Clearwater to Newport
I am planning a cruise from Clearwater Fl to Newport RI over a 2 week period (end of May thru early June). I plan to pass through the Keys at Marathon, stop in Charleston, SC then on to RI. I intend to stay outside and not use the ICW. Any advice would be greatly appreciated specifically relating to the Gulf Stream, Marathon key (I draw 5.5''), weather, Charleston harbor (access, marinas, anchorages) and Cape Hatteras (wisdom of going offshore vs the ditch)?
