Re: MOB systems
I tell my sailing students that one of the best reasons to learn the bowline is to make a loop to get under "Oscar's" arms, then to a halyard that can be led to a winch.
Or to tie a halyard into a lifesling if there is one.
Also many sailing books don't teach the quick-stop, but only the figure-8. Given the time and weather, I try to teach both.
