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 was sold to the Greek Line; and the ship was renamed SS Queen Anna Maria.

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

In fact her genuine tonnage had been increased by 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 the SS Carnivale.

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