RedactedNarrative: Vessel was towing one wake-boarder with 13 passengers on board.  When the skier went down, the operator of the boat reduced speed, causing the boat to plow in the water rather than plane.  The reduction in speed caused two of the passengers seated in the bow of the boat to lose their balance and fall overboard.  (Witnesses stated that the adult passenger was crouched and holding his daughter in the front of the boat.  When the speed change occurred, the adult may have adjusted position, which caused him to lose balance and fall).  The operator turned the vessel off as soon as he realized what had happened, and went to the swim platform to retrieve the individuals.  Both individuals sustained significant lacerations form the propeller.  The adult male sustained one laceration to the posterior thoracic cavity.  The female, age 6, sustained multiple lacerations to both legs.  Lacerations began at the buttocks and continued down the right leg, culminating in compound fractures of tibia/fibula, above and involving the ankle.
