Abstract
The invention relates to method and apparatus for compactly stacking a sail having a tack, clew and head, the sail being mounted to batten or sail cars above a boom when the sail is stowed, furled or fully lowered. More specifically, most of the cars are compacted or stacked by diverting cars onto several lower tracks, such that the height of the stacked cars is approximately halved. Cars adjacent the boom and tack of the sail may be slidably mounted on at least two of the lower tracks, and carrying the sail between the at least two of the lower tracks. If more than two lower storage tracks are used, the height reduction of the stacked cars can be greater.
