V1 HAD A SMALL LEAK IN THE VESSEL. THE BILGE PUMP WAS NOT WORKING. THE OPERATOR OF THE VESSEL TOOK THE WIRES TO THE BILGE PUMP AND HOOKED THEM UP TO THE BATTERY. WHILE HOOKING UP THE BILGE PUMP THE OPERATOR DID NOT NOTICE THE FUEL AND GAS FUMES IN THE BILGE COMPARTEMENT. THE SPARK FROM THE BATTERY CAUSED THE EXPLOSION.
