The only real danger is if you are knocked out when you flip but a crash helmet would prevent that.

Obviously you would need to be seated for this but most smaller racing powerboats use seats - not bolsters. In fact looking at typical RIBs it seams their CG is way too high.
Harnesses are only allowed on canopy boats - all open race boats cannot have harnesses fitted. Canopy boats are also required to have seperate air supplies for both of the crew and many are removable when you exit the boat you can take your air supply with you.

There is also a requirement to practice being turned over in a swimming pool with blacked out goggles on before you can race in a canopy boat (a "dunk test").

Even in the race ribs with rally / race seats crews can get thrown out if the boats hook violently enough, but there again I have seen batboats and others eject thier crew as well!

Which is exactly where a harness comes in! I can see the logic in only allowing their use on a canopy boat but a full face crash helmet would give a bit of protection - surely being thrown out is more common than a flip?

Then again maybe passive protection - ie plenty of grabrails and footstraps etc would be the way to go.

On helicopters operating offshore a safety cert is a must - one of the tasks involves releasing yourself from a harness upsidedown in the dark under water!

Nah Use footstrps to keep yourself in and if it's too rough for that then slow down

My opinion is that you really really don't want to be strapped into a boat with no canopy upside down! I still can't understand what the benefit is?

If you are doing 40 mph and the boat rolls on a turn (most likely scenario) you will get your head ripped off, wated forced everywhere it isn't meant to go and then you have to find the release buckle before you run out of breath!

One more thought for you - have you ever seen any sort of seatbelt or harness arrangement in an open boat? I know I havn't and I think it is probably because all those you thought about it decided it was a bad idea!
