Harken 57mm Carbo Ratchamatic Block – RED
Automatic ratchet engagement for smooth, responsive control
The Harken 57mm Carbo Ratchamatic Block – RED features a load-sensing ratchet that engages automatically when the load increases, delivering precise grip when you need it and free-running ease when you don’t. Ideal for mainsheet and spinnaker systems on high-performance dinghies and small keelboats, it combines lightweight composite construction with smooth, reliable performance. The red sheave indicates higher holding power, ideal for heavier loads or gusty conditions.
