Blue HIll Harbor is located off the northwest end of Blue Hill Bay just west-northwest of Long Island and due west of Union River Bay. The town of Blue Hill (located on Blue Hill Bay) Has three marine service and marina facilities and one of those three has slips for transient guests. If you plan on using the Blue Hill Town Wharf, keep in mind that the docks are dry at mean low water.
The image above is a view from the southeast looking northwest over the entrance to northwest Blue Hill Harbor. Off to the right (east), Sculpin Point can be seen, while Parker Point is off to the left. In the upper right-hand side of the image, a large mooring field is visible. The town of Blue Hill, and all of the marine service an marina facilities for the area are located here.
Use NOAA Chart 13316.
Blue Hill Harbor is reached via an approach from the south or west via the West or East passages from Blue Hill Bay, respectively.
If you are arriving from the East Passage where it turns into Union River Bay between Newbury Neck and Long Island, first set a course to intercept the area around waypoint N44 23.4298 W68 30.523. Once you have safely navigated to the waypoint, set an approximate course of 308 degrees magnetic for about 2.5 miles to pickup green can buoys 1 and 3, which both mark a rock shoal to their west.
If you are arriving from the south via East Passage, first set a course to arrive in the area of waypoint 44 22.938 W68 31.830. Once you have arrived in the area of the waypoint, set an approximate course of 336 degrees magnetic for 1.7 miles to pickup green can buoys 1 and 3.
After leaving green cans 1 and 3 to port, set a new course toward the harbor opening to intercept green can buoy 5 and red nun buoy 6 (both visible in the image above). It is especially important to leave red nun buoy 6 well to starboard, as a long rock shoal extends out into the harbor from Sculpin Point (visible in them image above center right). Once you are clear of Sculpin Point Shoal, a mooring field with available tie-ups opens up to starboard.
Farther in toward the northwest, you will find green can 7 and red nun buoy 8, which lead around a rock ledge area known as The Triangles. From here you can work in toward Blue Hill Town Wharf or Raines Marine, which offers transient slips. Both are situated in extremely shallow water, however; some areas bare to dry at low tide.
