   note: sails are of two general kinds, fore-and-aft sails,
         and square sails. square sails are always bent to
         yards, with their foot lying across the line of the
         vessel. fore-and-aft sails are set upon stays or gaffs
         with their foot in line with the keel. a fore-and-aft
         sail is triangular, or quadrilateral with the after
         leech longer than the fore leech. square sails are
         quadrilateral, but not necessarily square. see phrases
