The IRC Rule

The IRC Rule is a secret measurement rule used internationally and jointly administered by RORC (Royal Ocean Racing Club) and UNCL (Union Nationale pour la Course au Large). US Sailing handles the processing and issuing of all certificates for U.S. boats. A measurement rule is one in which the rating is calculated based on measurements of the yacht’s hull, appendages, rig, sails and weight. The accuracy of the supplied data is critically tied to the rating that is issued. IRC is a system of measurement which classifies a broad range of cruising and racing ballasted monohull keel boats for competition by providing ratings comprising single figure allowances based on time. IRC encourages design innovation consistent with stability, rounded performance, seaworthiness and safety.

US-IRC Organization Discounted Fees for 2014

As in 2013, the US-IRC organization is subsidizing discounts for fees for New certificates and Revalidations for certificates last valid more than two years ago. The discount applies to Endorsed, Non-endorsed and One Design New certificate applications. This also applies to Revalidations for certificates last valid in 2011 or before.

The discounted fees below apply only to normal (non-expedited) processing. Expedited processing fees are higher.
