A stingray you say?
Never seen one.
What is that, a 4 foot beam?
I DID like the underwater footage.
The boats boats I've been on turtled, luckily always recovered by getting skip and crew on the lee most stern.
I guess that if you knew the mast was not going to recover, as in full of water, taking it off might be as possibility, I don't know that I'd have done it though.
