I wonder why they wouldn’t have stayed with the boat......
They may have tried but the hull is smooth by design for efficient running and not for hanging on.
If the got flipped over who knows, could have been knocked out banged up.....weird stuff goes on out there.
No answers is the hard part and may never be.
The hull may show signs of scratch marks or indications of someone trying to hang on?
If you ever get a chance to talk to a coastie that does SAR the stories are endless and unbelievable.
