Dhow with lateen sail in "bad tack" with the sail pressing against the mast, in Mozambique.. The emergence of new evidence for the development and spread of the lateen sail in the ancient Mediterranean in recent decades has led to a reevaluation of the role of Arab seafaring in the Indian Ocean, replacing a belief that this sail has an eastern origin.
Lateen sails were such an innovation because they had the ability to carry a ship with even the smallest of breezes. [4] Atlantic sailors tended to utilize a stouter, heavier Baltic cog, lapstrake, planked cargo ship with a single square sail that had axial stern rudders that was meant to help in the stormy waters they were accustomed to.
The caravel (Portuguese: caravela, IPA: [kɐɾɐˈvɛlɐ]) is a small sailing ship that may be rigged with just lateen sails, or with a combination of lateen and square sails. It was known for its agility and speed and its capacity for sailing windward ( beating ).
Result of the natural evolution of new requirements raised by war, soon they were built with four masts; the larger vessels had this configuration, always with lateen rigged sails in the two mizzen-masts in almost all galleons, and a third square smaller sail at the tops of the fore-mast and the main-mast (the latter in larger ships), which can ...
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 ...
Instead, the lowest sail on the mizzen was usually a fore/aft sail—originally a lateen sail, but later a gaff sail called a spanker or driver. The key distinction between a ship and a barque (in modern usage) is that a ship carries a square-rigged mizzen topsail (and therefore that its mizzen mast has a topsail yard and a cross-jack yard ...
Advances in shipbuilding included the multi-masted ships with lateen sails, the sternpost-mounted rudder and the skeleton-first hull construction. Along with new navigational techniques such as the dry compass , the Jacob's staff and the astrolabe , these allowed economic and military control of the seas adjacent to Europe and enabled the ...
[a] Since mat sails are not as strong as other sail materials, such as canvas, it is important that the spars provide the necessary reinforcement of the edges. [ 15 ] : 248 The crab claw may also traditionally be constructed with curved spars, giving the edges of the sail along the spars a convex shape, while the leech of the sail is often ...
