Other forms: furling, furled
To furl is to roll a sail up and tie it. Furl the sails, furled tight, a furled umbrella.
It is the opposite of unfurl, and the tying is part of it — a sail dropped loose is not furled. Flags, awnings and umbrellas take the word too. Modern yachts have roller furling, which winds the sail round the stay instead of gathering it by hand.
