Equipping your mainsheet system with Harken's Carbo Ratchamatic is akin to having a Tiptronic transmission on your car.
This load-sensing ratchet block rolls freely in both directions under low loads, and automatically engages the ratchet when the load increases. It's great for mainsheet and asymmetric spinnaker sheet trim. A simple adjustment with an hex key can customize the Ratchamatic to differ trimmers' strength.
This single is equipped with a 75mm (7/16 in) sheave and a becket.
