The Kona Gold Cup is an annual International event – emphasizing
on fair one design racing at all skill levels – as well as social gatherings and comradery in true “Konadian” spirit. The prestigious cup itself is perpetual, which means that it is presented every year and with the names of previous over-all winners engraved on it.

  • KONA 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 hulls, hull appendages, and sails shall only be manufactured by Exocet/Flying Fish or their appointed manufacturers. Such equipment is required to comply with the Kona One Design Building Specification and is subj ect to an ISAF approved manufacturing control system.

    After Kona 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 Class Rules proper begin on the next page.
