RedactedNarrative: While V1 was recreational cruising in the Gulf of Mexico in a southwest direction towards Longboat pass, all four occupants in V1 heard a loud bang and the engine turned off. Then suddenly, the stern hatch blew open up with flames. When the hatch blew open, it made contact with the rear standing occupant’s lower back torso causing a minor contusion, but didn’t require medical treatment. V1 operator was unable to get the fire extinguisher to work, so the flames began to engulf V1. All four occupants, while wearing personal flotation devices, abandoned V1 into the water.
  
  One occupant suffered a minor contusion to the lower back torso.
