Four people have been hospitalized after escaping a boat fire that broke out Friday evening off the coast of Long Beach, authorities said.

At 7:11 p.m., Long Beach Fire Department officials received a call about the fire on a 30-foot boat about 100 feet offshore between the Queen Mary and Hotel Maya, department spokesman Jake Heflin said.

Units arrived on scene at 7:15 p.m., Heflin said, and found seven people floating on a dinghy away from the main boat. The fire was extinguished, he said, and the boat was towed to an isolation dock in Alamitos Bay.

Two people suffered injuries that required “immediate” attention, while the other five had less serious injuries, Heflin said. He said three refused to be taken to a hospital.

Heflin said it was unclear what type of injuries the victims suffered or what caused the fire.

The boat fire did not damage any other structures or vessels in the area, he said.
