Well just getting into this wakesurfing deal, i have a hyperlight 5'6" wakesurf and a 1998 nautique super sport/ AIR. as far as ballast i have a 250 on each side of the motor and a 600 in the ski locker, this is my wakeboard setup anyway. I am not looking to buy more sacks so just want to work the best wave i can with what i have. We have surfed a little behind my roomy's mastercraft and seem to be getting decent wave there, but on my boat we have had no luck, i am putting everyone on the left side rear and just cant get the wave to form anywhere from 9-13mph. I'm looking for help and advice to get me going in the right direction! Thanks in advance.
