The Power3 ratchet blocks are designed for sailors competing in small one-design classes, offering three distinct holding-power options to adapt to varying wind and sea conditions. This versatility allows for fine-tuning of setups to achieve the ideal balance of power, responsiveness, and grip. The Carbo Ratchamatic is a load-sensing ratchet block that rolls freely in both directions under low loads. It automatically engages the ratchet mechanism as loads increase, ensuring seamless shifting between ratchet and light-air modes.
Load Sensing: The Carbo Ratchamatic rolls freely in both directions under low loads and automatically engages the ratchet as loads increase.
Seamless Transition: Shifting between ratchet and light-air modes occurs seamlessly without manual intervention.
Holding Power: The 2x grip option provides a 20:1 holding power ratio, optimized for big breeze and steady wind conditions.
