Montauk Harbor, in the northern part of Lake Montauk, is entered through a dredged channel on the northern shore about 3 miles west of Montauk Point; a Federal project provides for a depth of 12 feet in the channel and 10 feet in the boat basin northwestward of Star Island. The entrance is protected by jetties, each of which is marked by a light. A lighted bell buoy, about 0.3 mile north of the entrance, marks the approach to the harbor.
Star Island, just inside Montauk Harbor, is connected to the mainland by a causeway. A private light is shown from the eastern side of the island. A privately marked channel, with a reported controlling depth of 7 feet in 1999, leads from beyond the end of the federal channel to the southern part of Lake Montauk where there are depths of 6 to 8 feet in the center.
There are several small-craft facilities on both sides of the entrance to Montauk Harbor, and a yacht club and several marinas are on the east side of Star Island. Gasoline, diesel fuel, water, ice, marine supplies, and space for transients are available. Lifts to 80 tons can handle craft for complete engine and hull repairs. Groceries and other supplies may be obtained at the village of Montauk.
