Although more open than Eagle Harbour a mile to the north, Blakely Harbour is far quieter with no ferry traffic, no marinas, and only a small handful of private moorings around the edges. Depths are suitable for anchoring throughout the inner half of the harbour with plenty of swinging room and good holding in thick mud.
Although open to the east shelter is perfectly adequate in settled weather. The foreshore is private land so dinghy landing is restricted but the views across the bay to the Seattle skyline would be the main reason for anchoring here.
