Severne RDM cam (camber inducer) for use with RDM (reduced diameter) masts. These take just a few seconds to install onto the batten's inner end of a compatible sail. For use on Severne Moto, Turbo and Overdrive, with or without the little cam spacers that are included with these sails when they are new. Hard-wearing, high quality cam, colour-coded in red with twin black rollers on marine-grade stainless pins.
These cams can only be used with RDM masts. Using them on SDM (standard diameter) masts will cause damage to the sail and mast and the sail will not rig or function properly.
