About to close on a well kept eighties 36' Marine Trader Sedan. I'm moving out of a 27' Island Packet sail, and this will be a big change. I plan to bring her south from New England to SWFL next early fall. I have plenty of big ship blue water experience, but have never traveled the ICW and am interested in anyone's opinion as to best navigational plan and literature. Slow & steady 6 kts. Particularly, best advice getting from the Cape Cod canal to Norfolk?? Thanks.
