2013 Map of Plum Island OE E

About this map

Great Gull Island and Little Gull Island anchor the western edge of this maritime study, positioned where the Long Island Sound meets the Atlantic Ocean. The area is dominated by the treacherous waters of The Race, a high-velocity tidal strait known for its underwater obstacles such as Race Rock, Valiant Rock, and the submerged Race Point Ledge. This 2013 survey illustrates the complex nautical environment off the coast of Suffolk County, documenting the specific hazards that have historically challenged navigators in these eastern Long Island waters. A single transit line, the New London-Montauk Ferry, cuts diagonally across the open sea, connecting these coastal regions. Farther south, the isolated Constellation Rock sits alone in the deep water, emphasizing the sparse but critical topographical landmarks that define this stretch of the Atlantic.
