RedactedNarrative: On sunday, may 17, 2015, operator and family members had launched their 21 foot skiff at taylors creek access area.   The family then proceeded to the eastern portion of shackleford banks where they spent the day on the beach.  The family departed the beach at approximately 16:30 hrs.  Operator was operating the boat at approximately 20 mph while running parallel to shackleford banks, approximately 200 yards off the shore line.  Once the boat was approximately 1.75 miles from beaufort inlet and at approximately 17:00 hrs, a large wave caught the boat and flipped it left to right.  Operator later advised that he thought the boat had taken on water causing the weight distribution to be off centered.  The boat floated upside down as it made its way to the shore.  Operator and family members swam to shore and was picked up by the park service.  Tow boat us recovered the vessel and transported it back to taylors creek access area.  Ems was dispatched but subject declined medical attention for minor cuts on her head.
