The Harken Carbo Ratchets allow sailors to hand-hold loaded lines and
offer 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 Hardkote anodized
for strength and corrosion resistance. Eight facets hold
line securely. Ball bearings, sheave, and sideplates are
UV-stabilized with carbon black for maximum protection.
The 57 mm Harken switchable ratchets provide
precise on/off control with accessible, easy-to-operate
on/off switches on both sides of the block.
For the ultimate system, mount a switchable ratchet in
the cockpit and a boom-mounted Harken Ratchamatic® directly
above for double holding power in heavy air and a
free-running mainsheet when it's light. The 57mm 10:1.
Use for:
Main/jib/spinnaker sheets, Mainsheet fine-tune, Traveler controls, Genoa leads and Foreguys.
