Self Aligning Mainsheet Jammer - Compact

Compact Self-Aligning Mainsheet Jammer

Designed to deliver smoother, faster manoeuvres, this Compact Self-Aligning Mainsheet Jammer automatically positions itself through tacks and gybes without manual adjustment. By offsetting and angling the ratchet block away from the cleat, the system generates a turning force that keeps the jammer pointing away from the leeward side of the boat, preventing sheet wrap and improving mainsheet control.

Built around a cold-forged bearing system with a ball-locating groove for smooth rotation and reduced lateral movement, the jammer arm can be configured to rotate through 180°, 220°, or 360° to suit different setups. Supplied with an aluminium cam cleat and Mega Pro-Lead, it provides reliable cleating and easy release when needed.
