RedactedNarrative: Officer and I docked the patrol boat at the refueling dock at Barkley Marina to refuel. One of the deck hands notified me about two rental jet skis were involved in an accident with a shoulder injury to one of the operators. 
  
  I spoke to subject1 who observed the accident from a pontoon boat that was anchored near the beach area. Subject1 stated that everyone was getting ready to head back towards the marina to turn in the pontoon boat and jet skis. Operator2 was setting on a Jet Ski next to the pontoon, while Operator1 was on the other Jet Ski. Operator1 was attempting to pull next to Operator2’s Jet Ski, when he approached at a fast rate of speed hitting Operator2’s Jet Ski and knocking him off into the water. 
  
  Upon collecting all the information from all the parties involved, Officer and I left the refueling dock and placed our patrol boat into the slip located on dock 1. I proceeded to Trigg County Hospital where Operator2 was transported by personnel vehicle. I located the father of Operator2 and Operator1. I asked Operator2’s father if he observed the accident. Operator2’s father stated that he was talking with Operator1’s father on the pontoon boat, when out of the corner of his eye. He observed Operator1 hitting Operator2's Jet Ski and knocking him off. Operator2 started yelling, I need some help. I helped Operator2 onto the boat and he was complaining of his left arm hurting.
  
  I spoke with Operator1 and he stated that he attempted to pull next to Operator2's Jet Ski, when he hit a wave causing the Jet Ski to shut off, still traveling around 25 to 30 MPH. The front of the Jet Ski struck Operator2's Jet Ski at a 45 degree angle knocking him off. Operator2 returned from X-Ray and he advised that he was sitting on the Jet Ski, next to the pontoon boat, when operator1 came towards me really fast and collided. The front of his Jet Ski struck his Left side knocking him into the water, causing a fracture to his left arm. 
  
   I observed the damage of both Jet Skis and Jet Ski #1 (Operator1) proceeded at a high rate of speed, struck Jet Ski #2 (Operator2) with the front. Causing serve damaged to the top and front of Jet Ski #2, and then striking Operator2 left side from the elbow to the top of his shoulder. Operator2 was knocked into the water from the impact.
