Memphis Fire Department says the cause of the fire was an electrical problem in the engine of one of the boats docked in the marina.
Authorities say an on-duty fire fighter was burned his hand and a 66-year-old man was burned on his arm. Both were taken to the hospital and are expected to recover.
The marina and seven boats including a Memphis Fire & Rescue boat were damaged.
The total damage to the boats is estimated at more than half a million dollars and $2,000 to the marina
