The CSX would NOT do well in 3-4' waves. Good luck just getting out of an inlet with 3-4' waves rolling in. Like Ted does with his wakesetter, you could take it to the reef in the keys, but do your homework on the weather first.
The CSX is a bay boat, not an ocean boat. It would be a fantastic boat in the intracoastal, or tampa bay, etc, but I know I wouldn't take it out on the open seas, except for a calm day.
I really am not trying to bag on the CSX, as we have seen it has a phenominal wake, just really don't want people getting into bad situations, thinking this boat would be good in big ocean waves.
It is definately possible to ride behind a good fishing/dive ocean boat such as a Contender, Pursuit, Jupiter, etc, and reasonable wakes can be had with these boats. Probably not as fun to drive pulling a rider, but definately possible.
Ted, if you are adding to your fleet keep the wakesetter for wakeboarding and get a 32' Contender for fishing and diving, and make sure to invite me a lot. haha
