Burt, By my standards the New England marinas
are on the expensive side, but when I consider the geographic range that you've identified, I would look at Onset, Massachusetts
Just on the south side of the Cape Cod
Canal, you'll find Onset has a couple of marinas
and a very good protected anchorage. The small town has convenient, grocery, pharmacy, post office, library, & restaurants a short walk from the town dinghy dock
can be swift at the well-marked entry channel and there's usually a need to do some "crabbing" and watch your leeway, but once inside it is very peaceful.
