CAPSTAN-SWIFTER. A rope passed horizontally through notches in the outer ends of the bars, and drawn very tight: the intent is to steady the men as they walk round when the ship rolls, and to give room for a greater number to assist, by manning the swifters both within and without. CAPTAIN. This title is said to be derived from the eastern military magistrate _katapan_, meaning "over everything;" but the term _capitano_ was in use among the Italians nearly 200 years before Basilius II. appointed his katapan of Apulia and Calabria, A.D. 984. Hence, the corruption of the Apulian province into _capitanata_. Among the Anglo-Saxons the captain was _schipp-hláford_, or ship's lord. The captain, strictly speaking, is the officer commanding a line-of-battle ship, or a frigate carrying twenty or more cannon. A captain in the royal navy is answerable for any bad conduct in the military government, navigation, and equipment of his ship; also for any neglect of duty in his inferior officers, whose several charges he is appointed to regulate. It is also a title, though incorrectly, given to the masters of all vessels whatever, they having no commissions. It is also applied in the navy itself to the chief sailor of particular gangs of men; in rank, captain of the forecastle, admiral's coxswain, captain's coxswain, captain of the hold, captain of main-top, captain of fore-top, &c. CAPTAIN. A name given to the crooner, crowner, or gray gurnard (_Trigla gurnardus_). CAPTAIN OF A MERCHANT SHIP. Is a certificated officer in the mercantile marine, intrusted with the entire charge of a ship, both as regards life and property. He is in no way invested with special powers to meet his peculiar circumstances, but has chiefly to depend upon moral influence for maintaining order amongst his passengers and crew during the many weeks or even months that he is cut off from appeal to the laws of his country, only resorting to force on extreme occasions. Great tact and judgment is required to fulfil this duty properly. CAPTAIN OF A SHIP OF WAR. Is the commanding officer; as well the post-captain (a title now disused) as those whose proper title is commander. CAPTAIN OF THE FLEET. Is a temporary admiralty appointment; he is entitled to be considered as a flag-officer, and to a share in the prize-money accordingly. He carries out all orders issued by the commander-in-chief, but his special duty is to keep up the discipline of the fleet, in which he is supreme. He is the adjutant-general of the force, hoisting the flag and wearing the uniform of rear-admiral. CAPTAIN OF THE HEAD. Not a recognized rating, but an ordinary man appointed to attend to the swabs, and to keep the ship's head clean. CAPTAIN OF THE HOLD. The last of the captains in rank, as a first-class petty officer.
