Rigging comprises the system of ropes, cables and chains, which support and control a sailing ship or sail boat's masts and sails. ''Standing rigging'' is the fixed rigging that supports masts including shrouds and stays. ''Running rigging'' is rigging which adjusts the position of the vessel's sails and spars including halyards, braces, sheets and vangs. Etymology According to the Encyclopædia Britannica Eleventh Edition "rigging" derives from Anglo-Saxon ''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. History Theophrastus in his '' History of Plants'' ( 300 BCE) states that the rigging on King Antigonus' fleet was made from papyrus reed. Types of rigging Rigging is divided into two classes, ''standing'', which supports the mast (and bowsprit), and ''running'', which controls the orientation ...

Antigonus I Monophthalmus
Antigonus I Monophthalmus ( , "Antigonus the One-Eyed"; 382 – 301 BC) was a Ancient Macedonians, Macedonian Greek general and Diadochi, successor of Alexander the Great. A prominent military leader in Alexander's army, he went on to control large parts of Empire of Alexander the Great, Alexander's former empire. He assumed the title of ''basileus'' (king) in 306 BC and reigned until his death. He was the founder of the Antigonid dynasty, which ruled over Macedonia until its conquest by the Roman Republic in 168 BC. Antigonus likely served under Philip II of Macedon. He took part in Alexander's Wars of Alexander the Great, invasion of Achaemenid Persia and was named satrap of Phrygia. After Alexander's death in 323 BC, he also received Pamphylia and Lycia in accordance with the Partition of Babylon. However, he later incurred the enmity of Perdiccas, the regent of Alexander's empire, and was driven from Phrygia. He fled to Greece and formed an alliance with Antipater, later joine ...

Deadeye
A deadeye is an item used in the standing and running rigging of traditional sailing ships. It is a smallish round thick wooden (usually lignum vitae) disc with one or more holes through it, perpendicular to the plane of the disc. Single and triple-hole deadeyes are most commonly seen. The three-holed blocks were called deadeyes because the position of the three holes resemble the eye and nose sockets of a sheep's skull. Single deadeyes (or bull's eyes) are used to guide and control a line and, particularly in older vessels, to change its direction. More modern systems would use a block for this purpose but in traditional rigs with many lines to deal with, designed when blocks were relatively expensive to make, a deadeye provided an acceptable compromise. When blocks came into common use for adjusting running rigging, deadeyes continued to be used for tensioning standing rigging. Triple deadeyes are used in pairs; a line called a lanyard is run back and forth between them, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swage Terminal
A swage terminal is a product used to terminate wire. A swaging machine is used to terminate the wire. The wire is passed into a deep hole in the swage terminal which is then pressed onto the terminal by applying force. This type of product is used in the architectural and marine industries. There are many companies globally who manufacture swage terminals, including Sta-Lok. See also *Swage Swaging () is a forging process in which the dimensions of an item are altered using dies into which the item is forced. Swaging is usually a cold working process, but also may be hot worked. The term swage may apply to the process (verb) o ... * Swageless terminal Structural connectors {{Tool-stub ...

Swageless Terminal
In 1973 Sta-Lok launched the swageless terminal system for wire rope at the London Boat Show. The swageless terminal can be fitted by using hand tools, unlike a swage terminal which requires a special press, roller die or rotary hammer machine to crimp it onto a wire. This makes them very useful if the wire assembly must be made-up on site. A swageless terminal will work under constant loading and variable shock loading, making it stronger than the wire rope. Regardless of manufacturer the basic principle of operation is the same. The cable has its outer layers wrapped around a metal cone, with the rope's core running through a hole in the middle of the cone. The assembly sits inside a conical outer body. When the cable is in tension, the action is such that the cone and wire are drawn further into the conical bore of the outer body resulting in a large reaction load. This load grips the wire and prevents further movement. As with swage terminals, swageless terminals ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backstay
A backstay is a piece of standing rigging on a sailing vessel that runs from the mast to either its transom or rear quarter, counteracting the forestay and jib. It is an important sail trim control and has a direct effect on the shape of the mainsail and the headsail. Backstays are generally adjusted by block and tackle, hydraulic adjusters, or lines leading to winches. Types Backstays may be ''permanent'' or ''running''. Permanent backstay A permanent backstay is attached to the top of the mast. Running backstays appear in pairs attached about two-thirds of the way up the mast (sometimes at multiple locations along the length of the mast). In general, most modern sailboats have a permanent backstay and some have a permanent backstay combined with running backstays. Backstays are not always found on all vessels, especially smaller ones. A permanent backstay is attached at the top of the mast and may or may not be readily adjustable. In a masthead rig, tensioning the perma ...

Forestay
On a sailing vessel, a forestay, sometimes just called a stay, is a piece of standing rigging which keeps a mast from falling backwards. It is attached either at the very top of the mast, or in fractional rigs between about 1/8 and 1/4 from the top of the mast. The other end of the forestay is attached to the bow of the boat. Often a sail is attached to the forestay. This sail may be a jib or a genoa. In a cutter rig, the jib or jibs are flown from stays in front of the forestay, perhaps going from the masthead to a bowsprit. The sail on the forestay is then referred to as the staysail or stays'l. A forestay might be made from stainless steel wire on a modern yacht, solid stainless steel rod, carbon rod, or ultra high molecular weight polyethylene (such as Spectra or Dyneema) on a high-performance racing boat, and galvanised wire or natural fibers on an older cutter or square-rigged ship.

Tension (physics)
Tension is the pulling or stretching force transmitted axially along an object such as a string, rope, chain, rod, truss member, or other object, so as to stretch or pull apart the object. In terms of force, it is the opposite of ''compression''. Tension might also be described as the action-reaction pair of forces acting at each end of an object. At the atomic level, when atoms or molecules are pulled apart from each other and gain potential energy with a restoring force still existing, the restoring force might create what is also called tension. Each end of a string or rod under such tension could pull on the object it is attached to, in order to restore the string/rod to its relaxed length. Tension (as a transmitted force, as an action-reaction pair of forces, or as a restoring force) is measured in newtons in the International System of Units (or pounds-force in Imperial units). The ends of a string or other object transmitting tension will exert forces on the objects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deck (ship)
A deck is a permanent covering over a Compartment (ship), compartment or a hull (watercraft), hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-storey building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure. Decks for some purposes have specific names. Structure The main purpose of the upper or primary deck is structural, and only secondarily to provide weather-tightness and support people and equipment. The deck serves as the lid to the complex box girder which can be identified as the hull. It resists Tension (physics), tension, Compression (physics), compression, and racking forces. The deck's scantling is usually the same as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standing Rigging
Standing rigging comprises the fixed lines, wires, or rods, which support each mast or bowsprit on a sailing vessel and reinforce those spars against wind loads transferred from the sails. This term is used in contrast to running rigging, which represents the moveable elements of rigging which adjust the position and shape of the sails. Historical development Early sailing vessels used rope of hemp or other fibers, which gave way to wire ropes of various types. Galvanized steel was common for the first half of the 20th century, continuing as an inexpensive option to its 1960s successor material—stainless steel cables and rods. In the late 20th Century, racing yachts adopted composite fiber lines for standing rigging, with the goal of reducing weight and windage aloft. Materials On modern yachts, standing rigging is often stainless steel wire, Nitronic-50 stainless steel rod or synthetic fiber Synthetic fibers or synthetic fibres (in British English; see spelling ...

Square-rig
Square rig is a generic type of sail and rigging arrangement in which a sailing vessel's primary driving sails are carried on horizontal spars that are perpendicular (or square) to the median plane of the keel and masts of the vessel. These spars are called and their tips, outside the lifts, are called the . A ship mainly rigged so is called a square-rigger. In " Jackspeak" (Royal Navy slang), it also refers to the dress uniform of Junior Ratings. History 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 becoming one of the defining characteristics of the classic “Viking” ships.The Viking ship's single square-rigged sail. http://Longshipco.org/sail.html Retrieved 2018-8-20 See also * Glossary of nautical terms (A-L) Glossary of nautical terms may refer to: * Glossary of nautical terms (A–L) ...

Fore-and-aft Rig
A fore-and-aft rig is a sailing ship rig with sails set mainly in the median plane of the keel, rather than perpendicular to it, as on a square-rigged vessel. Description Fore-and-aft rigged sails include staysails, Bermuda rigged sails, gaff rigged sails, gunter rig, lateen sails, lug sails, tanja sails, the spanker sail on a square rig, and crab claw sails. Fore-and-aft rigs include: * Rigs with one mast: the proa, the catboat, the sloop, the cutter * Rigs with two masts: the ketch, the yawl * Rigs with two or more masts: the schooner Barques and barquentines are partially square rigged and partially fore-and-aft rigged. A rig which combines both on a foremast is known as a hermaphroditic rig. History Austronesia The fore-and-aft rig is believed to have been developed independently by the Austronesian peoples some time after 1500 BC with the invention of the crab claw sail. It is suggested that it evolved from a more primitive V-shaped "square" sail wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
