Ok, I know this sounds nuts. But since I cut down the swim platform I can visibly see these chines causing wash and disrupting the wave. So I talked to my local fiberglass shop and turns out he did this to his old ski boat to improve the wakeboard wake. According to the engineers the are left over from water ski days, and their new surf boat actually doesn't have them (I like to believe I played a role in that
. They are called chines. My biggest question is does anyone know why some boat manufactures have a small flat area in the corners of the transom? I know MB, Centurion and sanger all have them. Here are some pictures. I am not expecting a giant change but hopefully a nicer wave. Also the chines cause lift so cutting them should allow me to run less weight and get the same wave. So do I make them just a sharp angle like the new Tige z3 and the malibu 247 or put a flat section in like mb, centurion and sanger?
