The IRC Rule is owned and managed by the Royal Ocean Racing Club (RORC) in the UK and l’Union Nationale de la Course au Large (UNCL) in France.
RORC and UNCL are jointly known as the IRC Rating Authority and control the policy, technical development and administrative aspects of the Rule, where all IRC certificates are issued by the rating offices:
RORC Rating Office
Lymington SO41 3SE
UNCL Centre de Calcul
36 Quai Alphonse Le Gallo,
In countries outside the UK and France, local IRC administration is through the local Rule Authorities around the world.
