Vaurien Class Rules

The most recent version of the International Vaurien Class Rules is officially published on the class rules subsection of the ISAF website.

World Sailing plaque

Every Vaurien gets the blue World Sailing (WS) plaque with its sail number during the initial measurement procedure. A boat may not leave the builder’s facilities without it. The WS plaque shows that the boat has been measured, the building fee, and the designers royalties have been payed. According to the Vaurien Class Rules, the WS plaque shall be fixed to the starboard inside face of the transom. However, on some boats, it is fixed to the port side or to the starboard side of the main bulkhead (behind the spinnaker bag).

If your WS plaque is lost, damaged or illegible, a replacement can be acquired through IVCA or your National Vaurien Class Association. The costs are approx. 43 € plus postage. The replacement plaque will be sent to your National Vaurien Class Association, who will find a measurer to fix the replacement to your boat.
