Coffin Island, thickly wooded, is joined to the mainland NNW by a shoal bank with depths of less than 4.6m. Another bank, with depths of less than 5.5m, extends about 0.3 mile S of the island. At the N end of the island, there is a small boat harbor, dredged to 1.8m, with several small wharves. Coffin Island Light is shown from a white octagonal tower, 16m high, situated on the S end of the island. A lighted bell buoy is moored midway between Coffin Island Light and Moose Head, the W entrance point of Liverpool Bay.Black Point (Mersey Point) (44°02'N., 64°41'W.), about 0.8 mile NW of Moose Point, is a projection on the S side of Liverpool Bay. Rocks, above and below water, extend about 137m NE of the point. A patch, with a depth of 6.4m, lies about 230m NE of the point.
