I watched this video and thought it was very measured and frank and I believe his motivation in alerting others to the pitfalls of learning about salvage after the fact. I thought his decision to give them the boat was a reasonable one given the situation. Probably would have been even better if he'd done it before shipping to FLA.
I don't know that I'm up on salvage law myself, but I'm sure it is a big risk especially if there is no insurance. I'm willing to bet when the insurance company pays the salvage bill it looks a little different. I've often read that you should throw the other boat your line when towing, not accept their tow line... no doubt there are bad surprises and pitfalls in these aged laws.
He did complain at one point that the insurance company sent someone out and they never looked at his boat but went out to look at the mooring balls.
