Something went 'catastrophically wrong' in San Francisco Bay. What caused deadly boat sinking?

Something went 'catastrophically wrong' in San Francisco Bay explains the rescue effort and the ongoing investigation into a deadly boat sinking near the Golden Gate. James Smith, a veteran seaman and captain of the charter fishing boat California Dawn, said he heard a radio distress call Tuesday near Alcatraz Island and saw rapid sinking. Rescuers pulled 17 people to safety, but the man who received CPR was pronounced dead after reaching shore. On Thursday, a female passenger was recovered and also pronounced dead, while two passengers remained missing. The 49-foot, three-level vessel, called Volare, carried 20 passengers for a memorial. Capt. Jarod Toczko of the U.S. Coast Guard said survivors reported a wave hit the boat, causing it to list and roll over, but investigators say a single wave is unlikely. The likely cause will be determined after officials retrieve the boat from the ocean floor.
