HMS Amethyst was the lead ship of the Amethyst-class corvettes built for the Royal Navy in the early 1870s. She measured 220 feet (67.1 meters) in length between perpendiculars, with a beam of 37 feet (11.3 meters) and a draught of 18 feet (5.5 meters). The vessel displaced approximately 1,934 long tons (1,965 tons) and had a burthen of 1,405 tons. Her crew numbered around 225 officers and ratings. Constructed with a wooden hull, Amethyst lacked watertight transverse bulkheads, a characteristic that distinguished her from iron-hulled contemporaries. Propulsion was provided by a single two-cylinder horizontal compound expansion steam engine, built by J. & G. Rennie, which drove a 15-foot (4.6 meters) propeller. The engine produced 2,144 indicated horsepower, allowing a maximum speed of about 13.244 knots (24.5 km/h). She carried 270 long tons (270 tons) of coal, sufficient for steaming between 2,060 and 2,500 nautical miles at 10 knots. Additionally, Amethyst was rigged as a ship with an 18,000 square foot sail area, featuring iron lower masts and wooden upper masts, which endowed her with excellent sailing qualities. During a 1878 refit, she was re-rigged as a barque, and her propeller could be hoisted into the stern to reduce drag under sail. Armament initially consisted of twelve 64-pounder 71-cwt rifled muzzle-loading guns on the broadside, with two lighter 64-cwt guns as chase guns. In 1878, her armament was updated with all 64-cwt guns replacing the previous 71-cwt types. Laid down at Devonport Dockyard on 28 July 1871, she was launched on 19 April 1873 and completed that July, costing around £77,000. HMS Amethyst participated actively in notable events, including the Third Anglo-Ashanti War and a significant engagement off Peru. In May 1877, she fought in the Battle of Pacocha against the Peruvian ironclad Huáscar, making her the only British wooden sailing ship to engage an armored opponent. Although her gunfire was ineffective against the ironclad, the battle ended with Huáscar's retreat and subsequent surrender. Her service included serving as the senior officer's ship on the South American station and later on the Pacific Station. She was finally sold for scrap in November 1887, marking the end of her distinguished maritime career.
