Harken Carbo Ratchets allow
sailors to hand-hold loaded lines and offer balance between holding power
and controlled easing. The Harken 57 mm Carbo
Blocks provide precise on/off control with accessible, easy-to-operate
switches on both sides of the block. For the ultimate system, mount a switchable
ratchet in the cockpit and a boom-mounted Ratchamatic directly above for double
holding power in heavy air and a free-running mainsheet when it's light. The
Harken 57 mm Carbo Ratchet Block has a holding power of 10:1.
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 Hardkote
anodized for strength and corrosion resistance. Eight facets hold line securely.
Ball bearings, sheave, and sideplates are UV-stabilized with carbon black for
