| Description: | Port Jefferson Harbor, on the south shore of Long Island Sound eastward of Old Field Point, is entered through a dredged channel that leads between two jetties to a docking area near the southwestern end of the harbor; the jetties are each marked by a light. The approach is marked by a lighted whistle buoy, about 1.1 miles northwest of the entrance. Two stacks on the west side near the head of the harbor are conspicuous landmarks. A 12 mph speed limit is enforced in the main entrance channel, and a 5 mph speed limit is enforced at the head of the harbor in the vicinity of the mooring areas and wharves.
Mount Sinai Harbor, 22.5 miles westward of Mattituck Inlet, is marked by a low break in the beach nearly 1 mile long. The approach to the harbor is marked by a buoy. The entrance is protected by two jetties, the outer parts of which are awash at high water. Caution should be exercised when rounding them. The jetties are each marked on the outer end by a private light. In June 1981, a depth of about 8 feet was reported available through the entrance. The northern part of the harbor has general depths of 10 to 20 feet. A channel marked by private buoys leads eastward from the entrance to small-craft facilities on the north shore of the harbor. The southern part of the harbor is shoal; the chart is the guide. |
