HMS Royalist was a Satellite-class composite screw sloop of the Royal Navy, constructed at Devonport Dockyard and launched on 7 March 1883. As a composite vessel, she featured an iron frame with wooden planking, a design that combined traditional wooden shipbuilding with iron reinforcement. Notably, she was the only ship of her class fitted with an armored deck, setting her apart within her class. Her propulsion system consisted of a horizontal compound-expansion steam engine built by Maudslay, Sons and Field, which generated 1,470 indicated horsepower and drove a single screw propeller. She was also equipped with masts and spars for a barque rig, enabling sail-powered maneuvering when needed. Royalist's armament included a uniform outfit of eight BL 6-inch/100-pounder Mk II guns, complemented by a light gun and four machine guns, differing from her sister ships that carried a mix of 6-inch and 5-inch breech-loading guns. She was initially commissioned in 1886 and served primarily in the Cape of Good Hope and Australia Stations, where she operated in the Pacific region overseeing British Western Pacific Territories. Under Captain Edward Davis, Royalist undertook a significant survey mission from 1891 to 1892, visiting islands such as Vanuatu, New Caledonia, Papua New Guinea, Solomon Islands, Gilbert Islands, Marshall Islands, and Ellice Islands. During her service, she was involved in notable actions, including a punitive expedition in 1891 following the murder of trader Fred Howard on Uki Island and the proclamation of the Gilbert Islands as a British Protectorate in 1892. Her reports from the Ellice Islands detailed local trading activities and the islanders' desire for British protection. Royalist also participated in operations during the Samoan civil unrest in 1899, reflecting her active role in regional affairs. In 1900, she was hulked and repurposed for harbor service, later renamed Colleen in 1913. The vessel's service extended into World War I, during which Antarctic explorer Tom Crean served as boatswain aboard her. Transferred to the Irish Free State in 1923, Colleen was eventually broken up in 1950, marking the end of her maritime service.
