Three natural channels lead into Cohasset Harbor through the area of rocks and ledges: Western Channel, which enters between Brush Ledge and Chittenden Rock; The Gangway, a passage which leads between The Grampuses and West Hogshead Rock; and Eastern Channel, which leads between Enos Ledge and West Willies. Although all three channels are marked by buoys, there are numerous unmarked dangers.
The Gangway passage is the widest, but there are unmarked covered 10- and 11-foot rocks in the middle of it, and it should be used only in clear weather and with a smooth sea, even in small craft. Eastern Channel is the clearest and deepest of the three. The best time to enter is on a rising tide.
A prominent lookout tower is near the summit of a hill eastward of The Gladeson the east side of the harbor.
Cohasset Cove, the inner harbor, is protected by a breakwater which extends about 0.1 mile northward from near the westerly end of Bassing Beach. The breakwater is partially covered at high water.
A dredged channel leads southward from the outer harbor to an anchorage basin southward of Bryant Point in Cohasset Cove, the inner harbor. There are three additional dredged anchorage areas: one is immediately southward of the Cohasset Cove anchorage; one in Bailey Creek, in the southeastern part of the inner harbor; and one immediately westward of the southern end of the Cohasset Cove anchorage. In 2005-2006, the controlling depths were 4.4 feet at midchannel, with shoaling to bare in the left outside quarter between Buoy 11 and the breakwater, to Cohasset Cove anchorage, thence 3.7 to 7 feet in the anchorage, except for shoaling along the edge adjacent to Bassing Beach, thence 3.7 feet in the anchorage southward of Cohasset Cove anchorage, thence 4.7 feet in the easterly anchorage in Bailey Creek, except for shoaling near the southwest end of Bassing Beach and in the eastern end of the basin, thence 3.8 feet in the westerly anchorage shoaling to 1.1 feet at the head of the project. The channel into Cohasset Cove is marked by lights and buoys; a light is off Bryant Point.
A rock, which uncovers 6½ feet, is in 42°14’21″N., 70°47’15″W., close to the southerly edge of the channel leading to the anchorage in Bailey Creek. Another rock, covered about 1 foot, is reported in the westerly anchorage, about 65 yards northeastward of the town landing on the southerly side of the anchorage; caution is necessary when maneuvering around the service wharves eastward of this landing.
