The Case Book, cases are authoritative interpretations and explanations of The Racing Rules of Sailing. The Case Book complements The Racing Rules of Sailing (RRS), providing details on the application of the RRS to around 100 scenarios. The principal aims of the Cases are to clarify an important meaning in a rule or to increase the understanding of a complex rule. A revised edition of The Case Book is published every four years to coincide with the publication of the revised edition of The Racing Rules of Sailing. Then, in each of the following three years a supplement to The Case Book is published.

The ISAF Call Book for Match Racing and the ISAF Call Book for Team Racing provide a clear definition, for both competitors and umpires, how certain incidents will be called in match or team racing events.
