EXPERIENCE CHANGE
I
t is with great pleasure that we at the Offshore Racing Congress present to
you this new ORC guide. You will find it informative and useful to learn about
this system, which is used in more than 40 countries and 10,000 boats, mak-
ing it the largest science-based rating system in the world.
This publication is intended for all sailors, race managers, event organizers,
measurers, media, and everyone else who has an interest in learning about
how the ORC rating system brings competitive and fair racing to a wide variety
of boat types, from small sportboats to enormous superyachts. Our four key features
in achieving such success is through the use of science, transparency to all rules
and policies, flexible options in ratings and scoring, and being affordable and
applicable toward most boat types.
Since 1969 ORC has been dedicated to providing a professionally managed sys-
tem of measurement and rating rule development for the big-boat racing community
to ensure there is an accurate, consistent and transparent
means of delivering fair handicaps to promote fair and
competitive racing. This is for all levels — Grand Prix and
club-level racing alike — because everyone wants fair
racing.
The recent surge in the growth and popularity of our
rule system and the immense popularity of our continental
and world championship regattas show that our system
is working well. We invite you to come out and race using ORC to experience it for
yourself.
We also hope, whether you are trying ORC for the first time or are just looking to
understand more of what you may already know, that this Guide serves as a good
resource for your understanding of this system.
We wish you the very best luck in pursuing fast, safe and competitive sailing.
