The amount of depression (the arch) determine the position of hollow lift coefficient of a sail, where the number of devices which attempt to influence these parameters. As in aviation, when the flow around the wing drop, the wing loses its effectiveness; sailors anxious to know that sailing performance develops its greatest strength when it is close to set back (Key West sail and snorkel).
That's why sailors always changing their settings to keep them as close as possible the separation sails without the to stall. This requires constant attention, because the setting must be adapted to changes in speed, heading, and wind changes. Strands of wool or ribbons (favors) are often set in various parts of hollow sails to materialize flow nets wind, and report the stall.
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.
It was during the first half of twentieth century disappears little by little the veil, especially with the end of tall ships at a premium, one of most successful for the size and speed generations, whose Belem is a survivor, unlike the Duchesse Anne reflecting a generation of great vessels school that bygone period.
One can consider a sails attached flow charge of a system as a deflecting air mass. Just like a shot putter gets a centrifugal force by spinning his hammer, sailing receives is proportional to mass of air deflected and the deflection angle power. The amount of air is deflected from the product:
This can be dangerous, especially on multihulls and cause charging. The hull downwind then abruptly plunges underwater. The resulting violent downturn may capsize the boat on the front (power). At high speed, this speed requires sustained attention of crew.
To avoid when the wind increases, it moves the center of gravity towards the rear, moving crew, use of ballast, for example, depending on the size of boat. It also guides the back and center of buoyancy sailing (or tilt mast rake). Depending on the time and place, the shape of sails vary significantly. The theoretical shape with the best performance in attached flow is a half vertical ellipse whose base touches the surface of water.
