on 6/27/10 at approximately 1900 hours unit 1 travelled into rough shallow water near the Murrells Inlet north jetty on the inside beach to attempt to pull a boat off the beach. Before making it to the shore the vessel unit 1 lost power and was flooded by the waves coming over the port side of unit 1. Unit 1 turned on its side and rested on the bottom. The captain and the passenger walked to shore.
