INTRODUCTION

The object of the International Funboard Class Rules is to establish the Class as one in which many different types of production sailboards, which are available internationally, can compete. Freedom for manufacturers to develop boards is encouraged within certain restraints.
Funboard hulls, hull appendages, rigs and sails are measurement/manufacturing controlled.
Funboard Hulls shall only be manufactured by ISAF registered manufacturers. Equipment is subject to an ISAF approved manufacturing control system.
Funboard hulls may, after having left the manufacturer, 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.
This introduction only provides an informal background and the International Funboard Class Association Class Rules proper begin on the next page.
