HMS Gossamer was a Sharpshooter-class torpedo gunboat constructed at Sheerness Dockyard between 1889 and 1891. She measured 242 feet in length overall, with a beam of 27 feet and a draught of 10 feet 7 inches, displacing approximately 735 long tons. Her design aimed to improve upon earlier torpedo gunboats, featuring a raised forecastle for better seakeeping and increased speed and seaworthiness. She was powered by two triple-expansion steam engines, fueled by four locomotive boilers, intended to produce 4,500 indicated horsepower for a top speed of 21–22 knots. However, due to unreliable machinery, her actual performance was lower, reaching about 16.5 knots under natural draft conditions. Gossamer was armed with two 4.7-inch quick-firing guns on the centerline fore and aft, supported by four 3-pounder guns, and equipped with five 14-inch torpedo tubes—one fixed in the bow and two twin mounts—carrying three reload torpedoes. She had a crew of 91 men. Launched on 9 January 1890 and completed in September 1891 at a cost of approximately £54,490, Gossamer initially served in trials and participated in naval manoeuvres, including the Jubilee Fleet Review of 1897. She was refitted with Reed water-tube boilers in 1902 and served as a tender to HMS Pembroke in 1906. In 1909, she joined the Home Fleet and was converted to a minesweeper, removing her torpedo tubes. Throughout the early 1910s, she undertook various duties including fishery protection and patrols. During the First World War, HMS Gossamer was assigned to the Grand Fleet at Scapa Flow, conducting daily minesweeping operations and anti-submarine patrols, notably ramming and damaging the German U-41 in 1915. She remained active throughout the war, serving as part of the Second Fleet Sweeping Flotilla and later based at Oban with the 13th Minesweeping Flotilla. Gossamer was sold for scrap in 1920, marking the end of her maritime service. Her operational history reflects her adaptability from a torpedo gunboat to a minesweeper, contributing to Royal Navy fleet operations during a pivotal period.
