A fiery explosion on board a boat in Florida injured four people — including a woman who had to be airlifted to a hospital with severe burns, officials said.

The terrifying incident took place at Halifax Harbor Marina in Daytona Beach at around 1:15 p.m. Sunday and was captured on a surveillance video that was aired by the station ClickOrlando.

The dramatic footage shows the 34-foot vessel dubbed Jumper being rocked by a powerful blast, causing debris to fall into the water and sending plumes of thick black smoke into the sky.

According to the Daytona Beach Fire Department, the boat had just finished refueling and the people on the vessel were attempting to start its engine when the explosion occurred.

A 50-year-old woman was transported by helicopter to a hospital in Orlando to be treated for burns to the right side of her body.

The three other boaters received medical help at the scene and refused hospitalization.

“It’s sad to see more than anything,” Ilene Jones told ClickOrlando. “Somebody definitely had a bad day.”

Firefighters who were called to the scene were able to put out the flames engulfing the boat, which was left badly damaged and partially charred.

Officials said the owner of the boat believes the explosion was possibly set off by gas vapors, but the exact cause of the blast is under investigation.
