OVERVIEW
US
SAILING, the local IRC Rule Authority, working in relation to the RORC, www.rorcrating.com,
is offering IRC Ratings. The following information offers an
introduction to the rule and should help answer many of your
questions.
ANNUAL
PUBLICATION - To keep you
informed
The IRC yearbook is made available at the beginning of January each year to
holders of certificates from the previous year together with a rating
revalidation form. Apart from the IRC rule, the yearbook provides help
to owners applying for their certificates by way of diagrams and
definitions, race management recommendations, useful names and
addresses, articles from invited authors and much other relevant
information. NEW IRC Rule
2006 (225Kb Word Doc., Dec '05)
ALL
MONO-HULL YACHTS CATERED TO
IRC is capable of applying a rating to any mono-hull yacht. In doing so,
it respects such
features as asymmetric spinnakers, carbon masts, canting keels, and water ballast;
all of which have
been permitted for several years. Furthermore, the rule is reviewed annually in light
of new developments and past results. On this front, RORC seeks and actively
welcome input and comment from the users.
The Basics- IRC permits and encourages owner declared measurement
data- self measurements. These will be
maintained into the future, although some clubs and areas have always
insisted that locally they should measure boats.
Thus, there are "
ENDORSED" IRC ratings. These require that US SAILING, working under
the auspices of the RORC, should be satisfied as to the
correctness of the rated data, generally by measurement by an appointed measurers. Race Committees may require endorsed certificates for
some events. Also, an IRC measurement manual is available on request to assist
with local measurement if required.
The rating one receives is a time-on-time number, with
the higher number being the fastest. For example: 1.850 is faster
than 1.650. Corrected time = Elapsed time X Rating. See
'Ratings Explained' on side bar.

-Measurement
Diagrams and the IRC rule are available here as further reference. -Various
sources of data including a boat's IMS Certificate, brochures, PHRF,
designers/builders, etc., may be helpful in providing data one needs
when applying.
Application
data are asked to be in the metric measurement system, meters and kilograms.
Here are the appropriate conversion factors if needed:
|
Multiply
feet by 0.3048 to obtain meters |
|
Multiply
pounds by o.4536 to obtain kilograms |
3.
Submit the application only after it has been fully completed via email
as an attachment.
Submission of partially
completed applications are discouraged and cause possible delays.
Please consult an IRC Measurer for any assistance.
We
shall like to request ALL applications be emailed as an attachment to:

Upon receipt of fully completed application, IRC certificates are
expected to be returned within 3 to 5 weeks, depending on the time of year. Certificates are valid from 1st
January to 31st December in the USA. Thank you.
STANDARD
CLASS LIST: Boat
classes/models for which IRC Standards have been set in terms of overhangs &
displacement measurements only. Upon
applying for base ratings (non-endorsed), one may elect to have standard Overhang
Dimensions
& a class weight used
towards their IRC Ratings. Racers
shall then need to submit rig, sail, hull data, etc., to complete the application
process. These standard overhang and displacement
values reference the lightest boat in class. Please
state your interests in using these data if desired when applying?
