RedactedNarrative: Was dispatched to a fight in progress and boating accident call at KY Dam Marina Fuel Dock. Upon arrival, KSP Troopers had taken several people into custody. Only 1 person remained with knowledge of any boating accident. 
  
  Myself and Officer interviewed subject who had rented the 2 PWC involved in the accident as well as a houseboat from KDM. 
  
  Subject verbally stated and gave a written statement that he was operating #6 PWC with his son Operator2 as a rear passenger and that Operator1 was operating #5 PWC with his girlfriend as a rear passenger.  
  
  Subject stated that the #5 PWC came in front of his and stopped abruptly causing his #6 PWC to strike the #5 in its left or port side just rear of the handlebars. Subject stated this is how his son Operator2 cut his left ankle badly and had to go to the hospital. 
  
  Subject stated the #5 PWC had been having mechanical issues and he thinks the PWC died in front of him before impact. The #5 PWC had fiberglass damage at the midline of the hull near the area where an operators left foot would be while in the operating position. A lot of blood was seen on the #5 PWC. The handle bars on the #5 PWC were broken as well, indicating someone went over them or into to them at impact. 
  
  Subject's story does not coincide with the physical evidence and injury of his son. There was minor scratches to the front of #6 PWC. Officer and myself next interviewed Operator1 at the Marshal County Jail. Operator1 stated he was operating #6 PWC with his girlfriend as a rear passenger and struck #5 PWC when it stopped in front of him. 
  
  Operator1 stated that Operator2 was operating #5 PWC with no passengers. Operator1 stated he had been drinking alcohol that day and was arrested shortly after collision by KSP for A.I., Disorderly Conduct, and Resisting Arrest. That same evening Officer and myself interviewed girlfriend at her residence. She gave a statement and in writing that she was riding on the rear of the #6 while her boyfriend Operator1 operated it. She stated that Operator2 was operating the #5 and they were operating close to each other and splashing water on each other when they got too close and the #6 PWC struck the #5 PWC in the left/port side causing Operator2 to be ejected. 
  
  She stated she drove the #5 PWC and operator2 drove #6 back the marina and it was running fine. On 6-4-2016, Officer and myself interviewed and got injury pictures from Operator2. Operator2 stated and wrote a statement that he was operating #5 and Operator1 was operating #6 when his stalled and the #5 ran into him causing him injury.
  
  Operator2 also stated that his father had lied to protect him when questioned about his fathers statement. It is my conclusion that alcohol played a contributing factor based upon the arrest report at the marina and from statements made during interviews that they had been consuming alcohol. 2nd contributing factor is reckless/careless behavior for operating too close to another PWC. 3rd contributing factor is operator inattention for each operator not being aware of the other PWC being so close and not being aware of the distance needed to maintain safe stopping.
