and then other plans were sold, mainly to Brazil, and to some countries in Europe. So we are looking forward to see the first Pantanal 25 sailing, and for this occasion we already have a bottle of champagne to toast the accomplishment.

Pantanal 25 interior rendered images.

Last year we introduced the trailerable sail boat Pantanal 25, a versatile cruiser-racer designed for amateur construction.
This design obtained an immediate response from the market and in a very short time we had builders starting to construct this boat in different places.
We have completed the design of the interior layout in 3 D rendered images showing in detail the amazing comfort of this arrangement.

Meanwhile the first builders begin to show their work. One of them, Barracuda Naútica, from São Paulo, Brazil, sent us photos of the plug they built to produce a mould for series construction, employing the infusion building method. This is good news, since we can be sure that this boat will be available commercially in the next few months.

Carlos Zanella Fichtner, from Porto Alegre, Brazil, is progressing at an impressive pace in planking his Pantanal 25 hull. Actually he is the first to send us photos of a Pantanal under construction, and they will certainly be a good incentive to other builders who are starting now.

Carlos employed light wood as core material, instead of PVC foam, and he reported us that he is not finding the least difficulty in planking his hull. In his case we suggested that he laid the planks attached by a tong and groove joint. He told us that the male planks fitted into the grooves without difficulty and that he had only to nail them to the moulds.

Another hot news from the class came from São Paulo, Brazil. Barracuda Náutica, a well known boat builder from that city, decided to build a mould to produce the Pantanal 25 in series. He will follow strictly the scantlings of the design, but for maximum homogeneity, they will employ infusion in their production. Click here for more information about the class.

Since we designed the Samoa 28, our state of the art boat for amateur construction, we were determined to produce the plans for a trailerable sail boat that could be trailed by a mid-sized car. The great advantage of this type of boat is the possibility of storing it at home, this way dispensing expensive marina fees. Besides, a boat like this can be launched in any locality where there is a boat ramp, which increases remarkably its usage scope.
Considering the profile of the persons who consulted us about the availability of trailerable sailboat stock plans, we arrived to the conclusion that most potential owners of a boat of this category are sailors with a small families, probably accustomed to high speed one-design sailing, who are looking for a camping boat of outstanding performance under sail which at the same time is capable of taking their families out for a coastal cruise in safety and comfort.
To make the boat the most attractive possible, we provided an interior arrangement with a cozy and functional layout. A double berth at the forward compartment joins with two settee berths in the saloon, omitting any partition that could jeopardize the feeling of amplitude inside the cabin. Abaft the two settees a heads compartment with door and a compact galley complete the saloon arrangement. A second double berth placed under the cockpit area provide full usage of space in the whole interior To prevent divorce claims, contrary to the majority of boats of this type, we assured a 1.70m (5'7") headroom in the main saloon, an acceptable figure regarding elbow room, if you have to stay aboard for a prolonged time. As the most requested area of the boat is the cockpit, we made it the longest possible, for that matter designing a practically vertical transom. We reserved the area under the cockpit seats abaft the double berth for storage of boat gear and other equipments. The Pantanal 25 is provided with a bulbous drop-keel, together with a pivoting mast, to simplify launching without neglecting stability
A boat to be stored in the home garden should be able to be constructed in its garage. Having in mind this possibility, the plans for the Pantanal 25 were defined to be built by the amateur, dispensing expensive moulds or special skills to accomplish this goal. The building method employed is the so called sandwich of strip-planking, using PVC foam or light wood strips as core material. The whole boat weighting only 1 000kg, including fin-keel, the Pantanal 25 is still sufficiently light to be trailed by a medium-sized car, an important factor to be considered.
But the main factor to be considered about the Pantanal 25 is its sailing ability. With a large roach full-batten mainsail and a good sized asymmetrical spinnaker hoisted from a carbon fibre bowsprit, our new design is capable of exhilarating performance.

How to build the Pantanal 25

The Pantanal 25 is specified for strip-planking sandwich construction, the so called speed-strip construction method. Preferentially she is intended to employ PVC foam as core material, but optionally PVC foam may be substituted by light wood, resulting in a heavier hull with a consequent small loss in performance, especially when under sail. This method of construction is easy and quite quick to be accomplished, resulting in a light and sturdy hull.
Sheets 0 which are supplied in CD, or, if required, printed in paper, contain the full size patterns for hull and deck moulds, as well as the full size drawings for the transverse bulkheads. Moulds and bulkheads when precisely cut by numerical control have their heights above the building grid correctly defined, so positioning them on it becomes an easy task. The CNC file supplied in CD allows the fabrication of the moulds by means of laser or miller cutting. If these processes aren't available locally, there is no restriction in resuming to the traditional method of cutting the moulds and bulkheads with the jig-saw. The smaller precision thus obtained is negligible regarding the final quality of the boat.

Label the position of moulds on the upper face of the building grid according to the following spacing:
The first mould is positioned at station 0.5. The fourteen other ones are placed at 480 mm intervals and the transom mould 400 mm abaft mould number fifteen. Fix the moulds in their places, taking care to match their positions, from first to ninth with the fore face of the moulds coinciding with the 480 mm spacing line and from there aft, reversing the moulds position. Beveling and fairing aren't required when proceeding in this way, representing an important saving in time of construction.
It's important to protect the edges of the moulds with an externally non-adhesive tape to prevent any spilled glue to stick to them.

Attach the moulds to the building grid, taking care to ensure that they stay plumb and perpendicular to centreline. Next install the stem base mould, which is also supplied in full size pattern and joins to the first mould. The stem is made with two pieces of PVC foam, being the one closer to the forepeak built with high density foam, since the forestay chain plate will be attached there. If high density foam is difficult to be purchased in small quantities, marine plywood may be employed in its place. After firmly fixing the moulds in their places, the hull is ready to be planked with the strips.

Prepare 60 mm wide strips from 15 mm thick 80kg/m3 PVC foam. (The width is reduced to 30 mm if wood is employed). Fix the first strip with its lower edge coinciding with the sheer line. Then proceed applying other strips until reaching about two thirds of the hull's girth.. Use temporary nails to fix the strips to the moulds and apply epoxy with filler (colloidal silica or micro sphere) to join their edges and ends. Then start applying the strips from centreline until reaching the ones that were already laid in place.

Once the boat is completely planked, the temporary nails are removed and the outside face of the foam is sanded to ensure a fair finish. Make a 2 mm rabbet with a circular sander on the 75 mm next to the sheer line to allow for the overlap of the deck lamination. (See detail in sheet 5B).
Now the hull is ready for the fibreglassing of the outside lamination. Employing epoxy resin to saturate the glass, apply two layers of 500g/m2 bi-ply material, overlapping 500 mm to the other side of the hull, this way duplicating in this area the thickness of the lamination. Finally the false stem at the lower tip must be installed. First bond a foam triangular patch already roughly faired to the lower part of the stem. Then, after the glue is set, carefully complete the fairing in place and apply over this patch the same lamination specified for the hull, overlapping the first layer in 50 mm and the second one in 100 mm. Sand the whole hull's surface after the resin is cured. When peel-ply is employed this is practically unnecessary.
Then apply an epoxy primer over the whole surface, except for the 75 mm rabbet next to the sheer line, since at this margin the hull is going to be bonded to the superstructure. Don't paint also the area around the bearing tube hole on the starboard topside, where the bowsprit will be attached.
When this task is completed, it's a great occasion to call the close friends for a barbecue, since it's time to turn the boat upside.

Remove the moulds after turning the hull upside. Then sand the interior and remove with a chisel the foam at the central area where the keel case will be attached, and also a patch where the shrouds chain plates will be installed. The lamination is single skin in the keel area and reinforced where the chain plates will be fixed. On that spot high density foam is inserted to reinforce the chain plate region. Before inserting the high density foam it's important to apply at the shroud chain plate location where the foam was removed two rectangular patches of cloth on the bottom of the rectangular hole opened there, laying on the inner side of the external lamination. Then apply two other cloth layers overlapping the hole walls which should be chamfered. Only then insert the high density foam and apply the inside secondary lamination. (See detail in sheet 5A). If wooden strips are employed there is no need to remove the strips, but it will be required an extra external secondary lamination over the hull's outside lamination.

Building the interior

Once the internal lamination is completed, the next task is the installation of the keel trunk, floors, bulkheads and furniture partitions.
The keel trunk, a rectangular box with rounded edges, is made over a male plug. The easiest way to make it is to apply the first layer of lamination around the plug and cut the after face vertically with a sharp edge tool. Then open slightly the laminate, remove the plug and proceed with the application of the remaining layers of lamination. After installing the keel Delrin or UHMPE (ultrahigh molecular-weight polyethylene) bearings, the case is ready to be installed. Apply the secondary lamination specified in sheet 5B to bond the keel trunk to the hull bottom. After doing it, open the hole for the lower bearing. One way to make it is, after marking the rectangular area to be cut, to open four holes, one in each corner, and cut the rectangular hole with a jig-saw. There is no inconvenience if the cutting line isn't absolutely precise. If a small gap is left it can be filled with epoxy putty as far as the keel trunk is correctly positioned. The bearing slot for the fin-keel must have a 0.3 mm maximum tolerance at each side, to prevent undesirable noises when the keel tilts.
Floors are installed only after the keel trunk is firmly fixed to the hull bottom. Prepare the shape of the floors with rigid polyurethane foam and encapsulate them with the lamination specified in sheet 5B. Finally install the PVC foam sandwich brackets which join the floors to the keel trunk, as specified in the plans, attaching them with secondary lamination.
Next the transverse bulkheads, which full size patterns are given in CD, are constructed in sandwich over a lamination table.
Carefully mark their positions on the interior with a pilot pen and fillet with epoxy with filler both sides of their edges. When the putty is cured, apply fibreglass tapes according to information given in detail in sheet 5B.
The remaining furniture partitions and the anchor rode well are made in a similar way as the transverse bulkheads, except that for them there aren't full size patterns. When finishing this work the interior is ready for the finishing work. The apparent edges of all bulkheads should be covered with a light cloth tape and then the whole interior is ready for sanding and to receive the finishing paintwork.

Building the Superstructure

Once again the moulds are fabricated by laser or miller cutting. They are also assembled over a rectangular grid, which in case the hull and the superstructure aren't built simultaneously, may be the same one.
The deck is built in a similar way to the hull, except that instead of strips it's employed foam panels. The radius between the trunk coach roof and the sidewalls is too small to allow for foam panels to bend over the moulds. On that place it's necessary to apply foam strips, as were employed during the hull construction.

When putting the foam panels in place, the bonding of a panel to another is made with sharp angles. The concave angle is later filleted according to the radius specified in the plans and the convex one rounded to specifications with a sanding tool. (A surform plane or a pad with sandpaper are quite adequate for the job, but with skill and some care, an electrical sander may also be employed). Only then the secondary lamination is applied. Insert high density foam, or, if not available, marine plywood patches, where fittings will be installed. (This is shown in sheet 5A.)
The outside lamination is applied after fairing the foam. When the fibreglassing is concluded, the whole superstructure is sanded. Then the deck is ready to be turned turtle for the inside lamination. Again round the convex edges employing a sanding tool and fillet the concave ones with epoxy with filler. The inside lamination is applied in the same way as the outside. After sanding the internal surface, cut the lifting-keel beam foam core and bond it to the ceiling. Then laminate it integrating to the superstructure.
Following, the hull is bonded to the deck. When lowering the deck on top of the hull, the bulkheads will fit very close to perfection under it. If in any particular point bulkheads and superstructure don't fit as a glove, if it's left a gap, this will be filled with epoxy putty, but if there is a lump instead, this lump requires to be removed with a surform plane, rasp or sanding machine.
First bond the topside edges to the underside of the deck, employing the same epoxy putty used to join the foam edges. Next fillet the inside edge all around the boat and apply the internal deck to hull secondary lamination. Then fillet all bulkheads to the superstructure and apply the secondary lamination tapes at their both faces. Finally make the round radius specified along the sheer line and apply the hull-to-deck joining lamination, overlapping the topsides lamination along the 75 mm rabbet
The bowsprit bearing tube is fixed at this stage.
Only after applying the finishing coat of paint, systems, fittings, drop keel and rudder gudgeons are installed. Next step is to invite your friends for the first trial.

Dear Roberto

Very many thanks for the study plans. I have been out on site for the last two days so have only just opened your email. I like to study plans for a little while just to familiarise myself but the plans are excellent and I have no concerns. I certainly do not profess to be any sort of expert but I have so far built 5 dinghies of various sizes and construction (sailing catamarans, dinghies and my last one is a canoe (sailing rig when required). I have just finished building two outriggers for my canoe for when I sail it in winds above force 3-4, a somewhat hairy experience!!

I am very impressed not only with your website which I find to be informative, inspiring and easy to navigate around but also with your plans. I am honestly really excited about the prospect of building the Pantanal 25. Would it be possible to send me the building manual as well, it would be greatly appreciated. I need to sell my current boat, one I did not build myself, so I can start on this project. She is 22ft long, somewhat slow but a great sea boat. However I begrudge the charges that I pay to the boat yard for winter layup and have to travel a 60 mile round trip to carry out maintenance!

It's fortunate that I came across your website as although I had already decided to build a trailer sailer, the design I had chosen was very much a compromise and although I love building boats and sailing them, it was not really a design that I had tremendous enthusiasm for but it was the best of an indifferent bunch of designs.

I love the lines of the Pantanal 25 and can already visualise the admiring glances that I know she will receive, even better to build her myself and the joy of sailing her.

Sorry to ramble on! Look forward to hearing from you .
