ILCA 4 Laser Sail MK2 - Class Approved

Elevate your sailing performance with the official ILCA 4 MkII Sail, the latest evolution in the world’s most popular youth one-design class. Formerly known as the Laser 4.7, the ILCA 4 is the perfect stepping-stone rig for lighter sailors (ideal weight range: 55–65 kg / approx. 45–60 kg), delivering exciting racing on the same hull used in the Olympic ILCA 6 and ILCA 7 classes.

Class Legal Status: Officially ILCA and World Sailing approved. Class legal for all official events from 1 August 2026 onward (commercially available since April 2026). The MkI sail remains fully legal — no mandatory upgrade required, giving you flexibility.

Features

• Includes the official ILCA Authorized Sailmaker button/patch and sail bag.
• Premium Durable Construction: Made with robust 4.93 oz cloth (upgraded from the previous 3.8 oz) and modern bi-radial panel layout. This provides superior shape retention, better resistance to stretching in strong winds, and longer overall lifespan.
• Enhanced Visibility & Safety: Larger sail window for improved tactical awareness on crowded start lines.
• Optimized Reinforcements: Standardized reinforcement patches and an updated batten configuration (aligned with the ILCA 7 MkII family) for consistent power delivery and durability.
• Modern Look & Feel: Closely matches the ILCA 7 MkII sail for a cohesive, professional appearance across the MkII range.
• One-Design Integrity: Fully compatible with existing ILCA 4 masts and booms. Performance remains comparable to the MkI, with sailor feedback noting improved responsiveness, more camber in light winds, and better depowering in breeze via enhanced sail controls (especially Cunningham).
