RedactedNarrative: ON 02/20/2016  AT APPROXIMATELY 1633 HOURS, VESSEL 1 WAS DOCKED AT THE SITE SIX LAUNCH RAMP DOCKS. THE OPERATOR OF VESSEL 1 THEN PUSHED THE VESSEL OFF OF THE DOCKS BEFORE ATTEMPTING TO START THE ENGINE, PREPARING TO LEAVE THE AREA. PRIOR TO STARTING THE ENGINE THE OPERATOR COULD SMELL THE ODOR OF GASOLINE HOWEVER HE DID NOT SEE ANY FUEL LEAKING WITHIN THE ENGINE COMPARTMENT. HE STATED THAT HE HAD JUST FUELED THE VESSEL AND THOUGHT THAT THIS MAY HAVE BEEN CONTRIBUTING TO THE SMELL OF GAS. HE THEN ATTEMPTED TO START THE ENGINE WHILE THE ENGINE COMPARTMENT WAS STILL OPEN. AT THIS TIME THE ENGINE Erupted INTO FLAMES. THE FIRE OVERCAME THE VESSEL BEFORE HE WAS ABLE TO ACCESS THE FIRE EXTINGUISHER. HE AND THE PASSENGER OF THE VESSEL THEN JUMPED INTO THE WATER. PRIOR TO SWIMMING TO SHORE HE WAS ABLE TO GET TO THE PLUG ON THE REAR OF THE VESSEL AND REMOVED IT, HOPING THAT THIS MAY CAUSE THE VESSEL TO SINK AND EXTINGUISH THE FIRE. HE AND THE PASSENGER WERE ABLE TO SAFELY SWIM TO SHORE.
