RedactedNarrative: BOAT OCCUPANTS NOTICED SMOKE COMING FROM THE ENGINE COMPARTMENT. THE OPERATOR OF THE BOAT OPENED THE COMPARTMENT AND THE SMOKE INCREASED SIGNIFICANTLY AND THEN THE COMPARTMENT BURST INTO FLAMES. BOTH OCCUPANTS JUMPED INTO THE WATER AND WERE UNINJURED. THE BOAT SUSTAINED SIGNIFICANT FIRE DAMAGE AND WAS A TOTAL LOSS. DAMAGE WAS TOO SIGNIFICANT TO DETERMINE THE CAUSE OF THE FIRE, THOUGH IT IS SUSPECTED EQUIPMENT MALFUNCTION. THE OCCUPANTS STATED THAT THEY THOUGHT THE ENGINE HAD BEEN MAKING AN ODD NOISE PRIOR TO THE INCIDENT.
