The MV Leinster was a notable passenger ferry constructed by Harland and Wolff in 1937 for the British and Irish Steam Packet Company. Designed to serve the Irish Sea route, she initially operated on the Belfast-Liverpool service, chartered to the Belfast Steamship Company until a new Dublin terminal was completed. In 1938, she and her sister vessel, MV Munster, commenced their intended route between Liverpool and Dublin. These ships were the largest in the Coast Lines fleet at the time, distinguished by their substantial size, although their original buff hulls were later repainted dark green. Unlike earlier vessels, Leinster and Munster lacked cattle capacity, a significant cargo on the Dublin route, leading to the construction of specialized cattle carriers such as Kilkenny and Dundalk. During World War II, the MV Leinster was repurposed from passenger service into a hospital ship and subsequently a troop carrier, reflecting her versatility and importance during wartime. After the war, she underwent refitting and was renamed Ulster Prince (II) to serve the Liverpool-Belfast route, alongside Ulster Queen, which was one of the few of her wartime trio to survive and return to peacetime operation. In 1966, she was renamed Ulster Prince I to accommodate her replacement, the new car ferries MV Irish Coast and MV Scottish Coast. Following her withdrawal from service in October 1966, the vessel's role on the Irish Sea was succeeded by these newer ships. The following year, she was sold to Epirotiki Line and renamed Odysseus. Her later years saw her used as accommodation at Kyle of Lochalsh and Glasgow, before she was ultimately scrapped at Faslane in 1980. Throughout her career, MV Leinster/Ulster Prince played a significant role in Irish Sea passenger transport and maritime history, adapting through wartime service and postwar commercial use before her final demise.
