RedactedNarrative: On September 3, 2018, Subject and friends rented a pontoon boat from Hurricane Marina on Center Hill Lake.  They arrived at approximately 9:00 a.m.  They were on the lake all day and Victim had drank approximately 10 beers.  At approximately 3:30 p.m. operator was driving the vessel back to Hurricane Marina to return the rental.  Victim was riding on the bow of the vessel along with one other person.  They were asked to come back into the vessel safety railing, but refused to do so.  As the vessel approached the mouth of Mine Lick Creek, at approximately 25 mph, Victim stood up about the time the vessel hit some large wakes.  The wakes caused Victim to lose his balance and fall overboard in front of the vessel in between the pontoons.  The operator tried to stop the vessel but was unable to do so before the prop struck Victim.  Victim surfaced behind the vessel and occupants jumped in and loaded him back aboard the vessel.  Occupants called 911 and proceeded to Hurricane Bridge Access area. Myself and other officers met them at the access area with EMS.  Victim was life flighted to Vanderbuilt Medical Center.  He suffered lacerations to his back and deep lacerations to his right arm.
