Rules & Regulations/Registration System



An ISAF Approved Series Production board or board range* is a mass produced board or board range, made in a production run of not less than 50 Slalom/Speed or 50 Freewave units per board in the range. Each board in the range must be produced from identical female moulds using the same construction specification.

*A range of boards may consist of up to 5 sizes of board with identical design purpose but varying dimensions making them suitable for different wind/wave conditions or crew weight.

These moulds (sets) shall have been inspected (Part II registration), together with a board from the production run, prior to the board being added to the approved list for International, Continental or World Championships. Boards for which ISAF Part I registration has been applied but have not yet passed the inspection, are eligible for National Racing only.

Speed/Slalom or Freewave boards can be used in international competition 30 days after the completion of the registration process Part 2 and ISAF receiving the appropriate fee. Boards not meeting this requirement or minimum production numbers will be ineligible for use in World or continental Championships.

This shall be done by way of individual board serial numbers and copies of shipping documents from the manufacturer being sent to the ISAF Secretariat.

Only a board 'Part II' registered by ISAF may race in Funboard Class Windsurfing Class international events.
