I have a skiff and around 30 mph the bow sucks to the water an starts to hook the boat. Its a trihull whaler style boat.i added ply wood behind the transome to give set back but i cant get the prop to bite enough to over come the hook in the hull. Its manual trim 20inch motor 20 inch transome. 11 1/4 x 16 ron hill prop anti cav plate top of plug hole.

Im thinking about cutting and redesigning the back half of the hull. Any imput? I also thot about adding three small pads.
