> it dawned on me that waterskiing is done on a single ski

Isn't waterskiing on a single ski called wakeboarding? Where I grew up in Florida plenty of people waterskiied on 2 skis.

You learn on 2, then move to 1 aka slalom as you have far more manuverability.

Wakeboards and skurfers (if those are still around) are wider than a slalom ski and don't have both feet facing forward. They are closer to a snowboard.

But I find the most fun behind a boat is on a regular surfboard.

There are single (slalom) water skis, they are different from wakeboards.
