ILCA 4 MKII Class Legal Sail

The ILCA 4 MkII uses a more robust 4.93 oz cloth and adopts a bi-radial construction better suited to modern stiffer materials. Additional updates include:

• A larger sail window
• Standardized reinforcement patches
• An updated batten configuration, aligned with the MkII sail family
• A look-and-feel closer to the ILCA 7 MkII, improving consistency across the MkII range

These changes are intended to improve durability and consistency while minimizing the impact on costs.

Commercial release of the ILCA 4 MKII sail started early April 2026. ILCA’s intention is for the sail to become class legal in early August 2026, in time for the ILCA 4 World Championship, subject to final confirmation. The current ILCA 4 sail will remain fully class legal.

Please note: The MKII battens will be different from the current ILCA 4 sail.

The ILCA 4 MKII Sail is ILCA Class Legal.
