Mount Pleasant Fire Chief Mike Mixon said a fellow boater reported hearing the explosion around 9 p.m. By the time firefighters arrived, a small fire had been extinguished in the engine room.
Three people on board the boat were transported to a hospital, Mixon said, and a fourth refused an ambulance but later sought treatment. Some of the injuries were “pretty severe,” but none appeared life-threatening, according to Mixon.
It’s not yet clear what caused the fire, but Mixon said it appeared to be a fueling accident. It’s the only boat explosion the department has responded to in recent memory, according to Mixon.
The boat remained afloat, and there was no serious damage to surrounding vessels or property, according to a marina manager.
