Police on Saturday were investigating a speedboat crash that killed a man in his 50s Friday.

The man was found in the hull of a damaged 21-foot power boat against the east end of the federal breakwater about 1 1/2 miles from Ballast Point Brewing.

The name of the boater, a man in his 50s, will be released pending notification of next of kin, according to Lt. David Smith of the Los Angeles County coroner’s office.

Crews responded about 4:45 p.m. Friday to an emergency radio channel distress call reporting the vessel overturned, according to Long Beach Fire Department spokesman Brian Fisk.

The boat was discovered against rocks that are part of the breakwater, according to the fire department. Witnesses saw paramedics performing life-saving measures on the victim at a dock near Ballast Point, but the unresponsive man was later pronounced dead at a hospital, according to the Long Beach Police Department.

Drones and divers were deployed to search for more potential victims, but none were found, said Long Beach Fire Department spokesman Brian Fisk.

“The recovery phase is over and now they’re trying to determine what happened,” Fisk said.
