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.

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 ...

Crab Claw Sail
The crab claw sail is a fore-and-aft triangular sail with spars along upper and lower edges. The crab claw sail was first developed by the Austronesian peoples some time around 1500 BC. It is used in many traditional Austronesian cultures in Island Southeast Asia, Micronesia, Island Melanesia, Polynesia, and Madagascar. Due to its extraordinary performance and ease of operation, it has also become very popular in modern sport sailing. It is sometimes known as the Oceanic lateen or the Oceanic sprit, even though it is not restricted to Oceania, is neither a lateen sail nor a spritsail, and has an independent older origin. History Crab-claw sails were invented by the Austronesians somewhere in Island Southeast Asia at no later than 1500 BCE. It was derived from a more ancient mast-less V-shaped square rig consisting simply of a square or triangular sail on two spars perpendicular to the hull converging at the base. It spread with the Austronesian migration to Micronesia, Island Mel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galley
A galley is a type of ship that is propelled mainly by oars. The galley is characterized by its long, slender hull, shallow draft, and low freeboard (clearance between sea and gunwale). Virtually all types of galleys had sails that could be used in favorable winds, but human effort was always the primary method of propulsion. This allowed galleys to navigate independently of winds and currents. The galley originated among the seafaring civilizations around the Mediterranean Sea in the late second millennium BC and remained in use in various forms until the early 19th century in warfare, trade, and piracy. Galleys were the warships used by the early Mediterranean naval powers, including the Greeks, Illyrians, Phoenicians, and Romans. They remained the dominant types of vessels used for war and piracy in the Mediterranean Sea until the last decades of the 16th century. As warships, galleys carried various types of weapons throughout their long existence, including rams, cata ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dromon
A dromon (from Greek δρόμων, ''dromōn'', "runner") was a type of galley and the most important warship of the Byzantine navy from the 5th to 12th centuries AD, when they were succeeded by Italian-style galleys. It was developed from the ancient liburnian, which was the mainstay of the Roman navy during the Empire. Middle English ''dromond'' and Old French ''dromont'' are derived from the dromon, and described any particularly large medieval ship. Evolution and features The appearance and evolution of medieval warships is a matter of debate and conjecture; until recently, no remains of an oared warship from either ancient or early medieval times had been found and information had to be gathered by analyzing literary evidence, crude artistic depictions and the remains of a few merchant vessels (such as the 7th-century Pantano Longarini wreck from Sicily, the 7th-century Yassi Ada ship and the 11th-century Serçe Limanı wreck).

Mast (sailing)
The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed. Until the mid-19th century, all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a conifer tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than could be made from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts). From lowest to highest, these were called: lower, top, topgallant, and royal masts. Givin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Settee (sail)
The settee sail was a lateen sail with the front corner cut off, giving it a quadrilateral shape. It can be traced back to Greco-Roman navigation in the Mediterranean in late antiquity; the oldest evidence is from a late-5th-century AD ship mosaic at Kelenderis, Cilicia. It lasted well into the 20th century as a common sail on Arab dhows. The settee sail requires a shorter yard than does the lateen, and both settee and lateen have shorter masts than square-rigged sails. Model of a sambuk with two settee sails Settees (or ''saëtia'') then were a sharp-prowed, single-decked merchant sailing vessel found in the Mediterranean (more in the Levant than in the Western Mediterranean), in the 18th and 19th centuries. The Spaniards also used them in the New World. Settees had two lateen-rigged masts, like xebecs or galleys, but carrying settee sails. They sailed well to windward and could sail downwind. Some polaccas carried a settee sail, giving rise to the polacca-settee (or polacre-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fore-and-aft
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ves ...

Full-rigged Ship
A full-rigged ship or fully rigged ship is a sailing vessel's sail plan with three or more masts, all of them square-rigged. A full-rigged ship is said to have a ship rig or be ship-rigged. Such vessels also have each mast stepped in three segments: lower mast, top mast, and topgallant mast. Other large, multi-masted sailing vessels may be regarded as ships while lacking one of the elements of a full-rigged ship, e.g. having one or more masts support only a fore-and-aft sail or having a mast that only has two segments. Masts The masts of a full-rigged ship, from bow to stern, are: * Foremast, which is the second tallest mast * Mainmast, the tallest * Mizzenmast, the third tallest * Jiggermast, which may not be present but will be fourth tallest if so If the masts are of wood, each mast is in three or more pieces. They are (in order, from bottom up): * The lowest piece is called the ''mast'' or the ''lower''. * Topmast * Topgallant mast * Royal mast, if fitted On steel- ...
