INTRODUCTION

This introduction only provides an informal background and the International J/70 Class Rules proper begin on the next page. The J/70 Class has been created as a strict one-design Class where the true test when racing is between crews and not boats and equipment. The fundamental objective of these class rules is to ensure that this concept is maintained. J/70 hulls, hull appendages and rigs shall be manufacturer controlled and shall only be produced by a manufacturer licensed by J Boats, Inc. Equipment is built in accordance with the J/70 Building Specification and Configuration Manual. These parts having left the manufacturer may only be altered to the extent permitted in Section C of the class rules. J/70 sails are measurement controlled to control all the primary dimensions but may be made by any manufacturer. In order to confirm compliance with the class rules sails are required to be certified by an official measurer or by a manufacturer licensed under World Sailing In House Certification. These parts may only be altered to the extent permitted in Section C of the class rules after certification control has been performed. 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.
