A boat exploded after refueling at the Tega Cay Marina on Wednesday afternoon, sending four people to the hospital with serious injuries, according to witnesses and authorities.
The names and ages of those injured on the 37-foot cabin cruiser were not available. Accounts differed about the number of people on the boat when it exploded, but the state Department of Natural Resources said late Wednesday there appeared to be six.
Some of the boaters, including two adults and two boys, jumped from the boat and were pulled from the water by onlookers at the marina, according to authorities and witnesses.
One person was airlifted and three were taken by ambulance to Carolinas Medical Center in Charlotte. Two were later sent to the burn unit at UNC Hospitals in Chapel Hill, N.C.
A preliminary investigation determined the boaters refueled about 1:30 p.m. and had pulled away from the dock when it exploded, said Mike Channell, York County Emergency Management coordinator.
