Duke of Argyll
The Heysham-Belfast route was closed on 5th April, 1975, with the Duke of Argyll running the final sailing to Belfast. After brief service at Holyhead she was sold to Greece as Neptunia for Libra Maritime. In 1987 she was renamed Corinthia for Hellenic Maritime Lines (HML).
Following her career in Greek waters the ship arrived in Hong Kong as the Faith Power in March 1994. By 1995 she had been renamed Fairy Princess but in February of that year was put up for sale by the Supreme Court of Hong Kong and renamed Zenith.
