Sail components include the features that define a sail's shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel (e.g. fore-and-aft) and its shape, (e.g. (a)symmetrical, triangular, quadrilateral, etc.).
A wingsail, twin-skin sail [1] or double skin sail [2] is a variable-camber aerodynamic structure that is fitted to a marine vessel in place of conventional sails. Wingsails are analogous to airplane wings , except that they are designed to provide lift on either side to accommodate being on either tack .
A sail is a tensile structure, which is made from fabric or other membrane materials, that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or ...
Consequently, a sailboat experiences a wider range of apparent wind angles than does an ice boat, whose speed is typically great enough to have the apparent wind coming from a few degrees to one side of its course, necessitating sailing with the sail sheeted in for most points of sail.
Boats may be sailed using a jib alone, but more commonly jibs make a minor direct contribution to propulsion compared to a main sail. Generally, a jib's most crucial function is as an airfoil, increasing performance and overall stability by reducing turbulence on the main sail's leeward side. [1]
Winning the America's Cup is the greatest achievement in the sport of sailing. The trophy is awarded to the yachtsmen and women who win the maritime race that is the oldest and longest-running...
The RS200 utilises a single line asymmetrical spinnaker system and low sheet loads on the sail controls. It can be sailed successfully by pairs of sailors with combined weights of between 16 stone (100 kg) and 26 stone (170 kg). Both sailors hike; there are no trapezes or wings.
The primary advantage of adjusting the cunningham is the speed and ease with which the luff tension can be changed while sailing or racing. By either hauling or easing the line, the tension in the luff can be changed, thereby shifting the point of maximum draft of the sail forward or aft respectively, optimizing sail shape and thus performance ...
