By the end of 2008, the Offshore Racing
Council (ORC) will know if they made the
right decision when they launched ORC
International. “So far so good,”
concludes Bruno Finzi, ORC Chairman, and
Alessandro Nazareth, Chairman of the
International Technical Committee.
A
lot of people have claimed that the IMS
rule developed slow and typeformed boats.
Will the new rule prevent such a
development?
- “ORC believes
that all rules are more or less
typeforming. The old IMS rating rule was
often accused to typeform towards slow
boats because of their lack of
stability, obliging boats to get rid of
stability to remain competitive. In the
last few years of IMS this trend was
already partially corrected,” says
Nazareth. He continues: “The new
rule has been developed considering all
the effects of Righting Moment in the
VPP, looking for a correct and fair
treatment of the boats that increases
their stability. A new evaluation of the
Righting Moment that is used by the VPP
was established based on both the RM
measured during the floatation and on a
standard RM derived by the boat
characteristics (Sail Area, Length,
Beam, Displacement). In this way
righting moment will be more related to
sail area and boat dimensions and how
crew tune the sails to reduce heel.

Bruno Finzi, ORC Chairman
“More than this a new corrected
Residuary Resistance curve based on a
LVR (length/volume ratio) function that
could better take into account light
boats’ characteristics was also
implemented. The combination of these
two new formulations (RR and RM) joined
with the aero modifications have been
verified and the results is a VPP that
makes light and stiff boats closing the
handicap gap against the heavy and
tender boats. So this new VPP will
finally erase any need to reduce
stability and if any typeforming still
exists, this will even drive designs
towards stiffer, lighter and safer
boats.
What do you think of
the launch of a new ORC product? Has ORC
succeeded in their work?
It is early to answer
to this as the first certificates was
issued January 1st, but feedbacks are
good, the sailing constituency is
returning positive comments to the new
rule, a lot of interest has been raised
around the world and already hundreds of
certificates (both INTERNATIONAL and
CLUB) have been issued in less than 2
months. Remember that racing season will
begin only springtime in Europe,” says
Finzi.
Allesandro Nazareth, ITC Chairman
What was the goal and
task for ITC when they got the job to
make the new ORC International rule?
"ITC was addressed by
ORC Management Committee at the
beginning of 2007 with a very hard task:
Deliver by 2008 a new VPP that will
finally further correct the IMS
typeforming factors in the direction to
encourage fast and fun to sail boats;
full compatibility with ORC club should
still remain and IMS will stay only as
the standard measurement system. The
goal was a new VPP-based rule, and last
November in Estoril ITC delivered. The
result of their hard work was the new
ORC INTERNATIONAL rule, with
certificates issued in the beginning of
January 2008,” says Nazareth.
Do you think ITC has
succeeded in their work?
From a technical
point of view, we believe all the major
issues were solved. Now we have only to
wait for the feed back from the races,”
says Finzi, and stresses the point that
it still is too early to give any
judgment.
Do you believe in a
future with one common international
Grand Prix rule?
We at ORC are fully
convinced that if an International Grand
Prix rule should be adopted it must be
VPP-based and fully transparent for
Designers, Skippers and Owners. We
therefore trust that ORC International
can be the one, says Finzi.
Does such a rule in
your eyes need to be VPP-based?
"Yes, a VPP-based
rule avoids the possibility to design
special boats for just one event, the
so-called “horses for courses”. It must
be clear that the cooperation of very
professional Race Organizers and Race
Committees is very important to avoid
any mistake in the application of any
VPP rule, but when talking of a Grand
Prix rule this should be a standard
requirement, says Nazareth. He
continues:
“ORC VPP rules have a lot of other
scoring options that could be adopted
for lower level races to reduce the
impact on results of such possible
mistakes. Single number time-on-time or
time-on-distance options are fully
available on all certificates.
“It is true that Grand Prix owners and
sailors are asking more and more to have
Grand Prix classes racing in real time,
but a lot of important events, where
different boats are involved and an
overall winner is requested, ORC
INTERNATIONAL is a very good answer to
the request of a very refined Grand Prix
rule.”
Why should sailors
use the ORC rules ORC Club and ORC
International when going racing
worldwide?
“ORC is strongly connected to ISAF that
gives under its regulation a status of
INTERNATIONAL to ORC rating rules based
on their unique characteristics of both
being transparent and scientifically
based. ORC is also the only non-profit
organization that is capable to provide
single Member National Authorities the
capability to run and administer its
rating rules.
“Objective and not subjective,
transparent and not secret, worldwide
and not locally, scientifically based
and not empirical formula based, these
are some of the reasons to choose a
rating system and to be able to race
around the world with one certificate.
“ORC is also convinced about the
possibility of awarding fair handicaps
to every kind of boat, including those
with canting keels,” says Nazareth.
What do these rules
have that make them better than the
other rating rules?
“First of all, the ORC INTERNATIONAL VPP
has a background of more than 20 years
of research activities - like tank
testing, wind tunnel and CFD - that is
currently updated every year. For
example, last year new wind tunnel tests
were conducted at Milan Politecnico
University, and this year will be new
tank tests with new models at Delft
University. Other fundamental
characteristics are that this is a
recognized international rule, it is not
secret, it has a wide variety of scoring
options, and any typeforming is towards
stiff and light boats,” says Nazareth.
Why do you believe
that a VPP based rule is better than an
empirical “secret” rule?
"A secret rule can be subjectively
modified to adjust handicaps without any
possible control. More than this nobody
could doubt that when a rule is defined
“empirically”, either if it is secret or
not, then it has not enough scientific
background as a VPP-based rule,” says
Nazareth. “When you can predict almost
precisely the speed of a boat over a
wide range of wind speeds and angles,
there is no other way to give her a fair
handicap, not even with the more refined
“empirical” rule.”
In the latest
Seahorse Rob Weilland, TP52 class
manager says that a secret rule is an
insult to the intelligence. Do you agree
with this?
“ORC of course is in full agreement with
Rob,” says Finzi.
