New to IRC?
Are you are considering IRC racing but don’t know where to start with getting a rating, or what is involved? Perhaps you have friends who race IRC, or your club has just introduced an IRC class?
To dispel a common misconception that IRC is only for serious racers, this is not the case. IRC rates all types of boats from dayboats through to large heavy classics, and every type in between! We recognise that the process of getting a rating can appear tortuous, but we aim to help you find your way through it...
If you are new to any sort of yacht racing, have a look at the RORC article about how to start racing.
On this site you can find Frequently asked Questions, rules and regulations and additional information, advice to race organisers and other information which applies worldwide. We have Rule Authorities (IRC 'agents') in a large number of countries worldwide, so the first thing to do is look HERE to see if there is a contact for your country.
The IRC 2018 yearbook is available online via the link on the homepage of this site (scroll down to find it). In the Yearbook you can find editorial, the IRC Rule and a great deal of information and advice. If you would like a hard copy please contact your Rule Authority who will be able to send you one.
There is no substitute for the full IRC rule to make sure your boat complies, and you can find these in the Technical/Admin section of this website; however there are simplified rules that cover the basics, on the RORC Rating Office website HERE.
Help with measurements:
For production boats we are likely to hold standard hull data, that is the length, beam, draft, weight and bow and stern overhangs. That means that we only need the rig and sail measurements, plus the additional details which are specific to your boat, such as furling headsails and propeller type. It probably seems tedious having to give us all the details of your boat, but it means that the rating will reflect your specific set-up.
You can find some simplified measurement guidance on this site. This section is a work in progress so if you have any ideas for other 'simplified guidance' that is not already covered elsewhere on this site, please e-mail , thank you.
If you prefer a measurer to come and help then your Rule Authority can arrange that too. The measurement page HERE gives lots of advice about how to measure to the IRC Rules.
Once you have had a browse around the sites, if you have more questions please talk to your Rule Authority, or use the contact form on this site if you are in a Country without a Rule Authority.
