 Each of "Maltese Falcon"s masts supports six yards, which, unlike a conventional square rigger, have built-in camber of 12%.The fifteen square sails are set between the yards in such a way that when deployed there are no gaps in the sail plan of each mast, enabling them to act as a single airfoil.The furling sails are stored in the mast and can be deployed along tracks on the yards in 6 minutes.
