As Robert Heinlein once said, "TANSTAAFL" and I should have said, as sail2wind corrected me, that there is no individual fee to be paid for using the mooring balls off Tintamarre. The mooring balls there are maintained by the marine park service and once is allowed to use them for overnight stays. The St. Barths moorings in Tintamarre and Colombier are maintained very conscientiously by St. Barths and are indeed partially funded through the clearance and overnight costs.
