RedactedNarrative: The operator returned from a trip and tied the vessel to a dock. One of the passenger’s smelled smoke and the operator opened the front hatch on the rope locker. The operator could not find the source of the smoke so he went to the rear of the vessel to shut off the battery. He noticed flames and tried to put them out with a dry chemical fire extinguisher but could not put them out. The fire spread to fast and the owner got out of the vessel and exited the dock area to safety. The vessel burned completely gutting out the hull. This also caused extensive damage to the dock.
