Absolutely go try it. Lots of fun, as much as snowboarding, but in a different way.
Similar enough to snowboarding, much more like being in wet powder or slush. Lean on your back foot a lot more than you ever would consider good form on a snowboard.
I've pulled many many never-been-on-anything-that-slides-on-water, frozen or not. All of them were up and riding on a wakeboard in a handful of tries. Many who had other experience (snow, waterski, skateboard, ice skate, any kind of balance on moving platforms) were up and riding in 1 or 2 tries.
