RMS Queen Mary is a retired British ocean liner that sailed primarily on the North Atlantic Ocean from 1936 to 1967 for the Cunard-White Star Line and was built by John Brown & Company in Clydebank, Scotland. Queen Mary, along with RMS Queen Elizabeth, were built as part of Cunard's planned two-ship weekly express service between Southampton, Cherbourg and New York. The two ships were a British response to the express superliners built by German, Italian and French companies in the late 1920s and early 1930s.

Queen Elizabeth 2 (QE2) is a retired British ocean liner converted into a floating hotel. Originally built for the Cunard Line, the ship, named as the second ship named Queen Elizabeth, was operated by Cunard as both a transatlantic liner and a cruise ship from 1969 to 2008. She was then laid up until converted and since 18 April 2018 has been operating as a floating hotel in Dubai.
