i think we all know that all realise a rounded plaining hull is more efficient that an v deep one but as v deep ones such as a quattro or a pixie are so much easier to homebuild i was wondering

for a boat with the same rig how much slower how many points on a handicap system would a v deep hull be

or alternatively how much extra sail area would you have to put on the to make say f14 type cat to make a v deep hull go as quick???
