The IRC Rating Rule continues to strengthen its position as the unifying measurement system for top-level offshore competition, as two of the sport's most prestigious team events — the Sardinia Cup 2026 and the Admiral's Cup 2027 — confirm they will share the same IRC framework.
The Royal Ocean Racing Club (RORC) and Yacht Club Costa Smeralda (YCCS) have aligned their events under consistent IRC rating bands, enabling teams to transition smoothly from the Mediterranean's Sardinia Cup to the UK's Admiral's Cup the following year. This alignment creates a natural bridge between two cornerstone international regattas, reinforcing IRC's reputation as the global standard for fair, competitive yacht racing.
Used worldwide for everything from local club races to major international championships, the IRC Rating Rule is a simple, single-number system that allows different designs of boats to race together fairly. Its accessibility and clarity make it easy for sailors to understand and for race organisers to implement — whether the racing is inshore or offshore, local club events or international grand-prix competition.
The Sardinia Cup returns to Porto Cervo from 31 May to 7 June 2026, marking a new chapter for the historic event after more than a decade's break. Registration is open, with national and club teams expected to compete in a week of inshore and offshore racing under IRC.
The Admiral's Cup, which will follow in 2027, remains one of the most revered trophies in offshore sailing. Its Notice of Race, recently published, confirms that the regatta will continue its tradition of combining inshore racing with the offshore challenge of the Rolex Fastnet Race — all within the IRC framework.
RORC Commodore Deb Fish highlighted the significance of the collaboration, noting that "by aligning under the IRC rating rule, we're giving teams continuity and a clear pathway between two world-class events."
For sailors and yacht clubs worldwide, the coordinated approach between RORC and YCCS demonstrates how the IRC rule continues to bring structure, fairness and unity to the sport — linking historic regattas and modern competition under one trusted measurement system.
