Just to give an idea of how the conditions can change in nc. Last week i went out with the Instagator out of Swansboro, and the sea was glass, but because of storms passing close by the visibility was 0 on three different wrecks. I tried again yesterday, and the seas were 3 to 5 feet and choppy, but we managed to get 2 dives in off shore. Also i cannot recommend Instagator enough. Captain cindy dives all year around, she could probably accommodate for an additional passenger, and she runs a 6 pack boat instead of a cattle boat like other operations.
