A sail is a surface intended to generate thrust by being placed in a wind; basically it is a vertically oriented wing. Depending on the incident angle of the wind on the surface of the sail, one side of the sail will have a higher air pressure than the other one according to Bernoulli's principle. The difference in pressure will generate lift, causing the sail to be pulled towards the side of lower pressure. ...
