Try Hinckley Yacht Charters:

While you aren't quite far enough to the NE, you will be on the doorstep to
god's country. I have been throughout the Caribbean, almost all of the
Bahamas, and the entire east coast of the US from Key West to New England.
These are the finest cruising grounds on this side of the Atlantic, BAR NONE!

PS: I have no affiliation with HYC, nor have I ever chartered with them, but I
have cruised this coast many times, and plan to be back again soon. There are
also other charter outfits in the area.
