Just received my new hull and my boat is now a pound under! Yay! Considering we sail at 385 it's nice to have a light boat but that being said we sailed worlds, catacup and several other events and it didn't bother me that the hull was 11 pounds heavy. And ahpc did the right thing by replacing our hull at no cost to me.
Rod Waterhouse had a heavy boat at worlds and he won a race. I don't know who else had heavy boats.
