I just got back my trip to Coffin Bay a couple of weeks ago. It's a lot of sailing, but if you don't mind a night sail or two you can do the round-trip in a week. Our
route to/from North Haven was:
Night sail (via South Neptune Island)
Avoid Bay (anchorage)
Boarding House Bay (stop)
Gallipoli Beach (anchorage)
Black Springs Cove (stop)
Coffin Bay township (anchorage)
Williams Island (anchorage)
Memory Cove (stop)
Wedge Island (anchorage)
Edithburgh (anchorage)
The sailing and
anchorages were spectacular
.
506 nautical miles all up!
