Patented system uses low profile cars running on twin races of Torlon 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.
Bushes can be permanently sewn into webbing loops on mainsail luff.
