Eastern Harbor sits in between Moose Neck and Cape Spit on the shores of South Addison, Maine. Eastern Harbor is 25 miles northeast of Mount Desert Island and 25 miles south of the United States/Canadian Border. The harbor is mainly used by commercial lobstermen, but is also a favored stopover for cruisers transiting the North Maine Coast.

Use NOAA Chart 13324.

Approach from the south. Pick up the red and white Morse (A) buoy west of Big Nash and Nash islands, and then proceed on a northeast course staying east of Pot Rock and the Ladle.

The inlet itself is marked by a green can buoy and a red nun buoy off of Eastern Pitch and Marsh Island, respectively. Two more nun buoys mark the main channel until Otter Cove, where the channel continues to the north-northeast with depths diminishing to seven and eight feet toward the head of the harbor. Otter Cove is a popular mooring area for lobstermen to tie up their boats.
