RedactedNarrative: On 06/14/2022 around 1200 I, Officer, responded to a single vessel fire at Fall Creek Boat Ramp on Percy Priest Lake. Once on scene I was able to identify the owner/operator. He had been brought to shore by two witnesses and was uninjured. The vessel remained on fire until it sank just east of the boat ramp. Statements were taken from all parties involved. Subject told advised me that before the incident occurred he had opened his rear hatch to the motor compartment to work on the trim that was not working properly. During this time the vessel began to drift away from the boat ramp due to the wind. Once the boat had drifted so far from the boat ramp Subject stated he wanted to start to boat to bring it back to the boat ramp. When Subject attempted to start the boat he stated he heard the sound of fuel vapors igniting. When he turned around he saw flames coming from the motor compartment. He went to get his fire extinguisher to fire the flames, but he stated to flames began to grow quickly so he jumped off to swim for shore. it was at this time two individuals in a canoe picked him up, and brought him back to the boat ramp. Pictures were taken as well. Rutherford County Fire and EMS assisted on scene.
