RMS Carinthia was an ocean liner built in 1956 as one of the four Saxonia class ships. She sailed for Cunard Line from her completion until 1968 when she was sold to Sitmar Line, rebuilt into a full-time cruise ship and renamed SS Fairsea. She sailed with Sitmar until 1988, when Sitmar was sold to P&O. She was renamed SS Fair Princess and sailed for Princess Cruises and P&O Cruises until 2000. She was then sold to China Sea Cruises and renamed SS China Sea Discovery. In 2005 or 2006 she was scrapped in Alang, India.

RMS Saxonia was a British passenger liner built by John Brown & Company at Clydebank, Scotland for the Cunard Steamship Company for their Liverpool-Montreal service. She was the first of four almost identical sister ships built by Browns between 1954 and 1957 for UK-Montreal service. The first two of these ships, Saxonia and Ivernia were extensively rebuilt in 1962/3 as dual purpose liner/cruise ships. They were renamed Carmania and Franconia respectively and painted in the same green cruising livery as the Caronia. Carmania continued transatlantic crossings and cruises until September 1967 when she closed out Cunard's Montreal service. She and her sister had been painted white at the end of 1966 and from 1968 Carmania sailed as a full time cruise ship until withdrawal after arriving at Southampton on 31 October 1971. In August 1973 she was bought by the Soviet Union-based Black Sea Shipping Company and renamed SS Leonid Sobinov. The ship was scrapped in 1999.
