RedactedNarrative: Watercraft #1 was tied to the dock at the marina. The owner/operator was on board about 5:45 p.m. when he noticed smoke inside the boat. He grabbed a fire extinguisher and searched throughout the boat but didn't locate any fire. 
  
  He thought toward the aft of the watercraft, below the salon in a bedroom, the smoke seemed heavier. He shut off the power to the watercraft, and it kept getting smokier. At approximately 5:54 p.m., he had to leave the watercraft due to the smoke being too strong, and called 911. 
  
  Two other watercraft (#2 and #3) were tied off to the dock and were getting damaged by the heat from the fire. Marina staff removed WC #2 and WC #3 from the slips to minimize the damage. The fire department arrived and extinguished the fire. WC #1 was towed to the boat access to be removed from the water. Owner #1 stated the last voyage with the watercraft was on 8/3-8/4/19. 
  
  He hadn't noticed any issues with the boat He thought maybe the air conditioning unit was to blame, since he had noticed on the circuit box the unit was showing the circuit had been tripped. Duty officer was notified, and no apparent fuel leaked from the fire. There were no injuries and a life jacket was not being worn. Alcohol was not a factor. Watercraft #1 received heavy fire damage and was a Total Loss. 
  
  Watercraft #2 and #3 received heat related damage. There was also some damage to the dock, which is owned by the City of Red Wing.
