I think you are a hypocrite and "instigator" is very fitting under your user name. And why talk about it now since in your words "the general internet public won't know the answer". BTW, obviously the windshield is part of the canopy. sheeesh....

nobody has addressed the fact that in all instances the plexi/lexan/whatever/ windscreens imploded on impact,,, the resulting incoming water pressure and volume THEN tore the canopy away from the supports
you don't see aircraft windshields doing this when they hit rain at 400-500 mph....
which begs the question, what thickness or mil rating is the clear glass/plastic/lexan/whatever?

But yes, it should definitely be in one piece after that "little" incident.

I have seen bird's enter helicopter cockpits at low velocity though...
I guess my basic simple question is > does the current offshore sanction bodies have a windscreen spec for thickness/composition/material for open or enclosed cockpits?

I spent several years as an aircraft mechanic at MIA, and worked flightline damage repairs daily, and 3 or 4 direct runway crashes, I never saw a windscreen that *tore* away like these did, we did have heavy hail and bird damage, but not a *tear* situation...

The HANS device was invented to prevent basilar scull fractures. A fracture that occurred in formula cars, high G accidents, with a very reclined seating position and heavy full face helmets. Conditions that put a lot of strain on the base of the scull.
Offshore powerboat accidents are usually moderate G accidents, upright seating, and lighter helmets.
Are basilar skull fractures a common problem in offshore racing? If so, HANS or other head and neck restrains should be adopted by as many as possible.
If not, the risk of the HANS getting stuck when evacuating should be considered.
Just my 2 cents.

Yes they are somewhat common. Bobby Saccenti had one for example in the Apache cat back in the day.
Do not recall the death causes of Mark Lavin and Stefano Casiraghi but wouldn' t count it out.
Theres little risk in a Hans getting stuck when evacuating IMO. It hasn't been a risk in racecars either where fire is always a threat. Once you get used to wearing it you do not even notice it racing.
