Today was probably the best sailing day this year. For the first time we raced my 18 ft A-Cat vs 18 ft trimaran. We started out with two frozen boats, but in the sun it felt like any Swedish summer day :-). I installed one action cam on each boat, plus some mobiles. Now you can compare 18ft cat vs 18 ft tri.
In the light wind, the tri felt faster as long as the A cat had both hull in the water. When it was more wind and was flying on one full, the trimaran lost the fight.
