According to the owner of the PWC that the injured was riding the operator/injured suddenly accelerated and without warning lost control of the PWC and crashed.  He saw him fly through the air and it appeared the PWC had struck him as it rolled across the surface of the water.  The owner and a few other riders found the injured in the water.  A boater passing by took the injured onto his boat and brought him to shore with medical attention.  The operator had been drinking but how much was not known.  PFD was worn and had the safety lanyard attached but the pull-pin kill switch was not on the lanyard or being used.  Alcohol, operator inexperience, wake-jumping and speed all were causes of this accident.
