RedactedNarrative: Fuel vapor explosion during fueling.
   The boat had not been used in a very long time, and he had spent the last two days performing simple maintenance, and testing things out.  Needing gas, he took it to Annie's Bait and Tackle.  Operator 1 had to wait approximately 1 hour for Annie's to receive a fuel delivery.  After which, Operator 1   began refueling.  After he had pumped $250.00 worth, he thought to check the fuel level and battery charge.  The moment he turned the key, the explosion occurred; throwing him upward and lifting the cap off the hull.
  After the explosion, Operator 1 was able to, as quickly as possible, get himself off the boat, in fear of fire, or another explosion.  While being treated by first responders, he was able to inform the Fire Marshal that blower was on, and he didn't know what caused the explosion.
