RedactedNarrative: Operator stated in a witness statement that he rented a PWC (V1) from Zephyr Cove Marina at approximately 1600 hours. Operator was riding as a passenger for the first half of the ride with the operator being Passenger. At approximately 1630 hours Operator switched places with Passenger and began to operate V1 with Passenger as passenger. Operator stated he was going approximately 40 MPH heading north near Round Hill. At approximately 1634 hours V1 began to fish tail and hit a wave ejecting both individuals into the water. Passenger stated he believed his knee contacted the back of Operator's head bearing him unconscious. When Passenger swam to the surface, he saw Operator unconscious in the water face down in his life jacket. Passenger swam to Operator and turned him over and began to flag down another vessel for help. The good Samaritan aboard the vessel was able to pull Operator and Passenger to safety and contacted 911. Operator was still unconscious at this time and had sustained a laceration to the back of the head. According to Tahoe Douglas Fire Department (TDFD) call detail the 911 call was received at 1641 hours.
  
       Once on board, Operator and Passenger were transported to Round Hill dock where they were contacted by TDFD medical personal at 1651 hours. TDFD medical personal began to perform first aid to Operator who at this point had regained consciousness. After first aid was administered Operator was placed on a stretcher with a C-Collar around his neck and transported to Kahle parking lot where he was care flighted to Renown Regional Medical Center for treatment at approximately 1720 hours. When Operator arrived to Renown he was treated by a doctor and received 3 staples to the back of his head for the laceration. No further medical treatment was given, and he was able to clear from Renown under the care of his parents. 
  
  I attempted to contact Zephyr Cove Marina to retrieve the rental agreement and identify the PWC that was being operated. Due to the Forest Service closure put in place due to surrounding fires there was no personal at the marina to get a copy of the rental agreement. The vessel being operated at the time of the incident is unknown as of 08/30/2021.
