Carbo ratchet blocks allow sailors to hand-hold loaded lines and offer a balance between holding power and controlled easing. Nylon-resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Machined aluminum sheaves are Hard Lube-anodized for strength and corrosion resistance. Eight facets hold the line securely. Ball bearings, sheaves, and sideplates are UV-stabilized with carbon black for maximum protection.
The 57 mm and 75 mm switchable ratchets provide precise control with an accessible on/off switch that is easy to operate from both sides of the block. For the ultimate system, mount a switchable ratchet in the cockpit and a boom-mounted Ratchamatic block directly above for double holding power in heavy air and a freerunning mainsheet when it’s light. The 75 mm provides up to 15:1 holding power; the 57 mm 10:1.
