RedactedNarrative: On July 6, 2017 Operator, passenger & victim were headed out on Clear Lake with the intent of tubing. Passenger was in the middle & Occupant2 was in the rear of the PWC holding the tube and rope.  All 3 individuals were facing forward as V1 travelled in a southerly direction from the dock/residence.  
  
  As V1 reached the 300 foot buoy line, victim Occupant2 released the tube (Airhead Matrix V2) and began feeding out rope.  V1 was traveling at or near idle speed as the rope was nearing its full length.  The PWC struck either a large wave or a boat wake which caused the victim Occupant2 to fall off the rear of the machine, into the water.  When this happened the tow rope became tangled around the forearm of Occupant2's left arm.  
  
  Passenger informed Operator that Occupant2 had fallen off.  At this time Operator, not knowing the rope was around Occupant2's arm, throttled forward in a circular pattern in an effort to come back and pick up the victim. As the machine powered forward it appears the rope tightened around the forearm of the victims left arm and cut through the tissue DE gloving the arm to the wrist joint where the hand was then amputated by the force of the rope pulling. The victim also had a rope burn across his left armpit and shoulder. Upon return of V1, the injuries of the victim were discovered and the victim was assisted up onto the PWC and driven back to the dock where 1st aide was given & 911 was called.  All 3 individuals were wearing life jackets.
