RedactedNarrative: On 10/07/18 at approximately 6:45pm ten people were aboard a 1996 26’ Thunderbird Cabin motor boat in the Intracoastal waterway in Boca Raton. The vessel lost power near Silver Palm Park and the Operator 1 attempted to restart the vessel. Gasoline vapors contained in the inboard engine compartment caused an explosion. As a result, the engine door hatch blew open and flames exited it. Occupant 1 (Injured occupant) was standing directly over the hatch as the explosion occurred. As the hatch fell closed, Occupant 1’s right arm became trapped under it. The other occupants aboard the vessel came to Occupant 1’s aid and lifted the hatch off her arm.  A fire extinguisher aboard the vessel was used to extinguish the flame. One occupant aboard the vessel, Occupant 1 received lacerations and burns to her right hand and arm. No other occupants were injured. No citations were issued.
