The probable cause of the capsizing was the chief officer’s mistake while entering ballast quantities into the stability calculation program, the NTSB report said. That meant the vessel had less stability than the chief officer calculated, the report said. The operator of the ship also had no procedures to verify the chief officer’s calculations, so the operator and master of the ship didn’t know the Golden Ray was sailing without meeting stability requirements, the NTSB said.
