RedactedNarrative: On 6/6/2015 at approximately 14:35 hours I, ICO, was notified by ICO Dispatch of a boat accident involving multiple boats on Morse Reservoir in the area of the marina "Dock D." I arrived on scene just moments after I received the call. Upon my arrival, I observed a white Cobalt motor boat (IN9224BK) floating in between "C dock" and "D dock" and several people gathered around on the dock. I began to inquire as to if everyone was okay and what had happened. Everyone on the dock told me they were fine and did not require medical attention.
   
  Three individuals approached me and told me that they were witnesses to the crash and I provided them with statement forms, which they all agreed to fill out. Witness1 provided a statement that said "saw white Cobalt boat backing out, throttle increased, hit dock, hit Mercury motor on pontoon, turned hard right and launched on top of dock and pontoon boat." Witness2 provided a statement that said "White Cobalt was trying to turn around between 2 docks driver gave the boat too much throttle during the turn and the boat hit a boat on the west side dock and then drove up onto the dock on the east side in between 2 boats causing damage to both boats and the dock." Witness3 provided a statement that said "Walking up the pier toward the marina, saw a white boat accelerate and hit 2 boats that were tied up in there slips, the landed with the nose of the boat on the pier. After telling the driver to turn off the boat, I help get 4 passengers off the boat. Then waited for C.O. to arrive." I collected the statement forms from these individuals and they were free to leave.
   
  I identified the operator and owner of the Cobalt. I asked Operator1 what had happened and he told me that it was his fault and the throttle on his boat had stuck. I asked if he had experienced any problems like this before and he told me no. He told me that he was trying to turn to go forward after backing out of a dock space, his boat had struck a Sylvan pontoon's motor (IN2639DV) to his left and then he made a hard right turn. He said the boat still had too much forward momentum, struck another pontoon boat (IN9688DN) and ended up resting on top of the dock to his right. I also found damage to another pontoon (IN7409DT) adjacent to the dock where the Cobalt landed. I asked Operator1 if he had been consuming any alcoholic beverages throughout the day and he told me that he had drank a beer around noon with lunch. I asked him if he would be willing to complete a few tests so that I could check his sobriety level and he said yes. I read the Pre-Test questions from my department issued form. I performed the Horizontal Gaze Nystagmus Test and Operator1 passed this test by not displaying any clues. I offered him a PBT, which he took, and the result was negative for the presence of alcohol. I explained to Operator1 that he needed to fill out a form called "Report of Indiana Operator's Boat Accident" and he did so.
   
  Operator1 and I reconvened with the rest of his group and I obtained their information. I took photographs of the scene, unoccupied damaged boats, and the damaged dock. Operator1 and his passengers were free to leave. I made contact with marina staff and notified them of the damage to their dock. The staff told me they would make contact with the owners of the unoccupied boats. I provided the staff with information cards on how to obtain a copy of the crash report once it was completed.
