RedactedNarrative: When I launched my vessel and finally arrived on scene, I observed a large vessel named Hang Em High of Fort Worth, Texas, on fire and burning very rapidly. I was able to make contact with the three occupants on board and identified them. 
  
  After verifying that everyone was okay and no one else was on board I gathered the preliminary information on what went wrong from the three of them. Operator told me that he and his friends were traveling from the Stuart area and were traveling west bound in the Caloosahatchee River towards Fort Myers. Operator told me that he powered down his vessel for some smaller vessels that were in the river in front of the Glades Boat Yard. Operator advised me that when it was safe, he tried to power back up but noticed the starboard side engine had lost power and RPM's. 
  
  Occupant advised me that when the vessel lost power, he opened up the engine room to see what was going on when a large plume of smoke came out of it. Occupant advised me that he observed the starboard engine's turbo blanket on fire and tried to put it out with a fire extinguisher but it got out of control before he could get it. Occupant advised me that he was in the process of turning on the Haylon System but it went off before he could turn the handle. Occupant advised me that the Haylon system failed to work. 
  
  All three subjects then advised me that they were trying to gather up their personal belongings when they tried to enter the cabin area and noticed that the floor was hot and soft. The subjects then told me that they all agreed that they needed to abandon ship before it was too late. The subjects then told me that they jumped from the burning vessel and swam to shore where Glades County Sheriffs Deputies later arrived on scene. The three subjects advised me that there was approximately 800 gallons of diesel fuel still on board at the time of the incident.
