The victim’s age was initially given as 69.

The accident was reported to the Orange County Sheriff’s Harbor Patrol just before 3 p.m. as passengers aboard his large double-decker boat tried to save their captain, Sheriff’s Lt. Steve Gil told the Orange County Register.

The injury happened after the man climbed into the water for a swim close to the open waters near the jetty, Gil told the Register.
