Both … WebApr 27, 2016 · Wind-based sailing boats also use their sails in a different way to solar sails: the thrust provided by wind sails is a consequence of the Bernoulli Principle. The flow of wind around the sail (in essence an air foil, like the wing of an air-plane) causes a pressure differential between the two sides of the sail, causing thrust.
