This veil is part of family aft sails. It still increases performance by reducing the entire surface of mast backwards, releasing the front portion thereof for the installation of jibs. The shape of a sail that dumps a lot at the horn, making it less effective but still allows large sails to carry a short mast (Key West sail and snorkel). Constraints have allowed only very recently to get closer without having to use many spars and running rigging, whose weight and windage often compensate for the gain provided. It was used since ancient times known way from the Baltic to Mediterranean on merchant and military vessels, whether sea or river.
In ninth century the introduction of lateen begins the decline sailing in Mediterranean where the wind regime is too irregular to use it. Atlantic it persists even beyond the Middle Ages, Viking long ships to Hanseatic cogs, through the French and British ships. The following centuries confirm its retention as evidenced ships products both for trade and for the fight.
The luff of mainsails is secured to mast or through the slides set sails and passed through the mast or through a rope (that is to say a rope sewn along sailing). The edge of mainsails is held by a rope or a / the slide (s) passed into groove of boom. A spinnaker (spinnaker) symmetric by definition, tack and luff are side pole (after jibe so do these terms mean the same most of sails).
The force exerted by wind on sails is roughly perpendicular to chord of sails plan. The component of force which is parallel to axis of vessel is the propulsive force. The other component, perpendicular to axis of vessel tends to cause it to drift, but can also cause property (band) (the ship leans on its side), and can dangerously compromise its balance or capsize.
When the ship goes back to wind, the wind flow along the veil creates a pressure difference between the windward side (underside) and leeward (suction). In fact, depression is formed on the upper surface, which "pulls" the ship, allowing it to go upwind. This same phenomenon applied to an airplane wing, which allows him to fly.
At its inception this veil was little different from the square sails, his yard is horizontal, but with significantly improved performance upwind, including "topping lift" of yard, that is to say, the yard becomes more vertical in approaching the axis of mast.
This sails had its heyday In river navigation: easy to implement, it was adapted to folding or removable masts various vessels such as barges, barges, and some barges. Among the boats that brought this rig to perfection, we have the Thames barges which some copies still sailing today at the marina, while others lie dormant in a museum.
It is found in the early twentieth century in, in northern Brittany, in particular the number of cutters fishing inBay of Morlaix; ex. Joan of Arc, launched in 1909. The advantage of this simple to implement rig is a certain lightness, excellent performance of near-like while maintaining a large area of canvas suitable for speed (first come port obtained the highest price for their catch, fresh issue as well).
