The concrete ramp and floating docks at Monument Beach Marina in Bourne

Launch your boat or kayak from the Monument Beach Boat Ramp and explore the harbors and shores of upper Buzzards Bay.

Store or launch your vessel at Monument Beach Marina to access a wealth of aquatic exploration. Located next to the sandy shore of Monument Beach, this marina boasts 61 slips, 35 moorings, a boat ramp, a dinghy dock, and a fuel station. Public restrooms, as well as private showers and restrooms for marina customers, provide a place to freshen up after a long day out on Buzzards Bay. Moorings and slips can accommodate vessels up to 40 feet; boaters should visit the Town of Bourne website to join the marina wait list. Temporary tie-up space, and transient moorings and slips, are also available. The marina is open from May 1 to October 31.

From the public boat ramp, anyone can launch a boat into the protected waters of Phinneys Harbor — just be sure to watch out for the shoals that dot these waters. From here, you can easily access the head of Buzzards Bay or motor into the Cape Cod Canal. If you’re traveling by paddle, we recommend heading north up the Back River for quieter exploration.

Not yet a boater, but want to learn? Check out Bourne Community Boating, which is based at Monument Beach Marina every summer. This maritime school offers an array of sailing, rowing, and marine science programs for kids and adults to learn boating or improve their skills.

Habitats & Wildlife

Sheltered waters make Phinneys Harbor an ideal place to take in Bourne’s natural beauty. Anchor along the edge of the Mashnee Island dike, which cradles Phinneys Harbor to the northwest, for great swimming, fishing, and beachcombing on miles of sandy, secluded beaches. Look out for piping plovers, marsh hawks, and other shorebirds that make their homes along the beach and in the abundant salt marshes on the causeway’s edge.

In the spring, Phinneys Harbor is also a gateway to the spawning grounds for river herring and alewife, which swim upstream to spawn in Eel Pond and the Bourne Back River.
