Class rules

INTRODUCTION

The Kona Class is devoted to the development of inexpensive one design racing, with an easy format where the emphasis is on tactics rather than equipment.

The Kona ONE hulls, hull appendages, and sails shall only be manufactured by Kona Windsurfing AB or their appointed manufacturers. Such equipment is required to comply with the Kona One Design Building Specification and is subject to an ISAF approved manufacturing control system.

After Kona ONE hulls, hull appendages, rigs and sails have left the manufacturer, they may only be altered to the extent permitted in Section C of these class rules.

Rules regulating the use of equipment during a race are contained in Section C of these class rules, in the Equipment Rules of Sailing Part I and in the Racing Rules of Sailing.

This introduction only provides an informal background and the Kona ONE Class Rules proper begin on the next page.
