ILCA has announced the upcoming launch of a redesigned ILCA 4 sail.
The new ILCA 4 MkII sail was developed to improve cloth supply and improve durability without changing the ILCA 4 rig or compromising the ILCA one-design principle. For many years, the ILCA 4 sail has depended on a 3.8 oz sailcloth that is no longer produced at scale. The ILCA 6 also uses the same 3.8 oz material, and so work has commenced on the development of a future ILCA 6 MkII sail as well.
The new ILCA 4 sail will be available in limited supply from April 2026 and will be class legal from August 2026 in time for our events next season. The existing ILCA 6 sail will continue to be used through to the Los Angeles 2028 Olympic Games with the new model to be released afterwards.
