RedactedNarrative: On May 29th 2018, while on vehicle patrol in the Bullfrog District of Glen Canyon National Recreation area I, U.S Park Ranger, along with District Ranger were requested to investigate a possible sunken vessel in Bullfrog Marina due to a vessel fire. We eventually located the vessel, a 24 foot white Bayliner, in Bullfrog dry storage. We made contact with the owner of the vessel. Owner stated that they did not take on any water but they were the vessel that called on Marine 16 for rescue the night before and that morning. Owner stated that he called Glen Canyon dispatch on his phone a few times but lost service while talking to them.
  
  I asked Owner to explain what happened the night before. Owner stated they were moored near the right arm of the Rincon Bay when around 1930 hours his wife by word of mouth, started to cook dinner with an alcohol stove that caught fire.
  
  Wife who was present at Bullfrog Dry Storage, stated that she spilled some of the alcohol fuel into the pan not knowing (unaware) there were slots in the corners of the pan, which allowed the alcohol to leak under the stove onto an icebox and some stored food. When Wife lit the fuel to start cooking she noticed flames flaring out of the side of the stove. She immediately turned off the stove and asked for the fire extinguisher. Owner attempted to use the extinguisher but it did not work. Later it was realized that the gage on the extinguisher was on empty and the extinguisher was not functional. Wife then stated she poured a gallon of milk on the stove to put the flames out. She then sat down on the seat next to the stove and noticed more flames under the stove in the cabinet area. She removed the stove top and saw that the icebox, made out of plastic and styrofoam, was on fire. Wife stated she attempted to use the fire extinguisher with no effect. At this time they started to scoop lake water using a half gallon pitcher and throwing it on the fire. Wife estimated they threw approximately 25 gallons of water on the fire to extinguish it. Wife mentioned that herself, subject1, her mother and her father were in the cabin when the fire started. Owner stated they all inhaled a good bit of smoke. All the other passengers on the vessel were on shore. Wife stated she had several burn marks on her arms but none were blistering. Wife denied any medical care at the time.
  
  Owner stated that at approximately 2130 hours. after they had cleaned up the vessel's cabin, they decided to drive the vessel back to Bullfrog Marina. Owner mentioned that he had two personal watercraft with him. He stated that he towed one of the personal watercraft and allowed his nineteen year old son to follow behind his vessel on their way back to Bullfrog Marina. Owner stated at approximately 2200 hours, both vessels ran aground on a sandbar near buoy 77. He stated that he was able to clear the props and follow the main channel buoy lights all the way back to Bullfrog Marina; arriving in Bullfrog Marina at approximately 0200 hours on May 29th 2018. When asked, Owner admitted that his navigation lights do not work. On land, while conducting an investigation of the accident, I conducted a vessel safety inspection of the vessel. It was documented that the vessel did not have any type IV personal flotation device, operating navigation lights, operable fire extinguisher, nor did it have any noise signaling device such as a horn, whistle or  bell. I issued Owner a federal violation notice for operating a vessel with no navigation lights displayed, which is a violation of 33 CFR 83 20. I also provided Owner with a boating safety brochure and educated him with verbal warning for the missing safety equipment on his vessel.
