COMPACT SELF-ALIGNING MAINSAIL TRACKING TURRET + BLOCK

A5266COMP - Compact Self-Aligning Mainsheet Jammer – Low-Profile Automatic System

The market's only compact self-aligning mainsheet jammer, delivering automatic hands-free jammer rotation through tacks and gybes with reduced deck height for enhanced cockpit ergonomics.

Advanced Self-Aligning Technology:
The innovative self-aligning mechanism utilizes an offset ratchet block configuration for automatic orientation.

By positioning the block outward from the swivel centerline and angling it away from the cleat, the A5266 mainsheet system generates continuous rotational force on both block and jammer, automatically directing the cleat away from the boat's leeward side throughout maneuvers.

This intelligent offset design eliminates sheet wrap around the block and provides exceptional control for rapid, seamless tacks and gybes, reducing crew workload during critical sailing moments.

Watch the demonstration video below to see the self-aligning system in action.

Available in two configurations: standalone compact jammer or complete assembly with integrated 60mm Pro-Ratchet block.

Features precision cold-forged bearing technology with ball-retention groove, ensuring smooth, friction-free rotation while eliminating lateral arm movement for reliable automatic alignment.
Adjustable rotation capability of 180°, 220°, or 360° through repositionable stopper pins located on the arm's underside, allowing customization to suit various boat layouts.
Optimized jammer arm geometry guarantees effortless line engagement and quick release for precise sheet trimming.
