I'm curious as to how board sports would be behind this boat. I have the much smaller 14.5' version, and I found that it makes pretty rough water with the jet. It's smoother the further back you go, but if you're trying to surf, you have to be right up on it. I think those giant wake board boats have special plows they deploy for surfing. Not sure that's even possible as you have jets, but I also am not sure how and where those things mount up. Wake boarding should be pretty good though, as you can get far back enough to ride the smoother water. Also, this beast should put out a decent wave.
Another issue I have with my boat is it's hard to dial in the correct speed. 18mph is about the right speed for wake boarding, but at that speed, my boat starts to get on plane. One on plane, it quickly gets too fast, and if you slow it back down, it falls back in the water, where it goes too slow. Took my wife and I a while to get good at controlling it to stay at that sweet spot.
As for pulling, man, the amount of thrust you have, you can pull another speedster and get it up on plane.
