RedactedNarrative: INITIAL REPORT
  On August 3, 2016 at approximately 1637 I (Ranger), received a report from park dispatch of a vessel in distress in the vicinity of Last Chance Bay. The report was for a private vessel that had capsized and begun to sink in the storm. I arrived on scene at approximately 17:28 hours to find a large debris field and that the vessel had already sunk. I subsequently retrieved the GPS coordinate of the center of the debris field (37 degrees 05.019 North, 111 degrees 14.502 West). The occupants of the vessel had been picked out of the water by nearby boats and I directed the bystanders to begin collecting the debris before they sank.
  
  INVESTIGATION
  I conducted a field interview with the operator/owner of the vessel. OPERATOR1 stated that they had been floating and relaxing in one of the coves in Last Chance Bay when he began to drifting towards the rocks. OPERATOR1 attempted to start the engine but was unable to start it and had a friend, on a jet ski, pull him away from the rocks, and then disconnected from the jet ski that was towing them. At approximately 1600 hours a sudden micro burst came down and the waves from the storm began to come over the bow. Despite efforts using the vessels bilge pump, the water continued to flow over the bow and fill the boat. OPERATOR1 instructed everyone on board to don a PFD before the vessel began to capsize and sink. The boat sank stern first and was held up for a few minutes by an air pocket in the bow before sinking. A passing boat picked the occupants of the vessel out of the water and brought them to a nearby house boat until I arrived.
  
  DISPOSITION
  I have determined through my field interview that the cause of the accident was a combination of the vessel being unable to start its engine to maneuver out of the storm, and the sudden onset of the storm resulting in the vessel capsizing and sinking.
  
  Time Spent on report: 2 hours on scene and 1 hour spent on report.
