RedactedNarrative: At approximately 1853 hours, I was on water patrol in the Haulover sandbar area. I saw thick black smoke rising from the Haulover fuel docks approximately ¼ mile away from my location across the sandbar. I advised dispatch of a vessel on fire and had them activate Miami Dade Fire Department and proceeded to the scene. 
  
  At approximately 1854 hours I arrived on scene along with a unit from Indian Creek Police Department and Coast Guard, who were all patrolling in the area. Fire Rescue arrived on scene at the same time. At this time the smoke and flames were controlled and there were no persons on board the vessel or any injuries. 
  
  Operator explained to me that he had completed fueling his vessel and attempted to start his engine when they failed to start. Operator attempted to start his engines for a second time; at that point he described an explosion from the stern of his vessel where the engine is located. Operator and Occupant jumped from the vessel into the water to not be in the confined space aboard the vessel with the flames and out of danger. They used a fixed ladder on the docks to climb back up onto to the docks. They began to put out the flames with a water hose and a fire extinguisher. Operator and Occupant had the fire extinguished prior to the Fire Department’s arrival. 
  
  Miami Dade Fire Department Engine 21 advised that the scene was safe and the fire completely extinguished. Captain advised of Miami Dade Fire Alarm number 140323060180. 
  
  No injuries were reported from either Operator or Occupant. The reported damage was contained to the stern of the vessel and the engine compartment. The blower system had not been properly maintained and did not provide proper ventilation of the engine compartment.
