That guy's jet looks too heavy (thrust vs. weight) to take on extremely aerated water. The video edit is great, but I'm sorry, they look like a bunch of frat boys out for a good time. Tackling water with serious consequences like that, I'd expect more of a clinical approach--someone who approaches their sport like Kirby Chambliss (Red Bull air racer.
The Kiwis have been doing it for decades--if they can do it, it's possible.
...but I would think he'd need this kind of thrust to weight:
The motorhead in me says it's awesome.
The river runner in me worries about a spill.
The Libertarian in me says he should post a bond against cleanup and recovery and go for it.
