60 feet is OK but 7 foot draft will be a bit tight in some spots in GA, SC and NC.
I did Annapolis
to Charleston, SC last October with 4 - 9. We went soft aground twice. With 6 ft draft it would be an adventure and with 7 ft it would not. Once you hit Beaufort
, NC the tide will define everything. The tides south are high and of course low. Prediction is not as easy as it might seem between all the inlets.
Jumping in and out at the class A inlets would be the better course. Getting far enough south would afford that option. This clearly is a time when being in a hurry would be unwise. You need to pick your better options on purpose. You need to hold fast if the time is not right. Enthusiasm is a poor substitute for prudence.
