Harken Carbo Ratchets with cams allow sailors to lock off loaded lines whilst also providing low friction sheeting. The cam assembly adjusts and locks in a wide range of positions for crew accessibility. Available with or without becket and in 2 sizes.

Nylon resin sideplates are densely ppacked with long-glass fibres for a compact block with a high strength to weight ratio. Machined aluminium sheaves are hardkote anodised for strength and corrosion resistance. Eight facets hold the line securely. Ball bearings, sheaves, and sideplates are UV stabilised wih carbon black for maximum protection.

All ratchets feature on off switches. These blocks are ideal for main/jib/spinnaker sheets, mainsheet fine-tune, traveller controls, genoa leads and foreguys. For the ultimate system mount a switchable ratchet in the cockpit and a boom-mounted Ratchamatic® directly above to allow double holding power in heavy air and to ensure the mainsheet runs freely in light air.
