. She was based on the company's 1965-built , but with an enlarged hull, additional superstructure deck and improved interior layout. However, as the cost of building the Sagafjord had put her builders, Forges et Chantiers de la Mediterranee, out of business, the Vistafjord had to be built at a different shipyard. She was launched on 15 May 1972 and delivered to the Norwegian America Line exactly a year later on 15 May 1973. She is the last cruise ship to have been built in the United Kingdom.

) stripes. Following sale to Cunard she retained the grey hull colour, but her funnel was painted in the red/black Cunard colours and her mast white. A red "Cunard" text was later added to her superstructure. Coinciding with her renaming into Caronia in 1999 the ship's hull was repainted black. As Saga Ruby her hull was repainted dark blue and her funnel yellow, with a dark blue top and a narrow white stripe separating the two colours.
