See if you can install a training boom for ease of learning. This should fit on your new ski boat.
This is a great way to teach your kids ( or adults) to ski or wakeboard.

The boom consists of a long, metal pole extending from the center of the boat (usually connected to the ski pylon in inboard ski boats) over the water opposite the boat driver. Wires also extend from the tip of the pole to the bow of the craft for added reinforcement.
