HMS Lord Clyde was the name ship of the wooden-hulled of two armoured frigates built for the Royal Navy (RN) during the 1860s. She and her sister ship, , were the heaviest wooden ships ever built and were also the fastest steaming wooden ships in the RN. Lord Clyde was initially assigned to the Channel Fleet in 1866, but was transferred to the Mediterranean Fleet in 1868. The ship suffered engine problems throughout her career and it needed to be replaced after only two years of service. She rejoined the Mediterranean Fleet in 1871, but was badly damaged when she ran aground the next year. When Lord Clyde was under repair, her hull was found to be rotten and she was sold for scrap in 1875. Design and description HMS Lord Clyde was long between perpendiculars and had a beam of . The ship had a draught of forward and aft. She displaced and had a tonnage of 4,067 tons burthen. Lord Clyde had a very low centre of gravity which meant that she rolled very badly; she was said to be the worst roller in the Victorian fleet. This characteristic was so dramatic that when the rolling propensities of ships were compared, it was usual to say "as bad a roller as the Prince Consort", the Lord Clydes being beyond compare. Lord Clyde generally performed worse than did her sister ship, Lord Warden. In sea trials in 1867 with , Lord Clyde was rolling her gun ports under, while Bellerophon could have fought her main armament in safety. She was, however, very handy and sailed well in all weathers under sail or steam; her first captain reported that she was "as handy as a frigate". Her crew consisted of 605 officers and ratings. Propulsion The ship had a single two-cylinder trunk steam engine, made by Ravenhill and Hodgson, that drove a single propeller using steam provided by nine rectangular boilers. The engine, the largest and most powerful yet built, produced which gave Lord Clyde a speed of under steam. The severe vibration of the engine, coupled with the flexibility of the wooden hull, caused major problems during the ship's career. After only two years, the engine was worn out and everything but the condensers and shafting had to be replaced. She carried a maximum of of coal. Lord Clyde was ship-rigged with three masts and had a sail area
