Transient Month slip Rhode Island area

[davil]

Need some ideas as to where leave my boat (30 Cape Dory) for about 3 weeks? while I go back home.
Will be in the area of Montauk, can sail up or down the coast within reason.
Like to avoid the daily transient rates and the marina does not have to have any amenities.
could be Rhode Island , Connecticut ?
Otherwise was thinking maybe just hauled out and live the boat on the hard.
Any ideas or references appreciated.
