RedactedNarrative: On July 4, 2016 at approximately 1430 hours Sgt. and I responded to a boating incident located in Hall County on Lake Sidney Lanier at the Aquland Marina gas docks.  At approximately 1435 hours I arrived and observed a young white male with a laceration to the left arm.  He advised me that he attempted to jump from the port bow portion of vessel 1 onto the dock and missed thus hitting the cleat on the dock causing the laceration.  All parties refused to provide witness statements.  ***END OF REPORT***
