RedactedNarrative: Operator and Passenger travelling a max speed of 25 mph.  Lake was fairly choppy so Operator stayed in straight line, did a slow turn and headed back towards a pontoon boat.  Passenger leaned left and began to fall off of the vessel.  As she was falling the Passenger grabbed Operator around the neck and Passenger’s right leg hit the side of Operator’s head.  Both Passenger and Operator ended up on the water as the jetski stayed upright.
