Abcs Of Key West Sail And Snorkel

By Mayra Pierce


A veil is a piece of fabric, which can vary in size from a few square meters to several hundred square meters, which, thanks to wind, is used to move a vessel. Sails are used on sailboats, windsurfers, but also on land vehicles (Key West sail and snorkel). A veil is mainly characterized by its shape, weight, and (s) material (s) which it is composed.

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 compilation and publication in mid-nineteenth century by American captain Matthew Fontaine Maury of wind charts (sum of statistics from the prevailing winds by sectors) on charts has identified roads where the downwind (trade winds, winds commercial) were the most consistent and powerful as these rigs are effective. He contributed to development of so-called large "square-rigged" sailing (for the general appearance they had recalling the silhouette of a lighthouse).

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 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).
