Stage Harbor is located at the southern end of Cape Cod and is 25 miles north of Nantucket and 35 miles northeast of Vineyard Haven. The entrance channel to Stage Harbor, has a minimum depth of 9.5 feet, and the channel is reliable, even during stormy weather.
The image above is a view from the southwest looking northeast over the Stage Harbor Inlet, and the deeper portion of the channel is clearly visible. Off to the right (east) is Harding Beach Point, while the southeast tip of Harding Beach itself is on the left (west). The white and black building just inside Harding Beach to the left is the Stage Harbor Light (42 feet above the water, flashing white every six seconds).
Use NOAA Chart 13229.
The initial approach to Stage Harbor is an entry from the southwest via Nantucket Sound. Once you have navigated your way to the area, set a course for red and white Morse (A) buoy SH, which is located at an approximate waypoint of N41 39.168 W69 59.970. If you are arriving from a good distance offshore, Stage Harbor Light (42 feet above water, flashing white every six seconds) is sometimes visible up to 20 miles into Nantucket Sound.
Once you have picked up red and white Morse (A) buoy SH, set a course to the west to intercept flashing green buoy 1 and red nun buoy 2 at the beginning of the channel cut into Stage Harbor. From flashing green buoy 1 and red nun buoy 2, head northeast past red nun 2A, green can 1A, red nun buoy 2B green can buoy 3, and then flashing red buoy 4 (visible in the image above) just off Harding Beach Point.
From flashing red buoy 4, set an approximate course of 60 degrees magnetic for a distance of about .4 mile to intercept red nun buoy 6, and then at an extreme shoal to the north, green can buoy 7. You will want to leave green can buoy 7 decidedly to port on entry. Farther on, green nun buoy 8 will become visible before you turn toward green can 11 and red nun buoy 10. The Stage Harbor anchorage should now be visible in front of you. There are two marinas on the north side of the harbor, but as of this writing, they are not accepting transient guests.
