National Class Rule Interpretations 

The RYA Technical Department is the certification authority for all of the national classes. As such the department issue and publish interpretations associated to the national class rules.

In the downloads tab to the right all of the current class rule interpretations for the RYA national classes can be downloaded as of January 2012. Each interpretation will reference a set of class rules and that interpretation is a supplement to the mentioned class rules. When class rules are subsequently amended the interpretation becomes invalid.
