May be the next cove up from Rogues Harbor......
Used to launch my big scow from there 20-25 years ago. Very nice place.Kent County, MD has some fairly decent launch areas, but you need a county permit (cheap). Go to the Kent County website for info, etc. Manny ... If no one has mentioned it get a copy of the "Chesapeake Bay Cruiser Guide" (published by Chesapeake Bay Magazine) or Shellenbergers "Gunkholers Guide to the Chesapeake". Both in combination are invaluable if you want to travel throughout the Ches. They list all the popular anchorages, list the 'sights to see', show where supplies, fuel, etc. are available, list the 'quirks' in the anchorages and entrance creeks (that the NOAA charts seem to ignore,)etc. etc. etc. (My wife and I help edit one of those).
