Page 5 - Call Book for Team Racing 2017-2020

Preface

This is the sixth edition of the World Sailing Call Book for Team Racing. It has
been edited to reflect the changes in the Racing Rules of Sailing for 2017 – 2020
and in particular the rules of Appendix D. Special thanks to members of the Match
& Team Racing Rules Working Party: Marianne Middelthon, Rob Overton, Mike
O’Connor and John Pratt for their help in updating this book.

Whilst most of the changes are simply changes in references, there are some
significant game changes involved and sailors and umpires are well advised to
study the new call book in detail! All major changes are a result of a significant
rule change or of a submission to change the call.

The following is an incomplete list of changes:
 There is a new General Principle about Advantage Gained.
 Call L2 is deleted. Call E8 is withdrawn for review.
 Call L9 is new since the 2016 Supplement. Previously, this was rapid
response call 2016-001.
 The decisions in calls C3, D2, E14, H1, H2, J7, K1 and L3 are completely
or partially changed.
 In addition, there are insignificant changes in many calls and in many rules
references that do not affect the substance of those calls.
The purpose of this call book is to define, for umpires, judges and competitors
how incidents will be called in Team Racing.

The calls are split into sections associated with progress around the course, citing
typical incidents in the order they are likely to occur and explaining the rules that
are applicable. As a result, some calls are simpler than others, and some include
repetitions from earlier explanations. While calls are printed in one section only,
this does not mean that they do not apply at other times. Many calls (e.g. those in
the prestart section) will apply at all times.

Diagrams are limited to 2-dimensional snapshots of each situation. They cannot
show wind strength, the waves, the heel and speed of boats and all the many other

things that contribute to a real-life scenario. They should therefore not be used too
literally, but rather as a tool to help recognise quickly and clearly the situation
being addressed.

The calls in this book cannot cover every possible incident. As new tactics are
developed, new calls will be required. Should reading this call book, or an incident
