This rule applies to monohull sailing yachts, with the aim of racing offshore in real time.
A monohull is a boat with a single flotation plane at rest or under sail, whose hull depth in any transversal section shall not decrease towards the centre-line.
Current ISAF rules (RCV, ERS & OSR) apply
The Classe 9.50 monohull Class Rules are the open type set out in Paragraph C.3.3 of the ERS (Rules of Equipment for Sailing boats), meaning that anything that is not expressly forbidden, limited or enforced, is authorized.
The Class official language is French.
The Class 9.50 monohulls are aimed to coastal semi-offshore and offshore racing.
Skippers should note that their piloting is not without danger under certain sailing conditions, and that the decision to race is theirs alone, to enforce Article 4 of the RRS.
The safety of the boat and its crew is the inalienable responsibility of the sole owner, or its skipper, which must ensure that the yacht is in a good condition all over, perfectly seaworthy, and that it is manoeuvred by an experienced crew, which has taken the appropriate training and is physically capable of confronting the bad weather.
To enforce article 3 (c) of the RRS and whatever the circumstances of the possible accident, no legal responsibility can be sought from whatever party as regards the ISAF, the ANM (FFVoile), Classe 9.50, or an official measurer of the present rules.
The class must respect the conditions set out in Category C of the Publicity Code of the ISAF Ruling (Chapter IV; 20).
The production 9.50s and prototypes will share a common ranking.
Routing is forbidden while racing.
The Class Association is the body warranting the class rules and their eventual evolution. The Class rule of the Classe 9.50 is applicable from January, 1st of each year to all the 9.50 yachts.
Eventually, incompliance to the rules will be studied specifically one by one depending on the official publishing date of these rules and on the design or building date of the concerned element.
The General Assembly of the Class is the only authority habilitated to modify and construe the class rules. The official measurer is responsible for the application of the rules and can insist on a demonstration if necessary.
