It works by creating a difference in air pressure between the two sides (concave and convex) of the sail. This is the same way a fore-and-aft sail works. This is why the lateen sail is considered the ancestor of the fore-and-aft sail. The advantages of the lateen sail is that it is effective in lighter winds.
How do triangular sails work?
As the triangular sail inflates with a wind it creates an airfoil shape. As subsequent wind passes around the sail (airfoil), negative pressure is induced out front of and on the leeward side of the sail. This in turn causes surrounding air to rush into the sail and propel the boat further.
How did the lateen sail help explorers?
In addition to allowing ships to sail closer to the wind, the lateen sail also made ships more maneuverable. … Ultimately, the lateen sail enabled explorers to discover new regions of the world in a way that traditional “square” sails would not have been able to.
How did the lateen sail get to Europe?
The lateen sail, developed during the first millennium, was introduced to medieval Europe where it revolutionized marine travel. … Their use in “foreand-aft” rigged ships helped to launch an era of seagoing commerce, exploration, and warfare that continued through the end of the Age of Sail.
How did Lateen Sails contribute to navigation on the Indian Ocean?
Dating back to Roman navigation, the lateen became the favorite sail of the Age of Discovery, mainly because it allows a boat to tack “against the wind”. It is common in the Mediterranean and the northwestern parts of the Indian Ocean, where it is the standard rig for feluccas and dhows.
What is the best sail shape?
The best shape for acceleration has the draft fairly far forward. Upwind — When a boat is sailing into the wind, you want sails that are relatively flat. Flatter sails reduce drag when sailing upwind and also allow you to point a little closer to the wind.
What were lateen sails used for?
Lateen sails were triangular sails which allowed ships to sail directly into the wind, versus the formerly used square sails that did not allow ships to sail into the wind.
What advantages does a triangular lateen sail have?
The sail, its free corner secured near the stern, was capable of taking the wind on either side, and, by enabling the vessel to tack into the wind, the lateen immensely increased the potential of the sailing ship.
How did the caravel help European explorers?
Clearly, the Caravel revolutionized European transportation. This technology made it possible for European explorers, fishermen, and merchants to “expand their horizons,” by providing the ability to travel further, faster. One could argue that it played a major role in the rapid colonization of the New World.
Why was the caravel ship important?
Caravel, a light sailing ship of the 15th, 16th, and 17th centuries in Europe, much-used by the Spanish and Portuguese for long voyages. Apparently developed by the Portuguese for exploring the coast of Africa, the caravel’s chief excellence lay in its capacity for sailing to windward.
Did the Portuguese use Lateen Sails?
The lateen sails gave it speed and the capacity for sailing windward (beating). Caravels were used by the Portuguese and Castilians for the oceanic exploration voyages during the 15th and the 16th centuries, during the Age of Discovery.
What name is given to a sail in the shape of a truncated triangle based on a lateen that was common on Arab dhows and Maltese Gozo boats?
Dhow, also spelled Dow, one- or two-masted Arab sailing vessel, usually with lateen rigging (slanting, triangular sails), common in the Red Sea and the Indian Ocean.
What is a lateen sail and why was it significant in the 1450 1750 time period?
Lateen sail: Triangular sail that allowed ships to sail against the wind, increasing maneuverability and making early oceanic sailing possible.
Who invented the sails?
According to Jett, the Egyptians used a bipod mast to support a sail that allowed a reed craft to travel upriver with a following wind, as late as 3500 BC. Such sails evolved into the square-sail rig that persisted up to the 19th century.
What did caravel ships carry?
History of the caravel. The caravel of the 15th and 16th centuries was a ship with a distinctive shape and admirable qualities. A gently sloping bow and single stern castle were prominent features of this vessel, and it carried a mainmast and a mizzen mast that were generally lateen-rigged.
