Please submit any comments to the Chairman by 31 May 2018.
Supernova Class Rules Version 2.9 Sept 2017
1.1. The Supernova is a strict One-Design hull single-handed hiking dinghy designed by Mark Giles to promote close competitive racing. It was designed using the fundamental principle that the racing results should depend solely on the attributes and skills of the crew.
1.2. The Supernova was originally built by Mark Giles (Sail Nos: 357 – 582). It is now built exclusively by Hartley Boats who have re-developed the internal layout (The Supernova MKII, Sail Nos 1000 - ) to enhance comfort and modernise the boat. The construction of the boat has also been modernised and the core hull is now (Sail Nos: 1033 - )built using epoxy.
2. One Design nature of the Class
2.1. To be a Supernova, the boat and its “Major components” (see section 5) must comply with the Class Rules.
2.2. All major components are strict one design, originating from the builder, who may themselves utilise components providers from other suppliers for some parts.
2.3. The builder may from time to time have to vary the specification of the major components. Should this be necessary this is done in consultation with the Class Association.
2.4. Any alteration to the major components as supplied by the builder shall be prohibited, except as specifically authorised by these rules.
2.5. Alterations can be made to any component that is not listed as Major.
3. Application of the Class Rules
3.1. The Class Rules may be amended periodically by the Supernova Class Association in consultation with the Builder.
3.2. Interpretations of the Class Rules shall be made by the Class Association Committee. Interpretations made by the Committee shall rank as Class rules until superseded by a Class Rule change. All interpretations shall be published as soon as is practical.
3.3. The Class Association Committee may decide to outlaw, at any time items that, while apparently permitted under the rules it deems detrimental to the class. This might be due to the cost to other owners to “keep up”, or to prevent unfair advantage. Please see Appendix 1 for rulings implemented under this clause. (This clause is used carefully , as it not the intention to prevent minor developments which might increase speed/comfort, provided that costs are low enough to permit other owners to follow.)
4. Class Association membership
4.1. To be eligible to race in Class Traveller events, the helm shall be a member of the Supernova Class Association or be an existing member of the club at which the event is being held.
