Here are two links to information about two famous ocean liners past and present.
RMS Queen Mary Long Beach California
The original Queen Mary took her maiden voyage in 1936 and was retired in 1967, sailing all the way around Cape Horn from Southampton England to Long Beach California. She was refitted into a floating hotel and tourist attraction.
Cunard Queen Mary 2 Luxury Liner
The Queen Mary 2, also referred to as the QM2, was launched in 2004 and is the largest ocean liner ever built. (There are two cruise ships which are larger, but they do not do transatlantic crossings.)
