The SS (RMS) Tynwald (III), No. 95755, was an iron passenger steamer constructed by Fairfield at Govan in 1891. She was notable for being the first Isle of Man Steam Packet Company vessel equipped with a triple-expansion engine, marking a technological advancement in their fleet. Launched on 11 May 1891, Tynwald featured full electric lighting, a first for the company, enhancing passenger comfort and safety. She measured 265 feet between perpendiculars, with a beam of 34 feet and a depth of 14 feet, and had a gross register tonnage of 937. Her propulsion system comprised two boilers operating at 160 PSI, each fired by eight furnaces, powering two triple-expansion engines that produced 3,800 indicated horsepower, enabling her to reach speeds of 18 knots. Tynwald was designed to serve as a winter vessel on the Douglas–Liverpool route, with summer duties extending to the Douglas–Ardrossan service and later, the Douglas–Whitehaven route, inaugurated in July 1912. She could carry up to 679 first-class and 225 third-class passengers, totaling 904, with a crew of 50. Her passenger accommodations and speed made her competitive with larger ships like the Queen Victoria. Her service record included notable rescues, such as assisting the Mona's Isle after it ran aground in 1892, and aiding the liner SS City of New York in 1917 after it was torpedoed by a German submarine. During World War I, she maintained commercial service rather than military duties, transporting German prisoners interned at Knockaloe and frequently operating through mine-threatened waters near Liverpool under the command of Captain Cojeen. Throughout the war, Tynwald encountered numerous hazards, including floating mines and submarine threats, yet she remained unscathed. Post-war, she continued leisure and excursion services, notably from Blackpool. In 1933, plans to scrap her were canceled; instead, she was purchased and converted into a private yacht, renamed Western Isles in 1935, and later requisitioned as an auxiliary vessel during WWII, renamed Eastern Isles in 1941. She served as an accommodation ship until 1946, after which she was returned to her owner, but the extensive repairs required post-war rendered her unviable. Ultimately, she was sold in 1951 and towed to Spezia for breaking, marking the end of her maritime service.
