System AA Micro Headboard CB (Ball Bearing) Battcar Assembly - 13 mm Track

System AA components typically suit monohulls to 37 ft (11 m) and multihulls to 30 ft (9 m). Regardless of hull length, the maximum System AA mainsail area for monohulls is 350 ft² (32 m²) and for multihulls it is 275 ft² (25 m²).

The System AA Micro battcar system makes it possible for boats under 35 ft (11 m) to have 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, intermediate cars for attaching the sail between battens, as well as specialized headboard cars.
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.

The mainsail can be removed quickly and easily by freeing the screwpin endstop and sliding the cars and sail off the track. Stainless steel wire guides keep ball bearings captive when the cars are off the track.

• 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
• The headboard assembly uses two cars to handle the high load and is compatible with most mainsails

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
