    Product Description

    The Carbo Ratchamatic® is a load-sensing ratchet block that rolls freely in both directions under low loads and automatically engages the ratchet as loads increase. Shifting between ratchet and light-air modes is seamless. Unloaded main and jib sheets run out freely during mark roundings and asymmetrical spinnakers free instantly during jibes.

    Ratchet engagement may be adjusted to a higher or lower load according to strength and sailing style. The Ratchamatic® cheek block mounts on either port or starboard. The 75 mm is up to 15:1.

    For the ultimate system, mount a Ratchamatic® on the boom above a cockpit-mounted switchable ratchet to allow the mainsheet to run freely in light air and to double holding power in heavy air.

    Use for:
    Main/Jib Sheets and Asymmetric spinnakers.

    Part Number: 2680
