At Searsport, west of the entrance to Mill Brook, there is a town landing with 4 feet reported alongside the float and pier. A small-craft launching ramp is adjacent to the landing.
Long Cove is eastward of Searsport Harbor between the northwestern shore of Sears Island and Mack Point. The upper half of the cove is shoal, but good anchorage can be selected in the middle just inside the entrance in depths of 10 to 24 feet, sheltered from all but southwesterly winds.
Navigation:
As the pier at Mack Point is a major destination for cargo vessels transiting Penobscot Bay, caution must be taken to steer clear of these vessels. Natural depths in the main channel of Penobscot Bay provide depths of over 40 feet to within 1 mile of the facilities at Mack Point, thence depths of about 35 feet to a dredged access channel which leads to a turning basin off the facilities. In 2005, the controlling depth was 34 feet in the access channel and in the turning basin except for shoaling to 33.8 feet in the northeast corner and 31 feet in the northwest corner.
Ledges make off 0.3 mile from the western shore of the southern half of Sears Island; one of these ledges, Sears Island Ledge, is bare at low water. A bell buoy is about 0.5 mile southwest of Sears Island and at the south end of the ledge. Two other buoys mark the limit of the ledge westward of the island.
