Fast, simple and reliable. The patented Ronstan Ballslidetm system uses the existing cleat in the mast. It is therefore not necessary to mount a rail. The Ballslidetm carriages have so-called "captive ball bearings", which means that the balls remain in the carriage, even if the carriage is not mounted, and can therefore be easily removed and placed on the mast when the mainsail is to be mounted.
BallslideTM trolleys fit most popular masts and boats up to 60 feet. The full-length ball bearings make it easier and faster to hoist and lower the sail. No rail is required. BallslideTM uses the existing mainsail. The range includes all parts to make a complete system.
