two jokers out at mid-town, with a jetski and Bodyboard, at low tide?

i was on the beach watching and it looked like the guy being pulled, got his arm yanked out a couple of times.

you might be bored,.... but it looked like you would want to pratice so much before ever trying to do any tow-ins, or tow-outs/ats, or whatever with a jetski

Anyone have any thoughts about it?

Other the backwoods crew, no one else really doing anything around here.
