RedactedNarrative: Vessel 1 was being driven by operator 1.  Vessel 1 was in the process of towing a water skier at an estimated speed of 10-20 mph and accelerating to help get the skier to plane on the surface.  
  
  The skier eventually planned for approximately 30 seconds before falling.  This fall was solely the result of inexperience, and the skier was wearing a USCG approved PFD at the time of the accident.  The fall resulted in a fractured leg that required surgical treatment.
