HMS Decoy was an Ariel-class composite gunboat of the Royal Navy, launched on 12 October 1871 from Pembroke Dockyard. Designed by Sir Edward Reed, the Chief Constructor of the Royal Navy, she represented a significant development as part of the first class of gunboats constructed using composite methods—combining iron frames with wooden planking—enhancing durability and seaworthiness for colonial and coastal operations. The vessel measured approximately 130 feet in length, with a beam of around 22 feet, and was powered by a steam engine complemented by a three-masted barquentine rig, allowing versatility in propulsion and sailing. Her armament comprised two 6-inch (150 mm) 64-pounder muzzle-loading rifles and two 4-inch (100 mm) 20-pounder Armstrong breech-loading guns, all mounted on traversing carriages, enabling flexible targeting during combat. HMS Decoy served primarily in West African waters, supporting British operations on the Gold Coast. She was deployed alongside vessels such as Druid and Argus, and notably participated in the bombardment of Bootry, showcasing her role in colonial military actions. Her service extended to involvement in the broader conflict during the Third Anglo-Ashanti War in 1873. A significant event in her service was her participation in the 1882 Bombardment of Alexandria, where she was part of the naval and military forces supporting British interests during the conflict. During this operation, she, along with Argus, Isis, and Beacon, was involved in blockading Damietta, demonstrating her role in larger Mediterranean and Egyptian engagements. Due to rapid technological advancements, HMS Decoy quickly became obsolete, and her active service lasted only until 1885, when she was sold at Malta. Her short but active career highlights her importance as one of the pioneering composite gunboats and her contribution to British naval operations during the late 19th century.
