Atlantis marina is where Boston boaters end up after they've tried the rest.

Protected, secure, slips are available year round accommodating boats up to 100 feet. Water and 30 or 50 Amp electrical shore power is available at at each slip. Private women's and men's restrooms as well as a private shower are available to marina customers.

In addition to the breathtaking Boston skyline and shimmering sunsets, our marina is known as a safe, no hassles facility to keep your boat, depart from to open ocean waters or Boston Harbor, or just spend a leisurely day on the docks with friends.

We have a winter and a summer season. Water and electric is provided year round as well as access to marina restrooms and shower facilities.

Water is provided at each pedestal during the summer and winter. The submerged winter water line is heated and insulated to ensure running water to liveaboards during the coldest winter months.

Off-street parking is provided at no charge to our customers and a guest. The parking lot is well lit, maintained, and plowed in winter.
Dogs and cats are welcome. We love pets and provide a designated dog walking area along the harbor walk and all we ask is that you respect our neighbors and pick up afterwards. There are also some great spots to walk your dog in town such as Belle Isle Marsh, the beach during the winter months, and a short walk down the street at Ingleside Park.
Trash bins are provided at the entrance to each dock and are emptied twice a weak. We pride ourselves on the cleanliness of our marina which is why the bins are never full and frequently cleaned to prevent odor.

boater review

After keeping my boat at multiple marinas in Boston Harbor for 8 years I can finally say I’m home. There’s nothing like sitting back and watching the amazing sunset go down over Boston after a day of boating. The people are friendly and the staff is helpful, responsive, yet manages with a “hands off” style. Great place to keep your boat.
