Ronstan Series 8 Ballside Car - Batten, Quick Release big block Twin Flat shaft drive -Ronstan Series 8 Ballside Car Batten, Quick Release. 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.
