Ireland's sailing, boating & maritime magazine ISAF Publishes New Supplements To Match Racing and Team Racing Call Books

16th December 2009

The International Sailing Federation (ISAF) has published the 2010 supplements to the current editions of The Call Book for Match Racing and The Call Book for Team Racing.

The Call Books provide a clear definition, for both competitors and umpires, how certain incidents will be called in match or team racing events. Through written and illustrated examples, scenarios that occur in match or team racing events are presented along with the rules applicable to that situation and how and when they should be applied.

Following on from the ISAF Annual Conference in November, there have been a number of new Calls added to both Match Racing and Team Racing Call Books, whilst several calls have been revised.

Marianne Middelthon (NOR), chairman of the ISAF Match and Team Racing Rules Working Party, said for 2010 there are a number of important changes in the Call Books: "The situation is quite special this year, as we have an exceptional number of new calls, all coming from Rapid Response Calls, in both call books, as a direct result of the changes to the rules about marks and obstructions. More new calls are expected during 2010 as well, but then hopefully the new rules will have been explored to the point where the general rules understanding and the then existing calls will be enough to achieve a consistent approach to the games of team and match racing."

These new Calls and Revisions have been published as Supplements to the current editions of the Call Books. The full text of both Call Books has also been updated. The Supplements and full texts are all available to download from the ISAF website at

A summary of the changes made is:
