seek advice on offshore cruiser
A great place to look for a boat is at a marina with a yard full of boats. There''s a good one on Virgin Gorda.
I would think that if you vacationed in the VI and BVI and traveled to the various boat yards, talked to the yard managers and employees, you might be able to connect with an owner that would be happy to sell their boat as is, where is, for the right price.
Don''t know if there''s a sales tax in the BVI. Eric on Kimberlite would be a great source of info for this sort of thing. He lives on St. Thomas, I think.
St. Martin has a decent yard as well, as I remember. I looked at boats there many years ago.
