Thanks for all the warm wishes everyone.
@Khagan1227 The point about them not being able to transport it without permits is something I considered. He has a support person who seemed to be getting permits for each state on the fly as he crossed the country. That's how they operate since they tend to adjust their course as they go. Neither I nor the maritime attorney I called knew that they would not be able to get permits to take the boat to california
if there is a dispute over it. He really tried to make it clear that he wasn't bluffing and would have no problem getting permits to take the boat there and was willing to pay the relatively small expense to have the boat offloaded into a yard in California
The thing I was weighing was the cost of having the boat transported from Cali vs the extra $3K. I think he had calculated this as well.
Blocking his truck with my car wouldn't have gotten my boat into the water
But you make a lot of good points about things to do to avoid possible issues.
Deal with trustworthy people is my number one piece of advice, because if someone isn't going to honor a contract
, it is just a piece of paper.
