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 12m (40ft) or sail area 38 m2 (409 ft2)
• Multihulls to 9m (30ft) or sail area 30 m2 (323 ft2)

Materials:

• Alloy car bodies
• Carbon black Acetal ball bearings
