Waves are formed due to the friction of the wind over the water surface. The three main components for wave generation are the wind speed, it's duration and fetch.... How to recognise a swell/wave generating area. On a weather chart there are high and low pressure systems. They are separated by isobars(lines joining places of equal pressure). Buys Ballot's law states :"If you stand with your back to the wind in the northern hemisphere, the low pressure will be on your left. "From this you can deduce the wind flows anticlockwise around a low pressure system and almost parallel to the isobars. The wind near the surface actually flows at an angle of about 15 degrees to the isobars pointing in to the low. The reason for this is that friction with the surface slows the air down and it is this friction which causes waves to form. Assuming you have identified an area of closely packed isobars which are almost straight for 200 miles and the low system is not changing to quickly, you have found a good swell generating area.  3, fiche 1, Anglais, - wave%20generation%20area

If the sails are out too far or the boat is pointing too close to the wind, the forward edges of her sails will shiver or even shake violently, and this is called "luffing". A boat cannot sail efficiently when her sails are luffing.  5, fiche 2, Anglais, - flap
