HMS Captain was arguably one of the most spectacular, innovative ships of the period, owned by the British Royal Navy. It had mixed propulsion and a 900 NHP output from two horizontal four-cylinder engines, eight rectangular boilers and two propellers, as well as a large area with sails.
The boat whose 97.5 metre long hull was steel, reached speeds of 15.2 knots and had a displacement of 7,767 tons. It had been built in 1869 at the Lairds shipyard in Birkenhead (United Kingdom) and had four 305 mm cannons and two other 178 mm ones.
Its captain, Hugh Talbot Burgoyne, could do nothing since the boat overturned as a result of not being seaworthy due to its design.
Under sail, it could not overcome the list produced by the wind in this area of the European Atlantic and sank. There were 483 casualties. Out of a crew of 501, only 18 were saved.
Despite being one of the most innovative ships of its time, the H.M.S. Captain capsized because it was not seaworthy due to its design.
