A windsurfing board formed by a base that slides over the water and having a folding joint, with a mast, a sail and a boom with two lateral branches, some facing compartments with cover for concealed wheels, and another compartment with a watertight cover for documentation. The base has a rudder and/or lower wing with a moveable part activated by turning grips located on the boom. There are also some rollers for the two cables holding the harness of the windsurfer and some floats. On the lower edge of the sail is attached an addition whose lower edge is fixed to a support that turns with the foot of the mast. The mast has some limiting stops in its downward movement and is formed in three removable parts. The sail has some cross-pieces for stretching its free edge.
