HMS Captain was an unsuccessful warship built for the Royal Navy due to public pressure. She was a masted turret ship, designed and built by a private contractor against the wishes of the Controller's department. The Captain was completed in April 1870 and capsized in September 1870 with the loss of nearly 500 lives because of design and construction errors that led to inadequate stability.

Background
The history of the Captain can be traced back to the Crimean War and the experiences of British captain Cowper Phipps Coles in 1855. Coles and a group of British sailors constructed a raft with guns protected by a turret and used the small boat, named the Lady Nancy, to shell the Russian town of Taganrog in the Black Sea. The Lady Nancy "proved a great success"[1] and Coles patented his rotating turret after the war. Following Coles patenting, the British Admiralty ordered a prototype of Coles' design in 1859, which was installed in the floating battery vessel, HMS Trusty for trials in 1861.
The trials with the Trusty impressed the Admiralty, and it ordered a coastal defense vessel, HMS Prince Albert, to be built with four of Coles' turrets and a wooden 121 gun first rate ship-of-the-line under construction, HMS Royal Sovereign to be converted to a turret ship. The Prince Albert was completed with four turrets mounting single 12-ton 9 inch guns and 4.5 inch thick armour plate on the hull. The Royal Sovereign had five 10.5 inch, 12.5 ton guns in one twin and three single turrets.[2]
Both ships were flush deck with only a jury rig, and could only operate as coastal service vessels.[3] However, the Admiralty, although impressed with Coles' rotating turret, required oceangoing vessels to protect its worldwide empire. Unfortunately for Coles, engine technology had not yet caught up with his designs and consequently oceangoing ships required sails. Combining rigging, masts and turrets proved complicated if rigging was not to impede the turrets' arc of fire.
In early 1863 the Admiralty gave Coles permission to work with Nathaniel Barnaby, head of staff of the Department of Naval Construction, on the design of a rigged vessel with two turrets and three tripod masts. However, in June 1863 the Admiralty suspended progress on the vessel until the Royal Sovereign finished her trials.
In 1864, he was allowed to start a second project: a rigged vessel with only one turret and based on the design of HMS Pallas, and was lent the services of Joseph Scullard, Chief Draughtsman of Portsmouth Dockyard.[2]
The next year, 1865, a committee established by the Admiralty to study the new design concluded that while the turret should be adopted, Coles' one-turret warship design had inadequate fire arcs.[1] The committee proposed a two-turret fully rigged vessel with either two 9" (12 ton) guns per turret, or one 12" (22 ton) gun per turret. The committee's proposal was accepted by the Admiralty, and construction was started on HMS Monarch. Monarch's two turrets were each equipped with two 12" (25-ton) guns.
Stunned by the committee's decision to cancel his single-turret ship and his proposal for a two-turret vessel, and objecting to the Monarch's design, Coles launched a strong campaign against the project, attacking Robert Spencer Robinson, Controller of the Navy, and various other members of the committee and the Admiralty. So vociferously did Coles complain that in January 1866 his contract as a consultant to the Admiralty was terminated. At the end of January, his protestations that he had been misunderstood led to his being re-employed from 1 March 1866.[2] Further, Coles lobbied the press and Parliament and was eventually able to force the Admiralty to allow him to build his own two-turret design.
Design and construction
In May 1866, Coles informed the Admiralty of his selection of Laird Brothers' Merseyside yard, for the builder of the warship. The Merseyside yard had already built several successful ironclads and readily accepted the challenge of building a vessel to Coles' specifications.[1] To prevent the rigging from being damaged when the guns fired through it, it was attached to a platform mounted above the gun turrets known as the hurricane deck instead of brought down to the main deck. Tripod masts were also used to minimise standing rigging.
The design called for the ship to have a low freeboard, and Coles' figures estimated it at 8 feet. Both the Controller Vice-Admiral Sir Robert Spencer Robinson and the Chief Constructor Edward James Reed raised serious concerns. Robinson noted the low freeboard could cause flooding issues on the gun deck, and Reed criticised the design in 1866 for being both too heavy and having too high a centre of gravity. On the latter, Reed noted that it would cause issues "especially as it is proposed to spread a large surface of canvas upon the Captain".[4] As the design neared completion, the First Lord of the Admiralty, Sir John Pakington, wrote on 23 July 1866 to Coles approving the building of the ship, but noting that responsibility for failure would lie on Coles' and the builders' lap.[2]
In November 1866, the contract for the HMS Captain was approved and the design was finished. She was laid down 30 January 1867 at Cammell Laird, Birkenhead, England, launched 27 March 1869 and completed in March 1870.
Insufficient supervision during the building, partly due to Coles' protracted illness,[5] meant that she was 735 long tons (747 t) heavier than planned.[6] The designed freeboard was just 8 feet (2.4 m) and the additional weight brought it down to just 6 feet 6 inches (1.98 m), and forced her to float 22 inches (0.56 m) deeper than expected.[7] The center of gravity of the vessel also rose by about ten inches during construction. Reed raised havoc over the problems with the freeboard and the center of gravity, but his objections were overruled during the Captain's trials.[6]
She was commissioned on 30 April 1870 under Captain Hugh Talbot Burgoyne, VC. During trials in the following months, the Captain seemed to be everything that Coles promised and won over many followers. In trials versus the Monarch, she performed well and returned to sea in July and August, travelling to Vigo, Spain and Gibraltar in separate runs.
Sinking
On the afternoon of 6 September 1870 Captain was cruising with the Channel Squadron of 11 ships off Cape Finisterre. The ship made 9.5 knots under sail in a force six wind, which was increasing through the day. The commander in chief was onboard to see her performance and speed had risen to 11-13 knots before he departed. Not being accustomed to ships with such low freeboard, he was disturbed to note that at this speed with the strengthening sea, waves washed over the weather deck. The weather worsened with rain as the night progressed and the number of sails was reduced. The wind was blowing from the port bow so that sails had to be angled to the wind, speed was much reduced and there was considerable force pushing the ship sideways. As the wind rose to a gale, sail was reduced to only the fore staysail and fore and main topsails.[8]
Shortly after midnight when a new watch came on duty, the ship was heeling over eighteen degrees and was felt to lurch to starboard twice. Orders were given to drop the fore topsail and release ropes holding both topsails angled into the wind.[9] Before the captain's order could be carried out, the roll increased and she capsized and sank with the loss of around 480 lives, including Coles himself. The First Lord of the Admiralty, Hugh Childers, and Under-Secretary of State for War, Thomas Baring, both lost sons in the disaster. Only 18 of the crew survived by making it to a boat which had broken free.
The subsequent investigation, under Sir James Hope, took place on board HMS Duke of Wellington, in Portsmouth Harbour. It was somewhat of a departure for the Admiralty to seek scientific advice but eminent engineers William Thomson (later Lord Kelvin) and William John Macquorn Rankine were appointed to the enquiry. It concluded that the ship was insufficiently stable: at 14 degrees heel (when the edge of the deck touched the sea) the Righting Moment (torque) due to the buoyancy pushing the ship upright again was just 410 foot-tons (1.2MNm). HMS Monarch, the masted turret ship proposed by the 1865 committee and designed by Reed, and which was also at sea at the time of the sinking, had a righting moment of 6,500 foot-tons (20MNm) at the same angle.[10] Maximum righting moment occurred at a heel of 21 degrees, and thereafter declined to zero at 54.5 degrees. Monarch's righting moment increased to a maximum at 40 degrees.[11]
The inquiry concluded that "the Captain was built in deference to public opinion expressed in Parliament and through other channels, and in opposition to views and opinions of the Controller and his Department".[12]
