RMS Queen Mary, Museum ship in Long Beach, United States

RMS Queen Mary is a retired British ocean liner, launched in 1934 at Clydebank and measuring 1,019.4 ft (310.7 m) overall, now permanently moored in Long Beach as a hotel, museum and convention space. Its black hull carries the name in white capitals on the bow, with a tan forward mast, three funnels banded orange-red below black tops, and rows of rectangular windows along the white superstructure. Inside, the three-storey cabin-class main dining room has tall wood-panelled walls, round tables with white cloths, red-upholstered chairs on a green, red and gold carpet, and a raised stage with dark curtains.

Construction began in December 1930 at John Brown & Company in Clydebank as Hull 534, halted in December 1931 during the Great Depression, and resumed in April 1934 after a government loan conditional on Cunard merging with White Star Line. Launched on 26 September 1934, she sailed her maiden voyage from Southampton on 27 May 1936. She took the Blue Riband in August 1936, lost it to Normandie in 1937 and regained it in 1938, holding it until 1952. From March 1940 she served as a grey troopship, carrying over 16,600 people on one 1943 voyage. Retired in 1967, she was bought by the City of Long Beach and opened to the public in 1971.

The name came from King George V: Cunard had planned to call the ship Victoria, but when asked to name it after Britain's "greatest queen" he suggested his wife, Mary. The interiors were fitted out in Art Deco style, and the cabin-class main dining room spanned three storeys, anchored by wide columns.

The decks and interiors can be toured through guided walks or by self-exploration, with some areas requiring stairs that lead upward. Cabins are available for overnight stays, and several restaurants offer meals with views of the harbor.

The navigation bridge preserves the original steering instruments and brass telegraphs that once transmitted orders to the engine room. These devices still show the handwork and mechanics that were used before digital navigation.
