Not to sure about the camping part of the equation, but I've launched my tandem island from several places near Nags Head, NC.
Many local cat sailors launch from this site on the sound:

Further south on the OBX can get 4x4 beach driving permit and drive out and launch most places on the ocean side. Have been down to the Hatteras point with friends that have way more capable offload vehicles than me but never had the chance to take my Hobie TI.
