RedactedNarrative: On July 15, 2018, a single vessel, identified as a 1998 Egret, was anchored in the Taylor Creek waterway, Fort Pierce, Florida.  The vessel exploded and became engulfed in flames.  
   vessel owner/operator was and three additional passengers were on the vessel. All persons evacuated the vessel without injury.
  
       Operator advised, prior to the vessel fire, he had made two unsuccessful attempts to start the engine.  On the third attempt, there was an explosion and flames at the engine.  All persons jumped into the water and swam to a nearby sandbar.
  
       During an examination of the vessel, I noted the vessel passenger compartment was charred entirely.  Two of seven visible hatches, appeared to have been blown open.  The vessel was equipped with an outboard engine along with three batteries, and a built-in forty gallon fuel tank.
