   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
