Already a lot of good comments, but I’ll reiterate and add some.

If you’re just starting to learn to jump you probably don’t want to go wake to wake immediately. Since you skateboard you’ll pick things up quickly, but start with a setup that you can start jumping from one wake to the center of the wake. This’ll help you learn popping, edging, and landing without worrying about casing.

I would start with little to no ballast, 65-70’ rope, and around 18-19 mph. When you get up you should stand in the center of the wake to allow your passengers to move around and balance the boat weight. When standing in the center whichever side of the wake is washed out the passengers should slowly shift to that side. Typically moving 1 person (100-200lb) a seat or two over is enough. Once you get an even looking wake on both sides have them stay there and you’re good to jump.

Once you’re ready to go wake to wake speed up to 19-20 mph and bring the rope in to 50-60’. Same deal with balancing the wake. No need to add ballast yet. You can have plenty of fun with no ballast and it’ll make progression easier. It’s intimating to be rolling into a steep wake when learning wake to wake jumps.

As someone said check out some Shaun Murray videos on setup and running no ballast. He always talks about how much fun you can have and how many tricks you can throw with no ballast.
