RedactedNarrative: Unit 1 was traveling south on the Waccamaw River when Unit 1 struck an unknown submerged object (Primary Collision) causing Unit 1 to veer right, striking several low hanging trees (Secondary Collision). Unit 1's operator obviously struck the steering wheel with his body and was ejected from the vessel into the water. Unit 1's operator crawled from the water onto dry land and remained for at least 7 hours before being found after a lenghty search. Unit 1's operator was transported to the hospital and sustained injuries as a result of this collision.
