ILCA Mainsheet Blocks

ILCA Mainsheet Blocks

Introducing our approved, class-legal ILCA mainsheet blocks, developed and extensively tested to deliver smooth, reliable mainsheet performance. Designed specifically for ILCA racing, the system combines low-friction ball bearing blocks with a purpose-designed plain bearing traveller block to optimise both trimming efficiency and traveller control.

All blocks, except the traveller block, feature lightweight Delrin ball bearings for fast sheave rotation and effortless mainsheet trimming. The traveller block uses a plain bearing sheave, providing enough friction to help keep the traveller positioned correctly on the corner of the boat when sailing upwind under load.

The linked traveller blocks are connected with a riveted body that allows sufficient articulation for correct alignment when fully sheeted in. This eliminates the need for the traditional practice of wrapping traveller blocks in electrical tape to increase stiffness.
