RedactedNarrative: On the morning of 04/02/2017 Subject went to launch his boat at Rockland Park located in Hendersonville, TN 37075.  Subject stated that he arrived at the boat ramp at approximately 10:30 am.  The boat had recently been repaired and had electrical work done to it.  This service was done in Monroe, Louisiana by Lietzing Marine.  Subject had filled the boat with 21 gallons of premium fuel prior to launching.  After the boat was backed into the water and still on the trailer Subject started the ignition.  
  Shortly after he noticed smoke coming from the passenger side dash.  A new cigarette lighter had been installed there and this was where he noticed the source of the smoke first.  He then turned around and noticed smoke at the stern of the boat.  He opened the cowlan and saw flames spread out along the bottom of the compartment.  He got off the boat and unhooked it from the trailer setting it adrift for fear of an explosion.  He drove his truck with trailer attached to the top of the ramp to extend the distance of the truck from the burning boat.  The boat continued to burn to the waterline until Hendersonville Fire Department arrived to further extinguish the flames.
