As with any
used boat, do an objective look over yourself and get a good
survey.
My experience as a moorings owner who has also traded time on many of their
boats, is that their
boats are well used, but also tend to be fairly well maintained.
To know about dockage and
documentation, it would be helpful to know where the
boat is located, what country it's currently registered in and what country you wish to register it in. Many of the Moorings boats in the BVIs are U.S. flagships.
