Generally Wake board boats have water ballast aft to increase the size of the wake for tricks. I think that you can buy one of these bladders and experiment to see what wake and how much ballest you can safely carry.
I suspect that even with full ballast, that the wake will be less than a wake board boat.
The second problem is the lack of a tower. The tower puts a towing position up high (to keep the rope from fouling the cockpit, plus allowing the boat to track without being pulled around by the wake boarder. You can ski behind a C Dory; best done with a bridle and pully on the bridel. This same trick could be used with a wake board, but the tricks woould not be at all easy, because the rope is low to the water, and the wake boarder would pull the boat around.
I hae solom skiied behind 25 hp--so you can do any water towing activities with low hp--but it will not be the most effective.
