Unit 1 was pulling a tube carrying 2 passengers.  One passenger fell off of the tube.  The other occupant remained on the tube.  While attempting to retrieve the person in the water, the operator turned the vessel allowing the tube to swing to the bow of the boat.  

The operator lost sight of the tube and the person on the tube.  As the boat continued to move forward, the vessel struck the tube with the bow and the tube slid to the stern on the starboard side where the victim went under the boat and was struck by the propeller.  Victims injuries include: prop cuts to the rectum, female perineum, and type 1 or 2 open fracture of lateral malleolus of left fibula.
