Notice 2018/01

With effect from 23 March 2018, in IRC 2017 and 2018 Rules, insert new rule modifying RRS49.2:

Add IRC rule 22.6:

22.6 Crew Position
22.6.1 RRS 49.2 is modified by deleting “sitting on the deck” in the second sentence.

Reason
It is not unusual for crew sitting on the rail to be supported only at their upper legs when hiking facing outboard. The term “sitting on the deck” is difficult to define and to avoid unnecessary and difficult protests a simple and effective solution is to remove this requirement from RRS 49.2 while maintaining the original intention of:
a. When there are two lifelines, competitor facing outboard with their waist inside the lower lifeline may have the upper part of his body outside the upper lifeline.
b. Lifelines shall be taut (by the OSR definition)

The RRS 86.1(c) permits Class Rules to change RRS 49.

The IRC 2017 Rule is included for those countries still racing under IRC 2017 until 31st May 2018.

Note IRC 2018/01
RCV 49.2 – Positions de l’équipage, filières

Avec effet le 23 mars 2018 dans les Règles IRC 2017 et IRC 2018, la règle suivante est insérée en modification de la RCV 49.2 :

Ajouter la règle IRC 22.6 :

22.6 Position de l’Equipage
22.6.1 La RCV 49.2 est modifiée par retrait de l’expression « assis sur le pont » dans le second paragraphe.

Raison :
Il n’est pas rare que l’ équipage, assis sur le rail, s’appuie uniquement sur la partie arrière haute des jambes lorsqu’il se met en place, face à l’extérieur.
Le terme «assis sur le pont» est difficile à définir et, pour éviter les protestations inutiles et difficiles, une solution simple et efficace consiste à supprimer cette exigence de la RCV 49.2 tout en conservant l'intention initiale de:
a. En cas de filières haute et basse, le compétiteur face à l’extérieur avec la taille à l’intérieur de la filière basse peut avoir la partie supérieure du corps à l’extérieur de la filière haute.
b. Les filières doivent être tendues (Ref : Définition dans les Règles de Sécurité Offshore)

La RCV 86.1(c) autorise les Règles de Classe à modifier la RCV 49.

La Règle IRC 2017 est modifiée pour les pays qui régatent selon cette Règle jusqu’au 31 mai 2018.

Comité Technique IRC
23 mars 2018

The following IRC Rule changes were approved by Congress in October 2017:

• In Rule 21.5 the ‘default’ values for mainsail widths have been deleted as this was inconsistent with the Rule on headsails.
• The Dayboat Definition and Rule 24 have been deleted, as IRC cannot and should not judge OSR compliance.
• The final sentence of Rule 8.2.1 has been corrected to reflect the intention of the Rule on short-handed certificates.
Rule 13.2 has been changed in accordance with IRC Notice 2017-01, relating to sail measurement batten length.
Rule 17.1 now clarifies that cushions are only relevant to measurement condition if carried while racing.
Rules 21.2.1 (Rig Factor) and 22.2.1 (Hull Factor) have been updated to reflect actual practice.
• Definitions have been added for the measurement of lifting foils, to reflect the increased use of these and development of how they are rated.
• Other changes are: deletion of the IRC Headsail Head Point definition as this is now identically defined in ERS; a correction to the Advertising Code reference in Rule 26.1; and confirmation that in Southern Hemisphere countries the new IRC Rule does not come into force until June 2018 (the exception is Rule 13.2 as Notice 2017-01 applied with immediate effect from May 2017).
