There's also another great forum you should check out - Travel Talk On Line (TTOL) -- there are lots of great people there and an entire section dedicated to the BVI. We chartered via BVI Yacht charters last summer and my husband and I sailed a Beneteau 40CC "Trinity" -- terrific boat, very easy to sail for 2 and a HUGE, comfy aft cabin! Loved her. She's owned by a TTOL member and handled via BVIYC -- made it easy to ask questions about her, etc.
Just food for thought
