Sail Plan
A sail plan is a description of the specific ways that a sailing craft is rigged. Also, the term "sail plan" is a graphic depiction of the arrangement of the sails for a given sailing craft.> In the English language, ships were usually described, until the end of the eighteenth century, in terms of their type of hull design. Using the type of rig as the main type identifer for a vessel only became common in the nineteenth century. This is illustrated by the terminology for ships in the large fleet of colliers that traded to London from the coal ports of the Northeast of England (of which was a well-known example). Many of these full-rigged ships (square rigged on all of three masts) had the hull type "bark"another common classification was "cat". In the second half of the eighteenth century, the square sails on the mizzen were often eliminated. The resulting rig acquired the name of the hull type: initially as "bark" and soon as "barque". This explains the Royal Navy's descripti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lateen Rig
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. It has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

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 or quarterdeck where spare spars were stored by laying them flat against the existing decking. In the modern era the term has been used to describe the uppermost deck on flush deck Flush deck is a term in naval architecture. It can refer to any deck of a ship which is continuous from stem to stern. History The flush deck design originated with rice ships built ...

Fore And Aft Sails
A fore-and-aft rig is a sailing vessel rigged mainly with sails set along the line 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, gaff 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 first developed independently by the Austronesian peoples some time around 1500 BC with the invention of the crab claw sail. It is suggested that it evolved from a more primitive "V"-shaped "square" s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thames Barges-Canthusus
The River Thames ( ), known alternatively in parts as the River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire, and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west it flows through Oxford (where it is sometimes called the Isis), Reading, Henley-on-Thames and Windsor. The Thames also drains the whole of Greater London. In August 2022, the source of the river moved five miles to beyond Somerford Keynes due to the heatwave in July 2022. The lower reaches of the river are called the Tideway, derived from its long tidal reach up to Teddington Lock. Its tidal section includes most of its London stretch and has a rise and fall of . From Oxford to the Estuary the Thames drops by 55 metres. Running through some of the drier parts of mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DynaRig
The DynaRig is a conceptualization of a square-rigged form of rigging, designed in the 1960s by the German engineer Wilhelm Prölß. While having the appearance of the rigging of a 19th-century clipper ship, it was not actually implemented on a sailing vessel until several decades after its design because of a lack of adequate construction materials. It was fitted to one of the world's largest yachts, the '' Maltese Falcon''. When the original patent rights and residual technology were purchased from the German government by an American investor in 2001, it was renamed the Falcon rig. The DynaRig, along with the original, "DynaSchiff", is a trademarked name. The original concept by Prölß was for a combined rig and hull with extremely high efficiency of operation and the use of wind power to propel a large vessel across an open body of water. The modern controller for the entire ship's rig consists of a single panel operated by a single person. The masts are freestanding, the curv ...

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] |
Rigging
Rigging comprises the system of ropes, cables and chains, which support a sailing ship or sail boat's masts—''standing rigging'', including shrouds and stays—and which adjust the position of the vessel's sails and spars to which they are attached—the ''running rigging'', 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. 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 ''fore-and-aft rigged'' vessels and ''square-rigged'' vessels. Standing Standin ...

Yard (sailing)
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 vess ...

Tanja Sail
Tanja sail (Malay language, Malay: ''layar tanjak'') or tanja rig is a type of sail commonly used by the Austronesian peoples, Austronesian people, particularly in Maritime Southeast Asia. It is also known as the tilted square sail, canted rectangular sail, rectangular balance lug, or Lug sail#Types, balance lug sail in English.Needham, Joseph (1971). ''Science and Civilisation in China: Volume 4, Physics and Physical Technology, Part III: Civil Engineering and Nautics''. Cambridge: Cambridge University Press. In historical sources, tanja sail is sometimes incorrectly referred to as Lateen Sail, lateen sail or simply square sail. Etymology Also called tanjaq, tanjak, tanja', tanjong, or tanjung sail. The Mandar people call it ''sombal tanjaq'' because when the wind blows the lower part of the sail (''peloang'') would "''mattanjaq''" (lit. "kick"). In colonial British records, it is sometimes written as "lyre ''tanjong''", a misspelling of ''layar tanjong'' (''layar'' means "sail" ...
