About ILCA

The ILCA (International Laser Class Association) manages the world-famous single-handed dinghy class, often called the Laser. ILCA boats are sailed in thousands of clubs worldwide and are used in local, national, and international competitions, including the Olympics. The class is known for being simple, fun, and highly competitive, offering a true test of sailing skill. ILCA also organizes events, promotes fair one-design racing, and supports a global community of sailors, from beginners discovering the sport to experienced racers chasing championships.

ILCA versus laser

The Laser dinghy, one of the most popular single-handed boats in the world, is now officially managed by the International Laser Class Association (ILCA). The name change started in 2020 to ensure standardized class rules, official governance, and a network of approved builders worldwide. Boats built before this change are still legal for racing if they meet ILCA specifications, and all new ILCA boats are fully approved and legal for all official competitions. Today, all ILCA races require boat builders to build boats conform to the class rules, ensuring fair one-design competition.

ILCA 4, 6 and 7 differences

ILCA rig options, ILCA 4, 6 or 7

The ILCA 4, 6 and 7 share the same hull but have different rigs to suit various sailor weights and skill levels.

  • ILCA 4: Smallest sail and shorter, pre-bent lower mast, ideal for lighter sailors and youth.
  • ILCA 6: Medium sail with a more longer lower mast; carbon upgrade available to guarantee a stiff mast over time
  • ILCA 7: Largest sail and even longer lower mast, built for heavier and more experienced sailors.

ILCA bottom masts

ILCA bottom mast differences, ILCA 4, 6 and 7.

The ILCA 4, 6 and 7 use different lower mast sections to match their sail sizes and sailor weight ranges. The ILCA 4 has a shorter, pre-bent lower mast, the ILCA 6 a more flexible section, and the ILCA 7 a stiffer lower mast to handle higher loads.

For ILCA 6 sailors, a carbon lower mast upgrade is available. Compared to aluminium, carbon retains its stiffness better over time, providing more consistent and responsive performance, especially for competitive sailing.

Maintenance & tips

ILCA maintenance and tips, cleaning, protecting and repair.

Proper maintenance keeps your ILCA performing at its best. Teflon mast disks reduce friction between the mast and mast step, allowing smoother rotation and preventing wear of your mast and mast step. Mast protection tapes help prevent wear of the mast step and lower mast.

Regular cleaning keeps the hull free from salt, dirt and oxidation, maintaining both appearance and performance. Applying daggerboard tape to the daggerboard can help reduce damage on your daggerboard case in the hull.
