About this map

Maritime hazards and deep-water boundaries define this coastal survey off the shores of Bristol and Dukes counties. The landscape is primarily aquatic, dominated by the Rhode Island Sound and the open expanse of the Atlantic Ocean. Submerged navigational features such as Twomile Ledge, Inner Mayo Ledge, and the colorfully named Old Cock and The Wildcat indicate the treacherous nature of these waters for mariners navigating toward the mainland.
