System A - CB Battcar with 40 mm Batten Receptacle

System A components typically suit monohulls to 37-50 ft (11-15 m) and multihulls to 30-40 ft (9-12 m). Regardless of hull length, the maximum mainsail area for monohulls is 600 ft² (56 m²) and for multihulls it is 500 ft² (46 m²).

The System A Battcar system provides an easy-to-use smooth-rolling system, that allows you to hoist and reef the mainsail quickly and efficiently on all points of sail.

These one-piece solid aluminum cars are available in batten versions with a 10 mm threaded stud that fits a variety of batten receptacles, as well as intermediate versions for attaching the sail between battens.
Additionally, cars come in high load ball bearing (CB) versions typically used for batten bearing cars, and lower load Slider versions with low-friction plastic inserts typically used for intermediate cars (between battens).
The matching drill-free track mounts to most masts using a unique slug system that allows installation even with the mast raised.

• Mainsail can be removed quickly and easily by loosening the screwpin endstop and sliding the cars (with the sail) off the track
• Stainless steel wire guides keep ball bearings captive when the cars are off the track
• Compact size of cars reduces stack height when the sail is doused making it easier to attach halyard or put on sail cover

Slider Cars or CB Ball Bearing Cars?
There are three possibilities for car selection when designing a Battcar System:
• All CB System - All captive ball bearing components. This will be the lowest friction system where fast hoists, douses and reefs are a priority
• Combination System - CB Headboard and Battcars (batten cars) with Slider intermediate cars. This reduces cost, but uses low-friction CB cars in the most critical load areas
• All Slider System - All slider components. This will allow you to raise and lower sails without struggling by eliminating the possibility of the sail getting jammed in the groove. You will especially notice the difference when raising and lowering sails in windy conditions
