Weta Trimaran was awarded Boat of the Year by Sailing World magazine. There are two distinct builds of the Weta Trimaran, the 'original build' and the '2015 Weta' which was created from a new mold and included (mostly internal) hull revisions. In April 2017, Weta announced the availability of a foam-core Weta which was 12 kg lighter than the Standard boat which is still available. The foam core boat is right on the minimum weight in the class rules. From 2006 to 2014 the 'original build' was manufactured in China for Weta Marine and sailed internationally with 1000 boats sold to date
Pontoon effect a trimaran with narrow-beam floats will simply submerge the lee float, exposing only the weather wing and that with a lesser moment. In practical sea situations the windage effect is greater than the buoyancy effect and so cruising trimarans with highly buoyant floats are more, not less, likely to capsize than those with less buoyant floats. A trimaran is best stabilised not by adding buoyancy on the lee float but adding weight to the weather float. This is the basis of the "cool-tubes" stability system invented by Tristan Jones and L. Surtees. A large-diameter pipe closed at the aft end
