Jury Rigging
In maritime transport and sailing, jury rigging or jury-rigging is making temporary makeshift running repairs with only the tools and materials on board. It originates from sail-powered boats and ships. Jury-rigging can be applied to any part of a ship; be it its super-structure ( hull, decks), propulsion systems ( mast, sails, rigging, engine, transmission, propeller), or controls ( helm, rudder, centreboard, daggerboards, rigging). Similarly, a jury mast is a replacement mast after a dismasting. If necessary, a yard would also be fashioned and stayed to allow a watercraft to resume making way. Rigging A sail-powered boat may carry a limited amount of repair materials, from which some form of jury-rig can be fashioned. Additionally, anything salvageable, such as a spar or spinnaker pole, could be adapted to carry a makeshift sail. Ships typically carried a selection of spare parts such as topmasts. However, due to their much larger size, at up to in diameter, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or afterend. Often rudders are shaped to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics. H ...

Ship
A ship is a large watercraft, vessel that travels the world's oceans and other Waterway, navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported Geographic exploration, exploration, Global trade, trade, Naval warfare, warfare, Human migration, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a Full-rigged ship, ship-rigged sailing ship with three or more masts, each of which is Square rig, square-rigged. The earliest historical evidence of boats is found in Egypt during the 4th millennium BCE. In 2024, ships had a global cargo capacity of 2.4 billion tons, with the three largest classes being ships carrying dry bulk (43%), ...

Spinnaker Pole
A spinnaker pole is a spar used in sailboats (both dinghies and yachts) to help support and control a variety of headsails, particularly the spinnaker. It is also used with other sails, such as genoas and jibs, when sailing downwind with no spinnaker hoisted, sometimes using a special light spinnaker pole called a whisker pole, possible since the load on the pole is very light on this point of sail. Rigging The spinnaker pole is rigged to run from the base of the mast, where there is a special fitting for attaching one end of the pole, out to windward over the side of the boat. There, one of the control lines of whichever sail it is to be used with is run through a fitting on the other end of the spinnaker pole. This allows for more precise control of the corner of the sail to which the line is attached. For a spinnaker, the line attached to the pole is the guy, or brace, and the corner is the tack. For other headsails, such as a jib, the line would be the sheet, atta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spar (sailing)
A spar is a pole of wood, metal or lightweight materials such as carbon fibre used in the rigging of a sailing vessel to carry or support its sail. These include yards, booms, and masts, which serve both to deploy sail and resist compressive and bending forces, as well as the bowsprit and spinnaker pole. In larger vessels during the age of sail, spare spars could be roped together to provide a temporary surface known as a "spar deck". These served as jury-rigged repairs for permanent decks, or as an additional platform under which to shelter goods or crew. The term was also informally applied to areas of the forecastle The forecastle ( ; contracted as fo'c'sle or fo'c's'le) is the upper deck (ship), deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters. Related to the latter meaning is t ... or quarterdeck where spare spars were stored by laying them flat against the existing decking. In the moder ...

Sailboat
A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture. Types Although sailboat terminology has varied across history, many terms have specific meanings in the context of modern yachting. A great number of sailboat-types may be distinguished by size, hull configuration, keel type, purpose, number and configuration of masts, and sail plan. Popular monohull designs include: Cutter The cutter is similar to a sloop with a single mast and mainsail, but generally carries the mast further aft to allow for two foresails, a jib and staysail, to be attached to the head stay and inner forestay, respectively. Once a common racing configuration, today it gives versatility to cruising boats, especially in allowing a small staysail to be flown from the inner stay in high winds. Catboat A catboat has a single mast mounted far forw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Way (vessel)
Way or WAY may refer to: Paths * a road, route, trail, path or pathway, including long-distance paths * a straight rail or track on a machine tool (such as that on the bed of a lathe) on which part of the machine slides * Ways, large slipway in shipbuilding, the ramps down which a ship is pushed in order to be launched * Way (vessel), a ship's speed or momentum Religion * "The Way", New Testament term for Christianity * Way of the Cross, Christian devotion that commemorates the events of Good Friday following 14 stations, taking the form of a spiritual pilgrimage through contemplation and meditation of the Passion of Christ * Tao (Chinese: "The Way" 道), a philosophical concept (cf.

Stays (nautical)
Stays are ropes, wires, or rods on sailing Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the ''water'' (sailing ship, sailboat, raft, Windsurfing, windsurfer, or Kitesurfing, kitesurfer), on ''ice'' (iceboat) or on ''land'' (Land sa ... vessels that run fore-and-aft along the centerline from the masts to the hull, deck, bowsprit, or to other masts which serve to stabilize the masts. A stay is part of the standing rigging and is used to hold a mast upright. It is a large strong rope, wire or rod extending from the upper end of each mast and running down towards the deck of the vessel in a midships -and- direction. The shrouds serve a similar function but extend on each side of the mast and provide support in the athwartships direction. The object of both is to prevent the masts from falling down but the stays also prevent springing, when the ship is pitching deep. Thus stays are fore and aft. Those led aft ...

Yard (sailing)
A yard is a spar (sailing), spar on a mast (sailing), 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 (sailing), 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 aro ...

Clarendon Press
Oxford University Press (OUP) is the publishing house of the University of Oxford. It is the largest university press in the world. Its first book was printed in Oxford in 1478, with the Press officially granted the legal right to print books by decree in 1586. It is the second-oldest university press after Cambridge University Press, which was founded in 1534. It is a department of the University of Oxford. It is governed by a group of 15 academics, the Delegates of the Press, appointed by the vice-chancellor of the University of Oxford. The Delegates of the Press are led by the Secretary to the Delegates, who serves as OUP's chief executive and as its major representative on other university bodies. Oxford University Press has had a similar governance structure since the 17th century. The press is located on Walton Street, Oxford, opposite Somerville College, in the inner suburb of Jericho. For the last 400 years, OUP has focused primarily on the publication of pedagogic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dismasting
Dismasting, also called demasting, occurs to a sailing ship when one or more of the mast (sailing), masts responsible for hoisting the sails that propel the vessel breaks. Dismasting usually occurs as the result of high winds during a storm acting upon masts, sails, rigging, and spar (sailing), spars. Over-compression (physics), compression of the mast due to the rigger being over-tightened, as well as g-forces caused by wave action and the boat swinging back and forth, can also result in a dismasting. Dismasting does not necessarily impair the vessel's ability to stay afloat, but rather its ability to move under sail power. Frequently, the hull (watercraft), hull of the vessel remains intact, upright and seaworthy. Modern masts are usually made of aluminum, carbon fibre, or other high-strength materials. These masts are subject to huge forces and tensions during high wind, large seas, or racing situations, and it is not uncommon even today for modern masts to be lost. Factors ...
