Severne SDM cam (camber inducer) for use with SDM (standard 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 black with twin red rollers on marine-grade stainless pins.
These cams can only be used with SDM masts. Using them on RDM (reduced diameter) masts will cause damage to the sail and mast and the sail will not rig or function properly.
