Craft which moves on water. The invention relates to the displacement of a craft on water by manual force alone and without the use of oars. Paddles 1 placed under the craft in two boxes are manoeuvred by independent levers 2, and the space requirement is thus limited. The penetration of the water by the craft is controlled with the aid of an inflatable compensator 3. Among the applications of the invention, mention can be made of aquatic leisure activities and muscle-development. <IMAGE>
