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 https://www.ronstan.com/marine/battensysformast.asp for more information.

Sailing professionals around the world choose Ronstan batten systems for superior and innovative features combined with race-proven performance and reliability.

• Low profile
• Lightweight alloy car bodies
• With 7 track sizes in the standard product range, there is a system with the right specifications for every boat and sail plan.
• The range includes all elements for a complete system, including headboard plates and batten receptacles.
• Easy track installation using patented slug connectors.
• Ball Bearing cars run on twin races of recirculating ball bearings that engage with the track profile for excellent all round performance, even when reefing while sailing off the wind.

Car bodies are machined to precise specifications, then honed to an exceptional finish before being treated and anodised for maximum corrosion protection. Minimum distance from mast to mainsail luff enhance efficiency Quick-Release batten receptacle cars allow quick and easy removal of the mainsail for changeover, repair or stowage. Stainless steel ball joint links provide movement in all directions and up to 105 degrees either side of centre - also available to suit

RUGGED DURABILITY

Cars run on twin races of Torlon® ball bearings specifically designed for the high compression loads of these systems. Machined alloy end caps ensure precision bearing performance and durability of the cars. Reef cars are available for the larger track sizes for higher strength at critical loading points. 

FLEXIBLE SOLUTIONS

Luff Groove tracks allow racer/cruisers to switch between their "soft luff" racing mainsail and their full batten cruising mainsail. These tracks are usually bonded to carbon masts with special adhesives or mechanically fastened to alloy masts.

INSTALLATION OPTIONS

A patented connector slug system, compatible with a wide range of mast profiles, is available for Series 19 to 30 track sizes. The system enables installation of the track over an existing luff groove without lowering the mast, drilling and tapping for fasteners, or other complications. The slugs are self-locating, for simple, reliable installation.
