COURSES, pacfis, a name by which the principal sails of a ship are usually distinguished, viz. the main-sail, fore-sail, and mizen: the mizen-stay-sail and fore-sail are also sometimes comprehended in this denomination, as are the main-stay-sails of all brigs and schooners. See the article Sail.

CRAB, a sort of wooden pillar, whose lower end, being let down through a ship’s decks, rests upon a socket like the capstern; and having in its upper-end three or four holes, at different heights, thro’ the middle of it, above one another, into which long bars are thrust, whose length is nearly equal to the breadth of the deck. It is employed to wind in the cable, or to purchase any other weighty matter which requires a great mechanical power. This differs from a capstern, as not being furnished with a drum-head, and by having the bars to go intirely through it, reaching from one side of the deck to the other; whereas those of the capstern, which are superior in number, reach only about eight inches or a foot into the drum-head, according to the size thereof. This machine is represented in plate [II]. by fig. 10, and 13. See also Capstern.

CRADLE, slee, a frame placed under the bottom of a ship, in order to conduct her smoothly and steddily into the water when she is to be lanched; at which time it supports her weight whilst she slides down the descent, or sloping passage called the ways, which are for this purpose daubed with soap and tallow. This frame is exhibited by fig. 23, plate [II].

CRAFT, a general name for all sorts of vessels employed to load or discharge merchant-ships, or to carry along-side, or return the stores of men of war: such are lighters, hoys, barges, prames, &c. See those articles.

CRANK, coté-foible, the quality of a ship, which for want of a sufficient quantity of ballast or cargo, is rendered incapable of carrying sail without being exposed to the danger of overturning. See the articles Ballast and Trim.

Crank, is also an iron brace which supports the lanthorns on the poop-quarters, &c.

CRAWL, bouchot, a sort of pen, or place of confinement, formed by a barrier of stakes and hurdles on the sea-coast, to contain any sort of fish within it.

CREEPER, an instrument of iron resembling a grappling, having a shank and four hooks or claws, fig. 24, plate [II]. It is used to throw into the bottom of any river or harbour, with a rope fastened to it, to hook and draw up any thing from the bottom which may have been lost.

CRINGLE, ancet, a small hole made in the bolt-rope of a sail, by inter-twisting one of the divisions of a rope, called a strand, alternately round itself and through the strands of the bolt-rope, till it becomes three-fold, and assumes the shape of a wreath or ring. See plate [II]. fig. 25, where a, b, represents part of the bolt-rope of a sail; and c, the cringle.

The use of the cringle is generally to contain the end of some rope, which is fastened thereto, for the purpose of drawing up the sail to its yard, or of extending the skirts by the means of bridles to stand upon a side-wind. The word seems to be derived from krinckelen, (Belg.) to run into twists.
