I have heard the same thing about waxing the hull. It actually creates more surface friction. On another site they describe rubbing your finger across a piece of glass - it sticks and squeaks as it goes across, however, a peice of wood sanded with 400 grit paper will be as smooth as silk. Those microscopic scratches/pores in fiberglass actually collect air at high speed and cause the boat to glide. When you wax it fills those in creating an ultra smooth/sticky surface just like the finger on the glass analogy. High perfromance racing boats actually scuff the bottoms with a high # grit sandpaper to add speed. So buzzking is dead on Don't wax that hull, especially if you are trying to add speed.
