I've been sailing for 40+ years - raced dinghies up to boats across the Gulf of Mexico and this is the first time I ran into a clear (believable) explanation of how the sails work. Airplane wing - it takes longer on the curved side - Bernoulli - low pressure =s lift. I'm an engineer and have lived with that forever - but although a sail may be shaped like the upper edge of a plane's wing - it doesn't have any thickness...
