RedactedNarrative: The 9'" and JO'" occupants of the vessel are listed as #2 & #3 on page 3 of6 in this report. 
  They are also shown as Below Deck #2 and #3 for their position on the vessel. They were not below deck. 
  The boat was purchased and delivered about a month before the accident. The new boat had two controls for shifting and two controls for 
  throttle which is different from their previous vessels. 
  
  While vessel I was backing into a dock space, another boat was approaching causing the operator to be distracted by its presence. Passenger 6 was standing on the swim platform assisting with docking, with his left leg on the bottom platform and the right leg on the top platform. As vessel I came close to the cement dock the other passengers were yelling at the operator to pull forward. The swim platform started to go 
  under the cement dock. The operator thought he was putting the vessel in forward but grabbed the throttle and gave it more throttle. This 
  caused the boat to go in reverse at a high rate of speed. This caused the cement dock to pinch passenger 6's leg causing his injuries. 
  There was no damage to the vessel.
