The Equipment Rules of Sailing (ERS) govern the equipment used in the sport. They are revised and published every four years by World Sailing.

This manual is designed to be a reference guide for existing International Measurers, with the aim of contributing to consistency in measurement / inspection all over the world.

These notes give guidance to equipment inspectors, who may form all or part of a technical committee, at IRSA events with the intention of streamlining the process for the mutual benefit of the customers and race committee as a whole.
