Multiple people were injured and four had to be hospitalized after a 30-foot boat caught fire in Long Beach, California, Friday.

First responders arrived at 7:15 p.m. and found the boat in flames near the permanently moored ocean liner Queen Mary. 

Seven people on a dinghy were rescued. Of those, two suffered injuries that required immediate attention and two joined them at the hospital. The other three refused treatment, Long Beach Fire Department Capt. Jake Heflin told the Los Angeles Times.

No other watercraft or nearby structures were affected by the boat fire. The cause of the blaze is being investigated.

A Reddit user on a boat ride in the area posted a purported video of the fire and reported hearing “a loud boom and then [turned] around and saw a boat on fire with someone on it.”

The burning boat was towed to a dock in Alamitos Bay around 6 miles away, Capt. Heflin told Long Beach Watchdog.
