A sail is flaked down on the boom. A line is faked down on deck in loose figure eights in preparations for running. If it's coiled flat it's flemished. Flake with regard to laying out line is a mispronounciation of fake, but there's a lot of that, even among seasoned sailors. Many fishermen insist on pronouncing "hawser" as "howser", just as many weekend sailors refer to "knots per hour." But don't get me started on that one.
