The intention of these rules is to ensure that the boats are as alike as possible in all respects affecting performance. Everything that is not actually stated as permitted or optional shall be prohibited. Hulls, Hull Appendages, Rigs and Sails are measurement controlled. Variations are  permitted within the specifications in “Section F – Rig” and “Section G – Sails”. Tornado hulls and masts shall be manufactured for sale by licensed manufacturers.  A Tornado shall be equipped in accordance with “Section C- Conditions for Racing” of these class rules. Owners and crews should be aware that compliance with rules in Section C is NOT checked as part of the hull and mast certification process. Rules regulating the use of equipment during a race are contained in Section C of these class rules, in ERS Part I and in the Racing Rules of Sailing. This introduction only provides an informal background and the International Tornado Class Rules proper begin on the next page.  2008 TORNADO CLASS RULES 3   PART I – ADMINISTRATION SECTION A – GENERAL A.1 LANGUAGE A.1.1 The official language of the class is English and in case of dispute over trans-lation the English text shall prevail.
