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).
The three angles of sails (a triangular sails) have a specific name: The head point is the angle at the top of web once hoisted it: this is where the halyard is hit. The tack denotes the angle attached tofixed point of boat: when sails is in position, the tack is on the front of boat. The clew refers to angle of sails which was struck listening (jib) or near which rose listening (mainsails)
To improve the performance sailboats, speedboats architects also influence the shape of mast (wing masts) to further improve these flows. Resembling the close, sailing has a propulsive force as its angle relative to apparent wind is still large enough (about twenty degrees). This has the consequence that it is possible with a vehicle with a low resistance to progress, to go faster than the true wind. This is the case for example windsurfers, multihulls, mono hulls designed some of Planing and tanks to sails. Craft being the fastest sailing ice tanks capable of reaching four to five times the speed of wind.
The operating principle of a sails depends on the speed of vessel, that is to say the direction of ship to wind. A sails works in two ways: Either flow attached which shows a phenomenon of lift to paces from close to reaching, Is flowing hook, and a board that we would position perpendicular to wind. This is the mode that looks grand and dropped downwind.
When the ship away from the wind, the flow along sails can "win." The wind literally pushes sails. To obtain maximum propulsion, it is then necessary to orient the web so as to be differently perpendicular to axis of wind. It should also set sails so that it is as hollow as possible. Extremely hollow sails were designed for this purpose, such as spinnakers (or "spinnakers") or gennaker.
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 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.
Ideally, therefore, a web has a curved profile, the profile being in front of axis of wind, and the back of profile in axis of vessel. The distance between the leading edge and the trailing edge should be as short as possible to reduce friction (drag), while being long enough to distribute the vacuum. Depression is much stronger that the forced air flow direction deviates from the axis of wind. We can therefore provide for a higher radius of curvature at the front of profile backwards. This results in an asymptotic optimal profile, where in hollow is located in first third of profile.
