Good advice above. I'd strongly recommend a side trip to Edenton and/or Manteo while you are at it. On the C&A canal leg, we really like stopping at Atlantic Yacht Basin, an easy walk into the adjacent village and nice folks. Good fuel prices too. There is a free dock across the canal from them that we have used as well, and the walk is only slightly longer across the bridge.
