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. With a complete range of car profiles and feet there is a Ballslide™ solution for most available mast profiles and luff groove shapes on boats up to 12m (40ft). See Range Selection Advice for more information. Ballslide™ Car Profile Identification Table.
