Reina del Mar was a 20,334 GRT liner which was built by Harland & Wolff in 1955 for Pacific Steam Navigation Company (PSNC).

[1] Launched on 7 June 1955, it offered modern amenities, like private plumbing in passenger cabins and air-conditioning throughout the ship.

[1] Some passengers were on the ship from one port to another, which may have been as few as a day or two, while others traveled several weeks for the entire trip between Liverpool to Valparaíso, Chile.

[2][3] Based in Southampton, the liner travelled to ports in Scandinavia, the Mediterranean, Canary Islands, West Africa between April and October.

[2][3] As was the case for many of the older liners, its business suffered due to the oil crisis of 1973–1974,[3] and it was retired in April 1975[1] and sold that year to Tung Cheng Steel of Taiwan.
