Have an opportunity to take friend's 36' sailboat - draft 6 1/2, fin keel, to Rockland, Maine from Cape Cod. Only have 7 days. Prefer to do day trips. What ports would be recommended? (Concerned about lobster pots). Can make Cape Ann the first day. Can we make it through with the currents/depth or go around? Have sailed our own boat from Cape Cod to Bahamas many times but never to Maine.
