RedactedNarrative: On 06-26-2022, i was advised of a boat fire that had occurred on 06-25-2022 at approximately 05:30 pm at quarterdeck marina in the sturgeon bay shipping canal. The sturgeon bay fire department put the fire out and the boat was relocated to an address on shore. 
  
  I met up with subject1 to look at the boat. Subject1 stated he had purchased the boat a couple weeks prior in the Milwaukee area. He stated he did not do any electrical work to the rear of the boat. He stated he had replaced the steering cable and noted there was some water in the bilge prior to putting it in the water that day. 
  
  He stated when he put the boat in the water, the bilge pump had turned on and off a few times. He had left the boat at the dock for the evening and was later called and advised it had started on fire. He stated someone on the dock had observed the boat smoking and used a fire extinguisher on it.
  
  The sturgeon bay fire department cut a hole in the starboard stern portion of the hull to put out all of the fire and to remove the battery which continued to arc. The boat had severe burn damage to the starboard stern corner. The wiring was melted and cut, the fuel inlet hose and scupper hoses were burned through. It appears as though the fire originated in the area of the starboard stern battery. There was also significant smoke damage to the interior of the cabin and it's contents.
