Called ahead to make sure there was a mooring that would be appropriate for our tonnage (270,000 lbs). They had a mooring with 1000 pounds of weight on the bottom. We moored but kept an eye on the anchor watch periodically throughout the night - we didn't move other than an arc around the mooring. Weather was calm. The reason I belabor this point is this was a first for us and we wanted to err on the side of caution. People in the harbor were very helpful and friendly. Picturesque town. Enjoyed watching the ferry from Connecticut. I would go back again because it was nice and peaceful. We were there midweek end of July.
