Seven people were injured in a boat explosion Sunday evening after refueling on Cheat Lake. The boat had taken on 30 gallons of fuel at the Edgewater Marina; the explosion happened when the operator went to start the boat to leave the marina. Investigators believe a spark from the boat’s starter was the likely ignition source. Seven of eight people on the boat were transported to Ruby Memorial Hospital; two of those people were later transferred to the West Penn Burn Center in Pittsburgh.
