The Automatic Ratchet Block 40 mm is engineered for sailors who demand maximum reliability, control, and performance in all conditions. Featuring an advanced ratchet mechanism, fully developed in-house by PolarWave, with a 3-tooth holding system for maximum reliability, combined with high-quality ceramic bearings, this block delivers exceptional smoothness and efficiency while remaining extremely lightweight.

In light winds, where sensitivity and low friction are critical, the block runs freely, allowing precise mainsheet control. As the load increases, the automatic ratchet engages seamlessly, providing the holding power needed in stronger winds and significantly reducing the effort required to manage the mainsheet.

Designed to perform across the full range of conditions, this block ensures smooth operation, dependable grip, and consistent performance when it matters most.
