Interpretation de la règle de classe des 10r
Posté : jeu. 12 sept. 2019, 07:26
Bonjour à tous,
Voici une copie de la lettre que Robert GRUBISA, président du Comité Technique de l'IRSA a envoyé aux représentant de tous les pays membres de l'IRSA :
A Clearer Approach On Current Practices And Interpretations Of
Part Of The 10R Class Rules.
IRSA Technical Committee
Letter to the IRSA Members.
September, 2019
Please respond to this letter by 30 September 2019
10R Class Rules are ‘open’ rules with great freedom to develop, design and construct. However,
there is a current approach to the rules that needs to be clearer, so that everyone has the same
opportunity to sail within the same accepted rules.
To explain this situation, consider this approach:.
Scenario: “A week before the event a skipper sees the 8 day forecast and knows it will be blowing 20-
30 knots for the day of the race. He knows he will not need his No 1 or No 2 rigs in this wind and,
knowing his heaviest rig (the No 2) is at least 100 grams heavier than his lower rigs, he makes himself
a ballast that is 100 grams heavier.”
Rule interpretation
According to the current 2018 Edition of the International 10R Class Rule this scenario is not allowed:
“C.4.4 LIMITATIONS
(a) The boat shall sail with the hull, hull appendages and ballast used at the certification control
relating to the certificate used for the event.”
On the other hand, according to the C.6.1 of the 2002 Edition of the 10R Class Rule it only requires
the same hull appendages to be used during an event (except where there was loss or damage).
Class Rule E.1.1 required the hull appendages to comply with the current class rules. So, there was
no requirement for the boat to use the same hull appendages as at certification control.
As stated, 10R Class Rules are ‘open’ rules with great freedom to develop, design and construct. So
reverting to the previous "freedom" may make life easier to all involved. Obviously this approach has
an impact on the cost of maintaining a competitive 10R because of allowing multiple foils/ballast
combinations.
On the other hand, it is possible under current rules to have multiple certificates so an owner may
have more valid certificates for each of the foils/ballast combinations causing a problem as to how
to "connect" each configuration with the relevant certificate.
So in summary,
Do you agree to the IRSA Technical Committee amending the current wording of the International
10R Class Rules in order to allow the use of any hull appendages and ballast providing that the
limitations relating to the certificate used for the event are complied with. Final technically sound
wording of the amended class rule(s) to be provided by IRSA TC.
Please feel free to ask questions or suggest alternative approaches to this issue.
Regards,
Robert Grubiša,
(IRSA TC Chairman)
