Yardarms
A yard is a spar on a mast from which sails are set. It may be constructed of timber or steel or from more modern materials such as aluminium or carbon fibre. Although some types of fore and aft rigs have yards, the term is usually used to describe the horizontal spars used on square rigged sails. In addition, for some decades after square sails were generally dispensed with, some yards were retained for deploying wireless (radio) aerials and signal flags. Parts of the yard ; Bunt : The short section of the yard between the ''slings'' that attach it to the mast. ; Quarters : The port and starboard quarters form the bulk of the yard, extending from the slings to the fittings for the lifts and braces. ; Yardarms : The outermost tips of the yard: outboard from the attachments for the lifts. Note that these terms refer to stretches of the same spar, not to separate component parts. Controlling the yard The yard can rotate around the mast to allow the direction of the vesse ...

Sail
A sail is a tensile structure—which is made from fabric or other membrane materials—that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or bonded filaments—usually in a three- or four-sided shape. A sail provides propulsive force via a combination of lift and drag, depending on its angle of attack—its angle with respect to the apparent wind. Apparent wind is the air velocity experienced on the moving craft and is the combined effect of the true wind velocity with the velocity of the sailing craft. Angle of attack is often constrained by the sailing craft's orientation to the wind or point of sail. On points of sail where it is possible to align the leading edge of the sail with the apparent wind, the sail may act as an airfoil, generating propulsive force as air p ...

Square-rig
Square rig is a generic type of sail and rigging arrangement in which the primary driving sails are carried on horizontal spars which are perpendicular, or square, to the keel of the vessel and to the masts. These spars are called ''yards'' and their tips, outside the lifts, are called the ''yardarms.'' A ship mainly rigged so is called a square-rigger. The square rig is aerodynamically the most efficient running rig (i.e., sailing downwind), and stayed popular on ocean-going sailing ships until the end of the Age of Sail. The last commercial sailing ships, windjammers, were usually square-rigged four-masted barques. History The oldest archaeological evidence of use of a square-rig on a vessel is an image on a clay disk from Mesopotamia from 5000 BC. Single sail square rigs were used by the ancient Egyptians, the Phoenicians, the Greeks, the Romans, and the Celts. Later the Scandinavians, the Germanic peoples, and the Slavs adopted the single square-rigged sail, with it be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Footrope
Each yard on a square or gaff rigged sailing ship is equipped with a footrope for sailors to stand on while setting or stowing the sails. Formerly, the footrope was the rope sewn along the lower edge of a square sail, and the rope below the yards was called the horse or Flemish horse. These terms will be encountered when reading the classic 18th and 19th century sailing manuals, and may still be used today when referring to older ships. Although square sails are mostly worked from the deck, in order to be properly stowed (and released from this stowage) they must be folded by hand and tied to the yard with gaskets. This requires sailors to go aloft, during which time they stand on the footropes. The ropes are made of either fibre or wire, and are almost always protected from wear by being wormed, parcelled and served, so that the visible outer coating is of tarred thin line. They are attached to the yard via the jackstays or "handrails" to which the sails are also fastened, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lateen
A lateen (from French ''latine'', meaning "Latin") or latin-rig is a triangular sail set on a long yard mounted at an angle on the mast, and running in a fore-and-aft direction. The settee can be considered to be an associated type of the same overall category of sail. The lateen originated in the Mediterranean as early as the 2nd century CE, during Roman times, and became common there by the 5th century. The wider introduction of lateen rig at this time coincided with a reduction in the use of the Mediterranean square rig of the classical era. Since the performance of these two rigs is broadly similar, it is suggested that the change from one to the other was on cost grounds, since lateen used fewer components and had less cordage to be replaced when it wore out. Arab seafarers adopted the lateen rig at a later datethere is some limited archaeological evidence of lateen rig in the Indian Ocean in the 13th century CE and iconographic evidence from the 16th century.

Cutty Sark Tall Ships' Race
The Tall Ships Races are races for sail training "tall ships" (sailing ships). The races are designed to encourage international friendship and training for young people in the art of sailing. The races are held annually in European waters and consists of two racing legs of several hundred nautical miles, and a "cruise in company" between the legs. Over one half of the crew of each ship participating in the races must consist of young people. Between 1973 and 2003 the races were known as The Cutty Sark Tall Ships Races, having been sponsored by Cutty Sark whisky. From 2004 to 2010 the races were supported by the City, Province and Port of Antwerp. The sponsor of the Tall Ships Races 2010–2014 was the city of Szczecin. Tall ships By the 21st century, "tall ship" is often used generically for large, classic, sailing vessels, but is also a technically defined term by Sail Training International. The definitions are subject to various technicalities, but by 2011 there are only t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gasket (sailing)
In sailing, gaskets are lengths of rope or fabric used for reefing a sail, or hold a stowed sail in place. In modern use, the term is usually restricted to square-rigged ships, the equivalent items on yachts being referred to by the more prosaic "sail ties". On most ships, gaskets are made of rope. They are attached to the top of the yard and, left loose, would hang behind the sail. Gaskets should never be left dangling, however, so when the sail is set they are brought around underneath the yard and up the back of it and then tied to the jackstay (metal rod) where they originated. Alternatively, longer gaskets - particularly the clew gaskets described below - can be secured using a gasket coil. When the sail is to be stowed it is first folded and bagged neatly within itself, pulled onto the top of the yard, and then the gaskets are brought round over it and secured to the jackstay to hold it in place. Gaskets should be tied with a slippery hitch to enable them to be let off quickl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheet (sailing)
In sailing, a sheet is a line (rope, cable or chain) used to control the movable corner(s) (clews) of a sail. Terminology In nautical usage the term "sheet" is applied to a line or chain attached to the lower corners of a sail for the purpose of extension or change of direction. The connection in derivation with the root "shoot" is more clearly seen in "sheet-anchor", one that is kept in reserve, to be "shot" in case of emergency. Fore-and-aft rigs Fore-and-aft rigs comprise the vast majority of sailing vessels in use today, including effectively all dinghies and yachts. The sheet on a fore-and-aft sail controls the angle of the sail to the wind, and should be adjusted to keep the sail just filled. Most smaller boats use the Bermuda rig, which has two or three sets of sheets: * The mainsheet is attached to the boom, and is used to control the mainsail. In a rig with no boom on the mainsail, the mainsheet would attach directly to the mainsail clew. A mainsheet is a line c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clewlines And Buntlines
Clewlines and buntlines are lines used to handle the sails of a square rigged ship. Although the common perception of a traditionally rigged ship is that the sails are handled from "up in the rigging", the majority of the work is actually carried out from the deck. In particular, when sailors go aloft to stow the square sails by bundling them up and tying them to the yard (with gaskets) they don't have to pull the whole weight of the sail up towards them. That work has already been carried out from the deck using the clewlines and the buntlines. As the name suggests, clewlines are attached to the outer corners or clews of the sail. They lift more weight than the buntlines, and also have to pull against the sheets - although these will have been released there is still a certain amount of friction produced by the blocks and fairleads that they run through. For this reason the clewlines are usually fitted with blocks to increase the mechanical advantage. The clewlines are colour ...
