Description: Completed in 1959, the main harbor is one of the island's two deep draft harbors. Coral dredged from the harbor basin and entrance channel was deposited on the south side of the harbor, creating a massive landfill and stockpile of soil material. Further erosion of the landfill has created several beaches within the harbor. It is frequented by yachts, commercial freighters and small whalers.
