Operator was in the process of trailering the pontoon at the boat ramp located at Cherokee Dam.  At the time of the incident Operator had one passenger on board. fiancé and owner of the vessel, was standing port side and outside the railing observing the alignment of the pontoons with the trailer bunks. 
  
  Owner’s son, had backed the trailer into the water. The trailer was not at a sufficient depth to allow full extension of pontoon/bunk contact. The subsequent striking and abrupt stop of the pontoons to the trailer bunks caused owner to be ejected from the vessel and resulted in her striking her head and right knee on the vessel trailer. EMS transported her to Jefferson Memorial Hospital for treatment. 
  
  All involved parties and vessel were at Jefferson Memorial Hospital on officer arrival.
  
  Based upon officer investigation, the operator was at fault for not requiring his passenger to be behind the railing and seated during the trailering of the 24'' Sylvan Pontoon.
