I think you can argue that more or less weight is faster under different conditions. My personal opinion is that lighter boats are almost always more fun to sail. Is an A class cat faster then an nacra 5.5 uni? Yes. Is it more fun to sail? Hell Yes. Is an F18 HT faster then a F18? Most of the time. Is it more fun to sail? You bet.
I am done sailing overweight beasts.
