Potts Harbor

You’ve just been awakened from a night of slumber by a knocking on your hull. You come up from below to be greeted by a smiling dock attendant delivering a fresh blueberry muffin and hot coffee. You are either dreaming, or you have spent the night at The Dolphin Marina and Restaurant, a family-owned operation in business for over 50 years. Located at the end of Harpswell Neck about halfway between Portland and Small Point, The Dolphin is a favorite with Casco Bay locals and those cruising to or from Down East Maine.

Approach & Cautions

If approaching from the west, keep bell buoy “6”, Little Birch Island and Horse Island to port. The marina lies ahead once you pass Horse Island. If approaching from the east, turn to starboard once clear of Lighted Gong “8” at the end of Bailey Island and head for Nun “2” at the northern end of Haskell Island. From there, a windy but well-marked passage between Haskell and Potts Point brings you into the harbor.

Docking, Anchorages, or Moorings

The Dolphin has dockage and moorings and anchoring is mud bottom in 20-30 feet of water around the fringes of the mooring field. The harbor is well protected from ocean swell and against the prevailing southerlies but can be unsettled in easterly breezes. The approach to the docks is deepwater, with 12’ on the face dock at mean low.

Up the road 4.5 miles at 1220 Harpswell Neck Rd is Uncle Pete’s Community Market, a small grocery with take-out items.

Brunswick lies 12 miles away and is accessible via the Dolphin’s courtesy vehicle. You can meet virtually any provisioning need in the town center or in the Cook’s Corner area – Hannaford and Shaw’s supermarkets, three farmers markets (info here), a Walmart and several hardware stores.

Dine Out

In addition to the Dolphin, Erica’s Seafood lies right next to the Dolphin and there are numerous dining options if you can secure transportation to Bath or Brunswick.

In addition to hiking the shoreline at Basin Point there are several hikes within a short car or bike ride. The Harpswell Heritage Land Trust publishes an online summary of hikes in Harpswell.


Other places to explore a short distance from Basin Point include Eagle Island (summer residence of Arctic explorer Adm. Robert E Peary) and Whaleboat Island. Eagle Island will be closed this summer due to the damage incurred in the 2024 winter storms that destroyed the pier and eroded the shoreline in front of the house as well as the east seawall and bastion, but you can see it in the great video on their web page.

Whaleboat is a Maine Coast Heritage Trust preserve.
