RedactedNarrative: On 08-15-2014 Officer was called in response to a boat that had caught on fire near Boat Ramp 2, Clinton State Park, Clinton Lake, Douglas County, KS. Upon officer''s arrival at approximately 1835 HRS officer observed a 28 Ft, Beneteau Sail Boat, KS Registration; smoking after the fire was put out by Wakarusa, and Clinton Township Fire. The boat appeared to be a complete loss. 
  
  Officer spoke with the operator at the time of the fire. Operator advised he and his son were the only people on the boat at the time of the fire. Operator advised officer the boat had a diesel engine and prior to going on the water his son, had filled the tank with gasoline. After receiving knowledge of the gasoline, Operator advised he and his son attempted to remove the gas from the tank and refuel with diesel fuel. 
  
  Thinking most of the gas had been removed from the fuel tank they decided to burn what gas might still be in the tank. They made it as far as the no-wake buoy line. At which time the engine compartment began to smoke and the engine quit. 
  
  At this time subject observed the vessel having problems and responded to the area. Subject used a tow rope and towed the sailboat to the docks at boat ramp 2. Once to the docks, Subject gave them his fire extinguisher. They used the fire extinguisher with little to no result in the fire. 
  
  The fire eventually caused the ropes to melt allowing the boat to break away from the dock. Seeing that the boat was moving towards Marina Dock A, Subject and the operator once again tied to the boat and towed it to the boat ramp dock. During this second tow the mast of the sailboat fell over and made contact with Subject''s boat. The heat from the mast caused minor melting to the back seat, and minor damage to the hood cover on Subject''s boat. 
  
  Fire Lt. took an initial report for the response. After conducting his investigation into the cause of the fire, he did not feel it was a case of arson. His report is attached.
