Pop 25 Solaris - A silent revolution is coming | Part II
No sooner did we publish the last article about the Pop 25 class in our news section, and an impressive number of fresh news fell into our email-box. It seems that during this fortnight the class gathered momentum and is finding its path towards becoming acclaimed as a break-through in cruising sailboat amateur construction. In the mean time our builders with blogs in the internet have made important progress, now having their hulls sheathed with fibreglass, getting ready for the turning over.
Mandala, the Pop 25 being built by Marcelo Bonilla, is the most recent construction to be started. At this point her builder is beginning to sheath the hull with plywood panels. This construction is an example of precision. All the transverse structure was fabricated with CNC equipment. Photo: Marcelo Bonilla.

Meanwhile we had been acquainted with a little marvel in electric auxiliary propulsion, the plainest thing we have seen yet, having everything to do with our endeavour of simplicity. This is the new electric saildrive motor, by GreenStar Marine! The price may be a bit salty (9900 EUROS), however this motor is a consumption dream for any Pop 25 owner.
GreenStar SD10. Perhaps the most compact electric auxiliary in the market
This is the GreenStar Marine publicity about their new product:
“Modern design, lightest weight on the market, easy to install and almost maintenance free!
GreenStar SD10 is comparable to a 10 hp diesel engine. The motor is very compact, easy to install and almost maintenance free.
However, in respect to innovation, the Pop 25 is Jack of many trades. We had quite ambitious plans in mind before starting the design. We wished to produce a survival cell capable of standing whatever being the challenge, this requiring to be achieved in the most self-sufficient way possible.
Probably the most appealing characteristic of the design is the capacity to rest on the bulbs of its twin keels, bringing bottom maintenance in ebb-tide within the reach of her crew. The high costs of hauling up make this possibility of independence from boatyard servicing being a decisive factor for owning a Pop 25.
The Pop 25 story is that of an unsinkable boat that can sail indefinitely without depending on fossil fuels as source of energy. It is also the story of a boat that can be tossed about in the wake of the fiercest storm without its crew being afraid about the integrity of its structure.
Another outstanding feature of the project is its built-in thermal insulation. The Pop 25 building method has a unique specification for its hull topsides and superstructure. With the climate changes that are coming in sight, bringing with it a menacing global heating, a proper thermal insulation is becoming an issue that can’t be left in the background anymore, especially in the case of smaller crafts. With this worry in mind we endowed the Pop 25 topsides, deck and coach-roof with double-walled structure, ensuring efficient thermal insulation just from the construction phase. These foam-filled structures make the Pop 25 resemble an authentic cool-box. Since natural ventilation is also well-sought in the project, the boat is well protected against condensation and mildew, besides being cool in the tropics, and warm internally in higher latitudes.
The Pop 25 is comfortable enough to be used in long range ocean passages. Her built-in thermal insulation makes her adequate for being used in the tropics or in high latitudes.
However, there is a feature that makes the Pop 25 a break-through in amateur construction; the speed of building its hull. There is no sympathy for constructions that take ages to be completed, and when the boat is launched, the owner, who was a young person in the beginning of the construction, is already silver-haired. This scenario is being proven not to be the case with the POP 25 construction. Our clients who made blogs telling their experiences are reporting that, after completing the fabrication of the transverse bulkheads at the workbench, an easy job to be accomplished, two months are enough to assemble the hull ready for being turned over.
Solaris, the Pop 25 being built in Rio de Janeiro, is a good example of this. Just have a look at the photos below:
A little more than two months ago Solaris construction was in this stage. John Matheson, the one in white T-shirt, is building the Station 4 transverse bulkhead, which he found out to be a piece of cake to be done.
Polaris stage of construction one month later. It was still missing saturating the whole topside structure with epoxy and filling the spaces between nervures with Styrofoam, the next step in the construction being fixing the topsides external walls.
It took two days to plaster the hull with practically no fibreglass sanding required.
Now, just two months after assembling the bulkheads on the building-grid, the hull is already plastered and is almost ready to receive the first coat of epoxy primer. The turning over is scheduled for December. Since all equipment, including the electric motor, is already purchased, it will not take long for Solaris to be sailing.
