Rogue wave sequence showing 60-foot plus wave hitting tanker headed south from Valdez, Alaska. The ship was running in about 25-foot seas when a monster wave struck it broadside on the starboard side. The sequence shows the wave striking the OVERSEAS CHICAGO, rolling over the deck, and then the ship heeling to port with water rushing off. A lesser ship could have been lost.
