SeaCart 30 Trimaran SeaCart 30 Trimaran The SeaCart 30 is a trimaran sailboat. A trimaran is a multihulled boat consisting of a main hull (vaka) and two smaller outrigger hulls (amas), attached to the main hull with lateral struts (akas). Since 2005 when the full carbon one design SeaCart 30 GP (Grand Prix) (SC30 GP) offshore Trimaran was introduced performance sailors have been enjoying flying two of three hulls. Rudders on the amas (pontoons) make handling swift and precise. The ultra light strong carbon construction and a non existing interour (can be added) plus extra large sailplan make the carbon GP model a
Pontoon effect side than the center of buoyancy can go. At this point, the righting force will disappear, replaced by a turning moment in the opposite direction. This can capsize the vessel at the point at which one pontoon is completely submerged. When using twin lateral pontoons, each pontoon should have enough buoyancy to bear the load of the entire vessel on its own. If the vessel is so heavy that either pontoon is mostly submerged when no lateral force is applied, it will be vulnerable to the pontoon effect. If sufficient lateral force arises (such as wind or shifting load), the
