RedactedNarrative: While patrolling we heard a loud explosion at the fueling docks located at the Lake Blackshear Marina.  We immediately responded to the area and discovered a white/maroon Chaparral ski boat, Georgia Registration GA6677JB with smoke and flames coming from the engine compartment.  All four occupants had abandoned the vessel and swam safely to nearby vessels.  
  
  The occupants of the vessel consisted of 2 adult males and 2 children one female and one male.  
  
  The driver of the vessel was Operator.  Occupant1 was seated in the passenger’s seat directly across from the driver’s seat while both children were seated in the bow at the time of the explosion.  
  
  We extinguished the flames on the vessel and towed it safely away from the Lake Blackshear Marina, to the boat landing in Boy Scout Slough.  The four occupants were also transported to the boat landing in Boy Slough.  Crisp County Fire and Crisp County EMS arrived at the landing, and checked the four occupants of vessel.  No injuries were noted, all occupants stated, they were fine.  
  
  While interviewing Operator., he stated after filling up with gas, he attempted to start the motor 4 or 5 times until it finally started and just a few seconds later it exploded.  Occupant1 stated once the boat started, it ran for a few seconds, the vessel then exploded and all four occupants jumped out of the boat and started swimming. 
  
  The vessel sustained cracks in the fiberglass on both the stern and bow of the vessel as well as on the starboard side in front of the console.  The drivers console was blown from its mount and the engine compartment was damaged by fire.  After examining and photographing the vessel, it was turned over to Arabi Boat Works for transport.
