Carefully! It wasn't too bad. In areas were there was a decent tidal range, we just went under bridges at low tide. When there wasn't much of a tidal range, ie Morehead City, we went outside. We did have a bit of a problem around Roanoake where, if the tide was low enough to get under the bridge, then the charts said there wasn't enough water to float. Fortunately it had been recently dredged and we made it.

We did have a real problem in the Dismal Swamp Canal and lost our vhf antenna and wind instruments to a bridge. I'm pretty certain that we caught something hanging below the bridge as there was no reason for that bridge to be lower than the one twenty yards earlier that we passed under without a problem.
