RedactedNarrative: Witness statements indicate that around 7:45pm two people were fishing from a bass boat in the no wake zone at Shanghai Marina.  They were drifting and/or using the trolling motor.  Operator1 was operating a rented pontoon in the same area.  Operator1 left the pontoon boat in gear at idle speed and stepped away from the boat controls to hang bumpers in preparation for docking.  
  V2 subject noticed the pontoon approaching and yelled at them to stop.  The front of the right pontoon made contact with the left rear of bass boat.  This damaged the bass boat rub rail and fiberglass.  There was little to no damage to the pontoon beyond transfer marks.  Both operators agreed to meet up at the gas dock area of the marina to exchange information and file a report. Field sobriety task were given to operator1 and due to the admission of drinking alcohol, however no impairment was detected and no arrest was made. As the pontoon was docking a passenger fell into the lake and drowned.  The drowning incident is contained in report # 18414981.
