Effects of wind shear in Sailing and Olympic Sailing Tickets

Wind shear affects sailboats in motion by presenting a different wind speed and direction at different heights along the mast. Wind shear occurs because of friction above a water surface slowing the flow of air. Thus, a difference in true wind creates a different apparent wind at different heights.
Sail makers may introduce sail twist in the design of the sail, where the head of the sail is set at a different angle of attack from the foot of the sail in order to change the lift distribution with height. The effect of wind shear can be factored into the selection of twist in the sail design, but this can be difficult to predict since wind shear may vary widely in different weather conditions. Sailors may also adjust the trim of the sail to account for wind gradient, for example, using a boom vang.
Sailing is related with very old history but now a day’s sailing has become a sport and important part of Olympics. Sailing is coming in London Olympics 2012. You can buy Olympic Sailing Tickets to watch it live. You can purchase Olympic Sailing Tickets from Global Ticket Market. Global Ticket Market offers you all sorts of Olympic Tickets at very reasonable price. Especially, Olympic Sailing Tickets are being sold at very cheap rates at Global Ticket Market.
