The Racing Rules of Sailing (RRS) are revised and published every four years by World Sailing, the international authority for the sport. The RYA, as the World Sailing, Member National Authority for the UK, makes ‘National Prescriptions’, (which are variations to certain areas within the rules) and publishes them together with other addenda in this very handy, pocket sized, spiral bound waterproof publication. This edition has been updated to reflect the Racing Rules of Sailing 2025-2028 and is the essential reference text for every racing sailor, club and race official. This publication also uses coloured pages to quickly identify and access the section on ‘When Boats Meet’ to help racers keep out of trouble. Please note: This is the only publication available that include the RYA’s National Prescriptions which are essential to understand for racing in the UK.
