RMS Empress of Britain was a transatlantic ocean liner built by Fairfield Shipbuilding at Govan on the Clyde in Scotland in 1955–1956[1] for Canadian Pacific Steamships (CP).

This ship — the third of three CP vessels to be named Empress of Britain[2]—regularly traversed the trans-Atlantic route between Canada and Europe until 1964, completing 123 voyages under the Canadian Pacific flag.

[5] In November 1964, the former CP Empress of Britain was sold to the Greek Line; and the ship was renamed Queen Anna Maria.

This "Queen" was rebuilt with a new lido area at the stern and remeasured under Greek rules to 21,716 gross register tons, implying a significant reduction in size.

In fact her genuine tonnage had been increased by a superstructure extension at the stern and the measurement was an attempt to reduce dock dues.

In 1976, the former Greek Queen was sold to Carnival Cruise Lines; and the ship was renamed — this time as Carnivale.

In October 2005, The Topaz was inspected and found to be in immaculate condition, the steam turbines engines operating flawlessly.
