Patented system uses low profile cars running on twin races of Acetal ball bearings. Cars use the existing luff groove of the mast (no track or installation work required). Ball bearings are captive for easy loading and unloading of cars from mast. They can be easily switched between fully battened and "soft luff" mainsails. Minimum distance from mast to mainsail luff enhances mainsail efficiency.

Applications:

• Monohulls to 18m (60ft) or sail area 60 m2 (646 ft2)
• Multihulls to 13m (43ft) or sail area 48 m2 (517 ft2)

Materials:

• Alloy car bodies
• Torlon ball bearings
