Winter Harbor is located on the upper Maine Coast just north of the Schoodic Peninsula. Geographically speaking, Winter Harbor is five miles east of Mount Desert Island and 24 miles west of Great Wass Island.
The image above is a view from the south looking north over Winter Harbor where it empties into the Atlantic Ocean/Frenchmans Bay. Off to the right (east) is the Schoodic Peninsula, while in the far center left portion of the image are small Mark and Ned islands. Farther up in the top center part of the image, the town of Winter Harbor can be seen as white specks dotting the otherwise lush green landscape. Grindstone Neck is the large forested piece of land to the left (west) just north of Ned and Mark islands.
Inside Winter Harbor there are four marinas and marine facilities, but only one of them accepts transient guests (moorings only). If you need to fuel up with either gas or diesel fuel, the Winter Harbor Co-op was pumping both at the time of this writing. There are two other facilities in town, and among all four, you may be able to finagle your way into a place to tie up. Dont come to Winter Harbor expecting a dockside tie-up, however.
Use NOAA Chart 13318.
Winter Harbor is typically approached from the south via a passage through the Atlantic opening of Frenchman Bay west of the Schoodic Peninsula. Alternatively, there is a northern passage off Frenchman Bay between a series of small islands just northwest of the main Winter Harbor opening. This passage is sparsely marked, but is generally deep, save for a narrow point at green daybeacon 3 northeast of Spectacle Island.
Approaching from offshore, first set a course for flashing red (2+1), red and green (RACON) buoy FB, which is located at an approximate waypoint of N44 19.352 W068 07.400. Once you have safely navigated to flashing red (2+1), red and green (RACON) buoy FB, set a course of about 055 magnetic for approximately 3.1 miles to intercept flashing green, red and green buoy MI, which is visible in the image above just southeast of Mark Island.
After you have cleared flashing green, red and green buoy MI by about .1 mile, set a new course of approximately 022 degrees magnetic for about one mile. This should put you between red nun buoy 2 and green can buoy 3. From here, you can head north into Henry Cove, making sure to to mind red nun buoy 4 marking the shoal at Guptill Point. Winter Harbor Marine is located here (moorings, repairs).
Alternatively, from red nun buoy 2 and green can 3, you can head northwest toward red nun buoy 4 and red daybeacon to reach Inner Winter Harbor. The Winter Harbor Co-op is located here. If you are looking for a place to drop the hook, Sand Cove is located just below and northwest of red nun buoy 2 and green can buoy 3 at Harbor Point.
