Harken's Carbo AirBlock® has an enormous working range, with a higher working load than standard blocks, even though it is lighter in weight! 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. Changing gears between ratchet and light air modes is crisp and seamless. Unloaded mainsheets run like greased lightning during mark roundings. A simple twist of an Allen wrench adjusts the ratchet engagement to a higher or lower load to suit your strength or sailing style.
Use with #28-2629 base block for a 6:1 carbo low-profile mainsheet system.
