If this boat was glassed in and overturned, people would have found it impossible to swim out of it with a life vest on. You simply can't swim down with a life vest on... and it'd be difficult to find the exit regardless. So it may be a moot point. But don't let practical application stop you from nanny-stating more rules about things you've never done! People do it all the time :~D
