I stuffed a 22' raceboat once. It was a relatively gentle stuff, just took the top off a wave really, but we were going just under 70mph and I remember the water coming up the deck as I thought "oh balls". Had my crash helmet open just a crack to stop the visor misting.
It wasn't a hard stuff, so the boat didn't stop too hard, but the water hitting the visor impacted it on my nose, before the visor disappeared off overboard somewhere. Properly broke my nose though.
I reckon a proper, high speed, hard, stuff, is one of the most dangerous things, both to people and to kit. Spinning out, even barrel rolling, capsizing, all sorts, it's less of a hard impact. So while there other survivability issues with those, a stuff is just nasty.
The thing to be mindful of on ribs is once you're going at a decent lick, the pressure of the water is higher than the pressure in the tubes, so they'll start to offer little in way recovery "during the moment".
As always, drive to the conditions, your kit & your ability. I broke my nose by driving in excess of my ability.
