RedactedNarrative: Vessel 1 had a fire from an unknown source in the engine compartment.  The fire was put out by the vessel's fire suppressant system and portable fire extinguishers.  The engine and cabin sustained damage from the fire.  No injuries reported.
  
  Subject said they were out for a pleasure cruise.  He said he was operating the vessel at approximately 18 knots and had no warning of any problems or alarms until he smelled the odor of burning wires.  He said he opened the engine hatch and saw flames in the engine compartment.  He stated he used a fire extinguisher on the fire and thought it was out.  Subject said he went back to the helm to control the vessel but it had no power.  He said he returned to the engine hatch and saw the fire started smoking again which prompted him to activate the vessel’s Halon fire suppressant system.  
  
       The vessel was towed by Sea Tow Palm Beach to Jupiter Inlet Marina where I inspected and photographed the damage.  Subject wrote a written statement of his account of the incident. 
  
       While I took photos of the fire damage I noticed the two engine chambers had a white layer of powder on the floor and part of the engine.  There was also a film of white powder over the inside of the cabin.  Multiple parts to the engine were melted and bubbled.  The inside of the cover for the engine chamber was melted and burned black and brown.
