A 34 foot gas inboard 1988 Wellcraft cabin cruiser had just refueled.  The operator stated he did use the blowers.  He started both engines and drifted away from the dock.  The port engine stopped and the operator attempted to restart.  As the engine cranked, an explosion occurred.  The engine room hatch collapsed and one occupant fell into the burning engine room.  The operator stated all jumped or were thrown overboard and he threw them life vests.  There were three adults and nine children aboard.  6 victims suffered burns, 4 of them serious burns (1st or second degree primarily on feet, and legs.   

 The operator was cited for operating a vessel without current registration.   Subsequent investigation revealed a strong smell of gasoline throughout the vessel.  Two occupants stated fuel was spilled in the boat while at the gas dock and water was used to remove the gas.  Several photographs were taken by the NRP investigator and showed a vessel with apparently poor maintenance in the engine area -- (corrosion, rust, debris).
