This Harken 75 mm Carbo Ratchamatic block is an automatic load-sensing ratchet block for efficient line handling on board.
The block free-runs in both directions under light loads and automatically engages the ratchet mechanism as the load increases. This provides better control and more efficient trimming without the need for manual activation.
With 1.5x holding power, a 22:1 holding force ratio, and a capacity for lines up to Ø12 mm, it is well-suited for demanding sailing where precise control and high reliability are essential.
