The 57 mm and 75 mm switchable ratchets provide precise on/off controll with accessible easy to operate on/off swithches 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 75 mm provides up to 15:1 holding power; the 57 mm 10:1. Carbo Retchets allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing. Nylon resin saideplates are densely packed with long glass fibers for a compact block with high strength to weight ratio. Machined aluminum sheaves are hard cote annodized for strength and corrosion resistance. Eight facets hold line securely. Bala bearings, sheaves, and sideplates are UV-0stabilized with carbon black for maximum protection.
