RedactedNarrative: While myself and Capt. were on vessel patrol in Tybee Creek, a vessel containing Victim pulled along beside of us.  The owner/operator stated Victim had been injured by the propeller.  I did not see any blood in the vessel and Victim was holding a beach towel on her right backside. Victim was conscious and responsive.  I advised them to go to AJ's Restaurant dock while I called Tybee Police Department dispatch in order to have EMS enroute.  Victim received a cut to her upper right buttocks from the propeller after she jumped into the water at the stern of the vessel.  Victim stated she jumped into the water to urinate.  At the time she jumped into the water the boat operator was trying to anchor the vessel with the power pole.  The engine was still running and the propeller was still turning.  The water depth was shallow enough that she could stand in the water without swimming.  Victim stated that when she felt the propeller hit her she jumped back into the vessel and applied direct pressure to the cut.  According to Victim, the cut was approximately 5 inches long and 2-3 inches deep. Victim was checked at the dock of AJ's Restaurant along Tybee Creek by Tybee Island EMS.  She was transported to the hospital where she received 15 stitches.  No alcohol was involved in this incident.
