The BVI has a very active market on used boats, with a lot of Sunsail/Moorings charter
boats but also many others on the market. There are several professional brokers and access to the boats for viewing and survey

If your target buyers are French then St. Martin, Guadeloupe
are good choices.

when I was searching for a boat and believe it is more of a niche market (lots of Oysters, for example) than the BVI.
