Thanks everyone. I'll definitely check with the charter company (Moorings) when get I there but I wanted to plan my itinerary ahead of time if possible. It looks like the clearance fee for the week is $20 which is what I think I paid in Anguilla for one day so I suppose it's not so bad.

Thanks also for note about having life jackets in the dinghy. We never even think of taking life jackets when going ashore.
