''wrigan'' or ''wringing'', "to clothe". The same source points out that "rigging" a sailing vessel refers to putting all the components in place to allow it to function, including the masts, spars, sails and the rigging.


Types of rigging

Rigging is divided into two classes, '' standing'', which supports the mast (and bowsprit), and ''running'', which controls the orientation of the sails and their degree of reefing. Configurations differ for each type of rigging, between ''

Standing

Standing rigging is cordage which is fixed in position. Standing rigging is almost always between a mast and the deck, using tension to hold the mast firmly in place. Due to its role, standing rigging is now most commonly made of steel cable. It was historically made of the same materials as running rigging, only coated in tar for added strength and protection from the elements.


Fore-and-aft rigged vessels

Most fore-and-aft rigged vessels have the following types of standing rigging: a forestay, a backstay, and upper and lower
shrouds Shroud usually refers to an item, such as a cloth, that covers or protects some other object. The term is most often used in reference to ''burial sheets'', mound shroud, grave clothes, winding-cloths or winding-sheets, such as the famous Shr ...
(side stays). Less common rigging configurations are diamond stays and jumpers. Both of these are used to keep a thin mast in column especially under the load of a large down wind sail or in strong wind. Rigging parts include swageless terminals,

Square-rigged vessels

Whereas 20th-century square-rigged vessels were constructed of steel with steel standing rigging, prior vessels used wood masts with hemp-fiber standing rigging. As rigs became taller by the end of the 19th century, masts relied more heavily on successive spars, stepped one atop the other to form the whole, from bottom to top: the ''lower mast'', ''top mast'', and ''topgallant mast''. This construction relies heavily on support by a complex array of stays and shrouds. Each stay in either the fore-and-aft or athwartships direction has a corresponding one in the opposite direction providing counter-tension. Fore-and-aft the system of tensioning start with the stays that are anchored in front of each mast. Shrouds are tensioned by pairs of deadeyes, circular blocks that have the large-diameter line run around them, whilst multiple holes allow smaller line—''lanyards''—to pass multiple times between the two and thereby allow tensioning of the shroud. In addition to overlapping the mast below, the top mast and topgallant mast are supported laterally by shrouds that pass around either a platform, called a " top", or cross-wise beams, called "
crosstrees Crosstrees are the two horizontal spars at the upper ends of the topmasts of sailing ships, used to anchor the shrouds from the topgallant mast. Similarly, they may be mounted at the upper end of the topgallant to anchor the shrouds from the r ...
". Each additional mast segment is supported fore and aft by a series of stays that lead forward. These lines are countered in tension by backstays, which are secured along the sides of the vessel behind the shrouds.


Running

Running rigging is the cordage used to control the shape and position of the sails. Materials have evolved from the use of Manilla rope to synthetic fibers, which include

and kevlar. Running rigging varies between ''fore-and-aft rigged'' vessels and ''square-rigged'' vessels. They have common functions between them for supporting, shaping and orienting sails, which employ different mechanisms. For supporting sails, halyards (sometimes haulyards), are used to raise sails and control luff tension. On
