RedactedNarrative: On July 18th, 2015 at about 14:10 Operator was operating a 21'' Sea Ray. Operator had been towing two of his friends on a tube.  Operator pulled the vessel up near Subject and the other individual so that they could get back on board the vessel.  As Subject was attempting to climb aboard the vessel on the ladder at the stern of the vessel, on the port side, He slipped and cut his leg badly on something on the back of the vessel or on the motor. There was a broken plastic fin on the lower unit of the vessel above the prop, that may be what victim cut his leg on.  Operator said that he had put the vessel into neutral and that the vessel had been sitting still for approximately a minute before Subject attempted to board.  
  
  Approximately 1-2 minutes after the incident occured Officer and I saw the Sea Ray sitting still in Owl Hollow Creek.  The occupants flagged us down and told us that Subject had been cut badly.  I saw that Subject''s leg had a long deep cut on the inside of His left calf. They had wrapped a shirt around his calf as a bandage.  They immediately loaded Subject into our vessel and we told them that we would be headed to Devils Step Boat Ramp and Officer called the Franklin County Dispatch and confirmed that they had an ambulance on the way to the ramp. I held the bandage on Subject''s leg to keep pressure on it until the paramedics arrived. We arrived at the ramp approximately 5 minutes after he was loaded on our vessel and a State Park Ranger showed up shortly after we did.  After a few minutes at the ramp the ambulance showed up and the paramedics bandaged Subjects leg on our vessel. We then loaded Subject onto a stretcher and they took him to the ambulance and then to the hospital in Winchester, Tn.  Origionally we had believed that Subject''s injury had been from being struck by the prop of the vessel.  But after talking to the witnesses and seeing the injury it didn''t appear to have been made by the prop.  It may have been cut on that sharp piece of broken plastic on the motor or something else on the back of the vessel.
