Duke, The ICW goes all the way to Brownville Tx
What part are you contemplating? Unless you are shallow draft, New Jersey is an outside passage. There has been more that enough said about the Chesapeake bay but it can be glassy flat or very boisterous. The canals through the Virginia swamps are draft sensitive, the sounds of North Carolina are well documented, after that it is mostly canals. I have some friends that have made the trip a few times and I wonder how you could put a 6 weeks trip onto a DVD that didn't either scare the hell out of you or make you complacent.
