Wishbone Boom
A boom, in the context of windsurfing, is a piece of equipment that attaches to the mast, providing structural support for the sail. It completely encircles the sail, and is designed to be gripped, allowing the sailor to control the sail for normal sailing, and also for almost any type of maneuver (such as gybing, tacking, and waterstarting). Early pre-RAF/cambered booms (often called a "''wishbone boom''" due to their symmetrical shape) were tied onto the mast using rope, but newer booms use a clamp mechanism for attachment. Application A windsurfer uses the boom to hold and maneuver the rigged sail, either directly gripping it in their hands, or through the use of harness lines. The boom mast attachment is the inhaul, the boom sail attachment (at the opposite end) is the outhaul and there is usually a connection at the boom head to attach an uphaul which is secured to the mast base with an elastic bungee cord allowing the rider the ability to lift the sail out of the water. ...

Windsurfing
Windsurfing is a wind-propelled water sport that is a combination of sailing and surfing. It is also referred to as "sailboarding" and "boardsailing", and emerged in the late 1960s from the Californian aerospace and surf culture. Windsurfing gained a popular following across Europe and North America by the late 1970s and had achieved significant global popularity by the 1980s. Windsurfing became an Olympic sport in 1984. History Newman Darby of Pennsylvania created a rudderless "sailboard" in 1964 that incorporated a pivoting square rigged, "square rigged" or "kite rigged" sail which allowed the rider to steer a rectangular board by tilting the sail forward and back. Darby's design however had notable performance limitations. Unlike the modern windsurfer design, Darby's sailboard was operated "back winded", with the sailor's back to the lee side of a kite-shaped sail. This much less efficient and less desirable sailing position is opposite of how a modern windsurfer is operated. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jibe
A jibe (US) or gybe (Britain) is a sailing maneuver whereby a sailing craft reaching downwind turns its stern through the wind, which then exerts its force from the opposite side of the vessel. It stands in contrast with tacking, whereby the sailing craft turns its bow through the wind. In this maneuver, the mainsail will cross the center of the boat while the jib is pulled to the other side of the boat. If a spinnaker is up, its pole will have to be manually moved to the other side, to remain opposite the mainsail. In a dinghy, raising the centerboard can increase the risk of capsizing during what can be a somewhat violent maneuver, although the opposite is true of a dinghy with a flat, planing hull profile: raising the centerboard reduces heeling moment during the maneuver and so reduces the risk of capsize. The other way to change the side of the boat that faces the wind is turning the bow of the boat into, and then through, the direction of the wind. This opera ...

Tacking (sailing)
Tacking or coming about is a sailing maneuver by which a sailing craft ( sailing vessel, ice boat, or land yacht), whose next destination is into the wind, turns its bow toward and through the wind so that the direction from which the wind blows changes from one side of the boat to the other, allowing progress in the desired direction. Sailing vessels are unable to sail higher than a certain angle towards the wind, so "beating to windward" in a zig-zag fashion with a series of tacking maneuvers, allows a vessel to sail towards a destination that is closer to the wind than the vessel can sail directly. A sailing craft whose course is downwind jibes (or "wears" if square-rigged) by having the apparent wind cross the stern from one tack to the other. High-performance sailing craft may tack, rather than jibe, downwind, when the apparent wind is well forward. Beating to windward Sails are limited in how close to the direction of the wind they can power a sailing craft. The ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterstart
A waterstart is a key windsurfing maneuver for recovering after a fall and getting back into sailing position by using wind. It is more efficient than ''uphauling'' the sail (standing on the board and lifting it by the rope, or ''uphaul''), but requires a minimum level of wind to perform. Variations of waterstarting include the clew-first waterstart and the light wind waterstart. Overview During a waterstart, a sailor clears the sail of water and powers it up in the wind. The powered sail then pulls the sailor out of the water enough so they could step up and onto the board. When the sail is first being lifted, it often helps to push the back of the board slightly underwater, and setting the front of the boom onto the board (near the footstraps). The buoyancy of the board will then push the boom upward, helping to lift the sail out of the water. Waterstarting is faster and less tiring compared to climbing back on the board and uphauling the sail, but requires enough wind (about ...

Buoyancy
Buoyancy (), or upthrust, is the force exerted by a fluid opposing the weight of a partially or fully immersed object (which may be also be a parcel of fluid). In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus, the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and (as explained by Archimedes' principle) is equivalent to the weight of the fluid that would otherwise occupy the submerged volume of the object, i.e. the Displacement (fluid), displaced fluid. For this reason, an object with average density greater than the surrounding fluid tends to sink because its weight is greater than the weight of the fluid it displaces. If the objec ...
