RedactedNarrative: Operator of Watercraft #1 said he left his dock and was about halfway out in Lafayette Bay when he noticed black smoke coming from his instrument panel. He turned off the watercraft and checked for any hot wires. He did not find any. He started the watercraft again and at this point he noticed smoke coming from the motor housing of the watercraft. He turned off the watercraft and flagged down a passing boat. He boarded their watercraft, along with his dog. Shortly thereafter, his watercraft started on fire and due to the winds, which were approximately 15 mph coming from the south, his watercraft was pushed up against a dock at a residence directly into Watercraft #2. Watercraft #2 was tied up to the side of the dock and started on fire. It came undone from the dock. Both WC #1 and WC #2 were pinned against the dock and the fire spread to the dock, the dock canopy and Watercraft #3. All three watercraft were a TOTAL LOSS and there was also damage to the dock, dock canopy and a generator on the dock. There were no injuries and Operator #1 was wearing a life jacket. Alcohol was not a factor.
