ILCA Outhaul - 30mm Allen Blocks

ILCA Outhaul System – 30mm Allen Blocks

Upgrade your ILCA with a smooth, efficient top-of-boom outhaul system built around lightweight Allen 30mm Dynamic Tii-On blocks. This setup is a step up from the 20mm version, offering freer-running performance and lower friction, making adjustments even easier — though with a small increase in weight.

The system features a high-strength 3mm SK78 Dyneema primary line, ensuring minimal stretch and precise control of your sail shape.

For the secondary control line, choose from two trusted Robline options:

• Dinghy Control – 4mm SK78 Dyneema core with a durable polyester cover. Smooth, reliable and ideal for everyday sailing.
• Polytech – Technora®/Dyneema® blended cover for maximum abrasion resistance and exceptional grip. The premium choice for heavier use or competitive sailors.

If you sail the ILCA 4 (4.7), simply select the dedicated 4.7-optimised configuration at the bottom of the page for the perfect fit.

This 30mm outhaul upgrade delivers smoother adjustments, reduced friction and race-ready responsiveness — giving you a performance boost over the standard 20mm system.
