KONA CLASS RULES
INTRODUCTION
The main objectives of the Kona Class are to promote inexpensive and easy one design racing with emphasis on tactics rather than equipment to increase speed.
Kona hulls, hull accessories, and sails shall be built by manufacturers appointed by Exocet/Flying Fish. Said components are measurement/manufacturing controlled. Rig components such as mast, boom, mast extension and mast base are optional, but limited as outlined in Section C 10 herein.
After Kona hulls, accessories, rigs and sails have left the manufacturers, they may only be altered to the extent permitted in Section D of the class rules.
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.
