WebBy dividing the sailplan into separate, smaller, sails. Almost all square-rigged vessels also have a fore-and-aft rigged mast, mizzen, to enable rising towards the wind and to ease steering. While square sail is the most effective running sail there is, it is not good on rising towards the wind. WebThe case is similar for sailboats. A sail is almost always curved and presented to the wind at an angle of attack.
