Many ocean liners and cruise ships built from the 1950's onward sailed or at least lasted 40-50 years before being scrapped. Examples include the Kenya Castle/Amerikanis, Regal Empress, Empress of Britain/Topaz, Empress of Canada/Mardi Gras, Santa Rosa (1958), Southern Cross, the Saxonia class ships, SS Argentina and SS Brasil, Statendam (1957), RMS Windsor Castle, Maxim Gorky, Kungsholm (1966), Gripsholm (1957), Oriana (1960), Augustus, Transvaal Castle/Festivale, SS France/SS Norway, SS Oceanic, Starward/Aegean Queen, Cunard Adventurer, the Pacific Princess and Island Princess, Song of Norway, Nordic Prince, Sagafjord, Vistafjord, and Spirit of London. Furthermore, the SS Rotterdam and MV Bore sailed a little over 40 years and 50 years respectively before being preserved as hotel and museum ships. QE2 sailed a little under 40 years before ending up preserved as a hotel and museum ship in Dubai. Lastly, the Saga Sapphire is still going to another line despite being almost 40 years of age. So, the average life of a cruise ship went up from 25-30 years to a little over 40 years shortly before COVID-19. This is why the ocean liner Queen Mary 2 was built with a 40 year service life and Cunard is looking to extend that to 50 years.
