A vehicle comprises a carrying board structure of a flat elongated configuration, means being provided on one face of said board structure for releasably mounting a sail-carrying mast structure, and two longitudinally spaced axle supporting means being resiliently mounted on the opposite face of said board structure. Dead axles are rigidly supported by said axle supporting means, said axles extending beyond the lateral edges of said board structure. The opposite ends of each axle comprise means for mounting vehicle travelling means having low frictional contact surfaces. In an embodiment, said travelling means are wheels provided with inflatable tires, said wheels having an outer diameter of about 30 cm.
