RedactedNarrative: Unit 1 was traveling in the Stono River and lost power.  Subjects in Unit 1 called a friend to tow them back.  When Unit 2 arrived the owner/operator of Unit 1 got into Unit 2 and took control of Unit 2.  
  
  After several attempts to secure a line between the two vessels, a passenger in Unit 1 jumped overboard and swam the rope to Unit 2.  The individual was climbing into Unit 2 after securing the line and was struck by the prop of Unit 2.  The subject received a laceration to the left calf and foot.  His foot was also broken and two of his toes had to be amputated.
