The first event occurred late at night on November 21, 2008, as the Grand Princess was sailing north along the west coast of Italy to dock at Civitavecchia, the port of Rome. She hit "rogue" waves and broke windows, lost power, and caused no end of chaos among the passengers, finally getting into port several hours late.
The other DrC and I boarded the Grand Princess in Civitavecchia on the 22nd. We interviewed several people who lived through the experience and saw the damage, which wasn't completely repaired until we reached Ft. Lauderdale, several weeks later.
The second event is this example, from the Associated Press via Breitbart. It reports three very large waves that hit a cruise ship based in Cyprus sailing off the coast of Spain, Two passengers were killed with flying glass from the broken windows.
