Counter sterns - measurement manual error

UPDATE 21 June 2010: This has now been corrected and the updated version can be downloaded from the Technical section of this website.
Please note that there is an error in the latest IRC measurement manual regarding the measurement of ‘y' for counter stern boats.
On page 14 the drawing for counter sterns should be the same as in the IRC Yearbook, as shown HERE (PDF)
We apologise for any confusion caused.

IRC 2011 - Composite rigging

PRESS RELEASE
IRC 2011
Composite Standing Rigging
At a recent meeting of the IRC Technical Committee, the subject of the rating cost of composite standing rigging was discussed.
The Committee noted that the technology of composite standing rigging has matured significantly in recent years to the extent that it is now becoming close to mainstream.
There is now evidence that composite standing rigging has a life expectancy at least that of steel rod rigging.
In parallel, the cost of composite standing rigging has fallen to the extent that some brands are now available at costs only a little higher than the equivalent steel rod rigging.
Composite standing rigging is also now beginning to become available as a standard option from production boat builders.
Noting all of the above, the Committee has concluded that the rating cost of composite standing rigging will be reduced with effect from 1st January 2011 (1st June 2011 in IRC southern hemisphere countries). This notice has been issued now to enable owners considering either new boats or modifications to their existing boats to plan accordingly.
The exact effects on TCC are not yet available. The Committee's intention however is that the effects should in future be broadly neutral in terms of speed versus rating. The effect of composite standing rigging will also continue to vary from boat to boat.

Gréement dormant en matériau composite
Lors de la réunion récente du Comité Technique IRC, la question de l'impact du gréement dormant en matériau composite sur le TCC a été discutée.
Le Comité a constaté que la technologie de ce type de gréement a progressé de manière significative au cours des dernières années et que son utilisation est aujourd'hui courante.
Il est maintenant prouvé que l'espérance de vie d'un gréement dormant en matériau composite est au moins égale à celle d'un gréement en rod.
Parallèlement, le coût d'un gréement dormant en matériau composite a baissé au point que certains fabricants proposent des produits à un prix à peine plus élevé que leur équivalent en rod.
De plus, le gréement dormant en matériau composite est proposé en version standard par certains fabricants de bateaux de production.
Considérant ce qui précède, le Comité en a conclu que l'impact sur le TCC d'un gréement dormant en matériau composite serait réduit à partir du 1er janvier 2011 (1er juin 2011 pour l'Hémisphère Sud). Cette note est publiée dès à présent pour permettre aux propriétaires de prendre cet élément en considération dans leur projet d'achat de nouveau bateau ou de modification de leur bateau actuel.
Le calcul de l'impact exact sur le TCC n'est pas encore finalisé. Néanmoins, l'objectif du Comité est que l'impact soit neutre en termes de vitesse par rapport au rating. Cet impact continuera à varier d'un type de bateau à un autre.
