Look up reefing in Wiktionary, the free dictionary.
Reefing reduces the area of a sail, usually by folding or rolling one edge of the canvas in on itself and attaching the unused portion to a spar or a stay, as the primary measure to preserve a sailing vessel's stability in strong winds. Restoring full sail area is termed shaking out a reef.[1]
Whereas fore-and-aft rigged vessels store the unused portion of the sail on a boom (below the sail), square-rigged vessels stow the unused portion on a spar above the sail. Reefing may occur by rolling the sail around its luff or foot, either on a rotating stay or within a spar.
