Pop 25
European Union Stability Index
According to the stability index adopted by the European Union ( STIX), which evaluates the seaworthiness of mono-hulls, the Pop 25 belongs to category B, which means that it is adequate for offshore passages in accordance with the specifications below:
Design Category B ~ 'OFFSHORE'
Designed for offshore voyages where conditions up to, and including winds of wind force 8 and significant wave heights up to, and including 4m may be experienced.
It is important to state that most production yachts of her size aren't capable to comply with this category. Next we show a summary of the calculation and the STIX number for the Pop 25
STIX Pop 25 = 30.1 – Category B
