Harken 57mm Ratchet Block — Swivel, 1.5x Grip is a high-performance ratchet block designed to deliver enhanced control and holding power in changing wind conditions. Featuring Harken’s Power3 system, this version provides 1.5x grip, making it ideal for breeze-on sailing and gusty conditions where additional control is needed.

Unlike load-sensing systems, this ratchet block features a manual on/off switch that can be operated from either side, allowing sailors to choose when ratcheting is engaged. With 15:1 holding power, it significantly reduces load on the sailor while maintaining smooth, efficient trimming.

The swivel head ensures optimal alignment under dynamic loads, while the lightweight Carbo construction delivers strength and durability without adding unnecessary weight. Ideal for mainsheets, jib sheets and control lines on dinghies, sportboats and small keelboats.
