Matheson Hammock Marina is one of the most popular marinas for both boaters and those looking to enjoy the waterside in this tropical hammock. Dock here and enjoy a full-service marina complete with Castle Harbor Sailing School, for sailing with the pros. Take a dip in the man-made atoll poll which is flushed with the tidal action of nearby Biscayne Bay. Have a casual lunch at the snack-bar or a first-class dinner at NOMA Beach at Redfish.
