Here is one idea
I live around 35 miles south of Wilmington. I could not find my Wilmington phone book for more options, but I did find one possible source if you are looking to rent a small boat. Google "Salt Marsh Kayak Company" They rent some small sailboats out of Wrightsville Beach. If I can be of any further help let me know. My cell phone is 910-795-6757.Jack Jackson
