Abstract
A windsurfing board with a hull, a mast and a wishbone or other spar for winging out the sail has side fin plates with lower stabilizing faces and an adjustment system for steplessly changing the level of such fin plates, or only producing two positions of adjustment so that such fin plates are under or clear of the water. The lower position under the water is designed for producing better planing properties of the windsurfer while the top position is used for sailing under only a light wind.
