The moorings and berths at the town marina are under the control of the harbormaster, whose office is on the west side at the town landing. A speed limit of 4 miles per hour is enforced in the harbor.
Members of the Dennis Yacht Club moor their boats in the small bight on the west side of the channel just inside the west jetty. A marina, on the west side of the harbor about 0.35 miles southward of the jetty light, has depths of 6 feet reported alongside its service floats. The marina has a 20-ton mobile hoist for dry covered or open winter storage. Gasoline, diesel fuel, water, ice, pumpout facility, provisions, marine supplies, guest berths, and charter fishing boats are available.
About 250 yards southward of the marina is the town landing with ramps, two piers, and float landings at which berthing with electricity and water are available.
A public small-craft launching ramp and an adjoining float landing are on the east side of the harbor, about 0.4 mile southward of the jetty light.

Sesuit Harbor has two jetties. The west jetty is marked by a light, and the east jetty by a daybeacon. A lighted bell buoy, about 1 mile north-northwestward of the entrance, marks the approach. In 2009, the midchannel controlling depth was 5.4 feet. The channel between the jetties and the harbor are subject to frequent shoaling, and local knowledge should be obtained before entering.
