Ordering Battcar Systems

1. Determine System Size

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.

 

3. Choose endstop kit

Quick-release: Includes screwpin or pinstop endstop for bottom of mast and fixed endstop for the top.

Fixed: Includes two fixed endstops.

4. Choose cars

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.
