RedactedNarrative: On Tuesday, June 20th 2017, at roughly 14:43 hours, KSP Post 4 dispatch notified me of a boat accident on Rough River Lake. Dispatch advised of no injuries, and a pontoon had hit a private dock causing damage to the dock, their pontoon, and a pontoon that was docked in a slip. I contacted the caller who reported the accident and asked him a location of the accident. Subject stated that two other property owners had come down to check on him and his wife, and they have already contacted the dock / pontoon owner to inform him of what happened.
  
  I arrived at 15:46; Subject1 and subject2 were sitting on their pontoon waiting. I began to gather identification of both parties and the tag information for both vessels. Subject1 began to explain the accident, while I was gathering information and taking video of the accident site. They were traveling west on Rough River lake trying to run the old gas out of the tank. Subject2 stated she could smell gas coming from the stern of the vessel. While Subject2 was up looking for the possible gas leak, Subject1 (who was operating the vessel) turned around to also look for the possible gas leak. Just when Subject1 turned back around to face the bow, he saw the dock and knew it was too late to steer away. 
  
  I asked Subject1 how fast he thought he was traveling, and he stated that he was between 4,000 - 4,300 RPMs. I asked him if he thought it was roughly between 35-40MPH and Subject1 said it sounded pretty close to how fast he was going. I took body cam footage of both pontoons and their damage, along with the damage to the dock.
  
  I told them about the boat accident report, and told them that if their insurance company needed the report to contact our Headquarters. I provided Subject1 with my cell number, Headquarters number, and the CAD number for a reference. I wrote the same information down on a piece of paper and left it on the front door of owner’s home.
  
  Subject1's pontoon had damage to the front starboard side toon, just below the navigation light. The dock had damage to the side facing the main lake, where the pontoon made contact, and about 3 or 4 boards had been broken due to the impact (one of which had the cleat that was holding other boat owner’s pontoon on the port side). The finger of the dock, that was hit, was canted due to the impact at the joint, where the main dock and the finger meet, and the metal joints in between had a slight bend. The unoccupied pontoon had an indention in the rear starboard side toon, parallel with the motor mount, where the impact moved the finger of the dock and hit his vessel.
