The Carbo Ratchamatic is a load-sensing ratchet block designed for optimal performance across varying conditions. It rolls freely in both directions under low loads and automatically engages the ratchet as loads increase. This seamless transition between ratchet and light-air modes ensures efficient handling. The system provides superior grip and holding power for demanding sailing applications.
Load Sensing: Rolls freely in both directions under low loads and automatically engages the ratchet as loads increase.
Seamless Transition: Shifts smoothly between ratchet and light-air modes without manual intervention.
HTE Version: The spring on the high-threshold engage version of the 57 mm blocks is stiffer to delay ratchet engagement.
Free Running: Allows the block to run free more of the time by engaging the ratchet at higher loads.
Gybe Performance: Enables the old kite sheet to run free for crisper gybes.
Grip Ratio: Provides 1.5x grip in breeze-on conditions and puffs.
Holding Power: Delivers 15:1 holding power for secure line management.
