The SS (RMS) King Orry (III) was a notable passenger steamer built by Cammell Laird at Birkenhead, launched on 11 March 1913. Constructed at a cost of £96,000, she had a registered gross tonnage of 1,600 GRT, with an overall length of 313 feet (95.4 meters) and a beam of 43 feet (13.1 meters). Her depth was 16 feet 11 inches, and she was designed for a speed of 21 knots. The vessel featured accommodations for 1,600 passengers and was powered by twin screws driven by two single-reduction geared turbine engines, which developed 9,400 indicated horsepower. This engineering design marked a significant advancement for the Isle of Man Steam Packet Company, as she was the first of their ships to be equipped with geared turbines, allowing a lower propeller speed while maintaining high turbine revolutions. King Orry’s maiden voyage commenced on 8 July 1913, operating on the Liverpool to Douglas route and achieving an average speed of 21.5 knots. She was the last ship built for the company before World War I and represented a step forward in marine engineering for the fleet. Her early service was briefly interrupted when she ran aground near Maughold, Isle of Man, on 17 July 1914, but she refloated after two hours and only sustained minor damage, returning to service within a week. With the outbreak of war, King Orry was requisitioned by the Admiralty in 1914, serving as an armed boarding steamer. She was armed with two 4-inch guns and operated primarily in Scapa Flow, conducting patrols, challenging suspect vessels, and intercepting contraband, including seizing a Norwegian steamer carrying iron ore. She also participated in intercepting German ships and supported the Royal Navy’s operations, including target towing after the Battle of Jutland. Notably, she was present at the German High Seas Fleet surrender in 1918, symbolizing the maritime efforts of the Isle of Man Steam Packet Company during the war. Post-war, she resumed passenger service but experienced a major peacetime incident when she stranded near the Rock Lighthouse in 1921, from which she was refloated after rescue operations. Extensively overhauled in 1934 and converted from coal to oil in 1939, King Orry returned to wartime service and was armed once again. During Operation Dynamo in 1940, she took part in the Dunkirk evacuation, successfully embarking over 1,100 soldiers. Her service ended when she was heavily damaged by German attacks, and after attempting to escape, she sank on 30 May 1940 in the English Channel. Her sinking marked the loss of a vessel with a distinguished service record, including her symbolic presence at the end of WWI and her significant role in both world wars.
