Abstract
Abstract A sail system in which the sail is reefed or furled by dropping and folding it progressively into a cover extending along the foot. The cover has starboard and port cover sides extending upwardly from the foot and joining cover lifters which are in turn attached to the sail. The cover sides have closure means along their upper edges for fastening them together after the sail and fly have been fully furled therewithin. Lazy jacks extend along each side of the sail and downwardly to the foot. One or more reef lines may each extend from the foot upwards through a cover side, through a reef cringle on the sail, and downwardly to a pulley attached at the clew.
