The CARBO RATCHAMATIC automatic ratchet block from Harken with 57mm disc diameter is ideal as a main sheet block for small dinghies such as the Optimisten or the 420, in order to be able to pull the sheet out of the hand even under load and to work effortlessly. Also on larger ships and small yachts this block is often used for the sheet systems. The disc locks automatically under load while running freely in both directions at low pressure.
