in New England
all seem to be quite expensive. If you book a slip for the season it is a little more reasonable but still not cheap
. I bought my boat in NY and kept it in RI for the summer. I found a mooring in Bristol for $1500 for the season. Down side, it was almost two miles from my mooring to the main harbor and the dinghy
beach. Biggest problem was the high tides required dragging the dinghy
wayyyyy up the beach or dragging it wayyyyy back down the beach at low tide. Parking in Bristol was restricted by the waterfront so had to park two blocks away.
If you do a little searching I think you could find a mooring on the west side of Narragansett Bay for the same or less and probably a better situation for the dinghy.
Also spent about a month anchored in the CT River across from Essex. No one seemed to care and a friend who lives in the area knew of no regulations
or restrictions. But again the biggest problem there was finding a spot for the dinghy. Like Bristol I had to drag it up a beach, mud in this case.
Have you checked Activecaptain.com for researching marinas? It has a pretty complete and informative database covering the whole east coast
