I would suggest that one review the allowed sailing area in the charter contract. Depending on the term of your charter you will need to account for the customs issues, clear out of BVI, clear in to US, clear back in to BVI. Though I have not tried this with Moorings/Sunsail, I have seen other contracts that limit the sailing area to no further than 5 miles south of Norman, and no further south than Cruz Bay, St. John.
