The NEW CCLR has been designed specifically for use with a bolt-rope mainsail for racing boats 20-45ft including Mini 6.5m, Figaro, Fast 40. Designed to receive battens at 45-90 degrees from the mast this works for square-head and pin-head mainsails. A plastic insert fits inside the batten pocket with external carbon shells that run parallel with the luff clamping the assembly to the sail. The design should mean that no bumper is required and the M4 titanium bolts ensure no corrosion will occur. Two sizes are available for solid plate battens and hollow battens, note - the front of the batten may need to be rounded to fit plastic internal profile.
