The main entrance to Gilkey Harbor is from southwestward between Job Island and Ensign Islands; the controlling depth is about 27 feet in midchannel between Minot Island and Seven Hundred Acre Island. Unmarked rocks of less depth are near the sides. The channel is partially buoyed and easily entered. The entrance from the northward is marked by Grindel Point Light (44°16’53″N., 68°56’35″W.), 39 feet above the water, shown from a white square tower with a green square daymark, close to an abandoned lighthouse on the north side of the entrance. The State ferry slip, and a municipal float landing with 12 feet reported alongside, are close southeastward of the light; a municipal small-craft launching ramp is adjacent eastward of the shore end of the ferry auto ramp. A lighted bell buoy is west of the entrance, and the channel into Gilkey Harbor is partially marked by buoys.
Small craft can also enter Gilkey Harbor through narrow, crooked Bracketts Channel, westward of the south end of Islesboro Island and eastward of Job Island and Minot Island. The unmarked channel is said to have a controlling depth of about 6 feet. The best water favors the east side.
No difficulty should be experienced in entering Gilkey Harbor from the southward or northwestward with close attention to the chart and bearing in mind a number of unmarked 14- to 18-foot spots in the northern half of the harbor. Wooded Thrumcap (Thrumcap Island), near the middle of the harbor, has a reef extending westward from it which is marked by a buoy. Lobster Rock, awash 0.6 mile east-southeast of Grindle Point, is unmarked.
