dshaff for boarding you want to weight the boat evenly, but for surfing the point is to make the boat lean to one side, called 'listing'. One 750 sac along the engine on the port (passanger) side does the trick.

Larry Thanks for dropping by, hope you arent getting to many alerts from me hehe! I am very very very tempted to try out your surf skate and I ALMOST bought your combo offer for both boards.
