Ronstan’s Ballslide™ system makes raising and lowering the mainsail quick and easy. Recirculating captive ball bearings ensure free running performance, and since the cars use the existing luff groove of the mast there is no need to install a track.


Compatibility
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 18m (60ft). See page 138 for car and feet details. Selection tables and specification sheets can be downloaded from the Ronstan website.


Performance
Ballslide™ cars run on twin races of recirculating ball bearings specifically designed and oriented for compression loads. Hoisting and dropping the mainsail has never been easier! Ball joint links for batten receptacles and quick release pins for intermediate cars are configured to minimise the distance from mast to mainsail luff.

Flexible solutions

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.

Captive Ball cars use a combination of captive recirculating ball bearings running on the face of the track for compression loads, and sliderods to provide extra strength for high static loads. All bearings are captive, allowing for easy installation and removal.

Luff groove tracks are compatible with ‘soft luff’ and fully battened mainsails, making it easy to change between the two. They may be bonded to carbon masts with special adhesives.

Quick release cars make the job easier when the sail needs to be removed for changeover, repair or stowage.
