The Back Channel is a very calm location to stop. Jason the manager could not have been nicer. He sent us a mooring field map in advance so we knew exactly where to go. Grabbing a mooring there is a little challenging with the current and the pots but absolutely doable. Dinghy ride to Chauncy Creek Lobster Pound is a plus.
Beautiful harbor, a short walk (or bike ride) to restaurants and the market. Staff was helpful and friendly. Launch drivers could try and throw less of a wake.
Easy in to Edgartown. One quick call to the Harbormaster who told us which number yellow mooring we would be staying on. The harbor is set up well with the town moorings in yellow and clearly numbered 1 to 100 (or so). Also, loved the water barge where you can fill the tanks 24/7.
