The four sizes, Systems AA, A, B, and C, are based on sail area. If you need to reduce car stack height on mast, contact Harken about our Switch T-Track Battcar Systems.

Track extends above sail luff. Using screwpin endstop kits will increase lengths.
Slug-mount: Most common. Requires 1 slug-mount kit per track section. Select slug that matches the mast's bolt rope groove shape.
Drill-tap: For masts without a bolt rope groove. Requires 1 splice link at each track joint.
Quick-release: Includes screwpin or pinstop endstop for bottom of mast and fixed endstop for the top.
Fixed: Includes two fixed endstops.
Order 1 headboard, 1 Battcar for every full batten, and use the Intermediate Car Chart to determine number of intermediate cars.

*Boats without full battens should use 1 intermediate CB or Slider car per 1.2 m (4 ft) and no Battcars.
CB system: All captive ball bearing components. Lowest friction system for fast sail hoists, douses, and reefs.
Combination system: CB headboard and Battcars, Slider intermediate cars. Reduces cost but uses CB in the most critical load areas.
Slider system: All Slider components. Raise and lower sails without jamming the sail in the groove.
