The SS Mona's Queen (IV) was a notable passenger vessel operated by the Isle of Man Steam Packet Company from 1946 until 1962. Built by Cammell Laird in Birkenhead at a cost of £411,241, she was the second of six sister ships ordered by the company post-World War II. She was launched and commenced her maiden voyage on 26 June 1946, serving primarily between Douglas, Liverpool, and Fleetwood. Virtually identical to her sister, King Orry, Mona's Queen featured a slight difference in her main mast crosstrees, which were taller. She measured 2,485 gross register tons (GRT), with an overall length of 325 feet, a beam of 47 feet, and a depth of 18 feet. Her propulsion system provided a top speed of approximately 21 knots, powered by 8,500 indicated horsepower (i.h.p.). During her 1954 refit, she was fitted with radar technology, enhancing her navigational capabilities. In 1964, her tonnage was increased to 3,158 GRT, and she received significant upgrades, including the addition of a swimming pool and accommodation for 340 passengers. Mona's Queen’s primary service route was between Liverpool or Fleetwood and Douglas, where she provided reliable service for 16 years. Her final sailing from Fleetwood occurred on 11 September 1961, carrying 1,193 passengers. The vessel's end came when Fleetwood's berth was declared unsafe, and the company decided to dispose of her, especially with the advent of a new car ferry, the Manx Maid, and the closure of Fleetwood port. Her register was closed on 22 October 1962. Following her retirement, Mona's Queen was laid up at Barrow-in-Furness before being sold to the Chandris group of Greece in October 1962. She was renamed multiple times—Barrow Queen, Carissima, Carina, and Fiesta—and was adapted for cruising. As Carina, she carried 220 passengers and 60 cars, operating routes such as Piraeus to Brindisi via the Corinth Canal. After a significant rebuild in 1964, she emerged as Fiesta, accommodating 378 passengers and cruising the Mediterranean from Venice. She continued in service until she was scrapped in Perama in September 1981, marking her long and varied maritime career.
