2021 Map of Head of Westport OE S

About this map

Atlantic Ocean waters dominate this modern hydrographic study, where the maritime boundaries of Massachusetts and Rhode Island meet. The survey delineates several significant undersea hazards and rock formations critical to local navigation, including Twomile Ledge and the curiously named Old Cock. Near the shoreline at the top of the sheet, the northern terminus of W Beach Rd marks the only terrestrial infrastructure, providing access to the coastal margins where the Rhode Island Sound begins. Farther offshore, the map traces the southern path of the Intracoastal Waterway as it passes through open water. For researchers of coastal history, the map provides precise locations for offshore landmarks like Inner Mayo Ledge and The Wildcat, which have historically defined the maritime approach to the Westport region.
