And that $6/day cruising tax is for charter boats being chartered within the BVI. If you bring a charter in from USVI I believe the tax jumps up significantly but I cannot recall how much pp per day.

If not chartering but cruising, I have no idea what the cruising tax is. Would be interesting to find out. If it is too high, it will scare off long term cruisers as it will become too expensive for them to cruise and stay in the BVI waters.
