How a WINDSURFING SAIL Works in the Wind:
1- When the wind blows on a correctly trimmed sail the air flow separates and passes on either side of the sail.
2- On the leeward side, the wind is accelerated by the built-in curve of the sail. This results in an area of low-pressure
3- On the Windward side. An area of high-pressure is created, thus creating an imbalance in air pressure.
4- This difference in air pressure actually pulls the sail into the wind. More »
How the WIND Works:
Basically, wind is a direct result of horizontal differences in air pressure. Air flows from areas of high pressure to low pressure.
For instance, we are sure that you have experienced opening a can of coffee that has been vacuum packed. The noise that you hear (a pop-pssst type of sound) is caused by air rushing from the area of higher pressure from inside the can to the area of lower pressure outside the can. More »
Windsurfing is a surface water sport using a windsurf board, also commonly called a sailboard, usually two to five meters long and powered by a single sail. The rig is connected to the board by a free-rotating flexible joint called the Universal Joint (U-Joint). Unlike a rudder-steered sailboat, a windsurfer is steered by the tilting and rotating of the mast and sail as well as tilting and carving the board. This method of controlling the board’s direction is called the free-sail system. More »
