Kevin is correct about hurricane season. Most boats are taken out of the water or moved to a safe harbor (often in the Grenadines) or dry docked on another island during hurricane season. In St Kitts they put sailboats in large holes in the ground with the deck flat to the surface and the mast well secured.. they put old tires in the hole around the boat, seems to be a good system, although some people prefer a dry dock system where they can work on their boat in the off season. St Martin used to do a lot of that but after some of the recent hurricanes, where hundreds of boats were destroyed on land and in the lagoon, I'd think twice about that. The director of the port in SBH is Ernest Brin, and as Kevin notes, speaks quite good English. To my knowledge there are no year-round moorings currently available in the inner harbor... but it can't hurt to ask, might depend on what kind of boat you are thinking of bringing...
