This Harken 75 mm Carbo Ratchamatic triple block with swivel is designed for efficient line handling, where an automatic ratchet function and free-running capability must work together under varying loads.
The block runs freely in both directions at low loads and automatically engages the ratchet function at higher loads. This provides a smooth transition and makes it easier to handle unloaded lines.
The load sensor can be adjusted as needed, allowing the block to be customized for sailing style, trim, and personal preference. It is well-suited for demanding deck work where control, grip, and reliable operation are essential.
