(57) Abstract: The invention relates to sports shipbuilding and can be used as flotation devices for entertainment, tourism and water sports. The Board contains a buoyancy and a crossbeam, which is lastby mover. Aft buoyancy made the speaker back narrow keel. The transverse beam is fixed on. the end of the keel. This is an opportunity for active recreation, entertainment, tourism, sports on the water with the development of muscular strength and agility, with the possibility of movement regardless of the presence of wind. 2 Il. The invention relates to the field of sports shipbuilding and can be used as a means for entertainment, tourism and water sports. Famous windsurfer Board for skating, containing buoyancy and propulsion in the form of a sail. The lack of windsurfer is that in small areas in the most favourable for water leisure time the wind does not always there and sail propulsion is idle. In addition, for the physical development of the athlete windsurfer does not generate sufficient dynamic muscle loads. It is also known craft for fun and sport is ΓΌ mounted on the cross beam. Transverse beam on which is mounted lastby mover connected to the stern narrow boats stand. The disadvantage of this invention is that when the real dimensions of the apparatus with a muscular drive impossible to obtain a sufficiently high velocity flappers and, accordingly, the hydrodynamic forces for movement of the device. The claimed invention is directed to the solution of active recreation, entertainment, tourism, sports on the water with the development of muscular strength and agility, with the possibility of movement regardless of the presence of the wind. The technical result of the claimed invention is the ability to provide propulsion great velocity and, accordingly, large hydrodynamic forces used to move the claimed Board. This result is achieved by the fact that the Board containing the buoyancy and crossmember, which is lastby the thruster, aft buoyancy made the speaker back narrow keel and transverse beam is mounted at the end of the keel. When the keel buoyancy acting back in the aft buoyancy narrow keel tells fixed on consolename on the cross beam lastowka the propulsion flow of fluid with a sufficiently high speed, at which efficiently generate large hydrodynamic forces. The horizontal projection of the hydrodynamic forces is the driving force of the claimed device, and the larger the driving force, the higher the speed of the device. This speaker back narrow keel is geometric amplifier linear velocity of the hull buoyancy transmitted lastowka the mover, and ensures the achievement of a technical result. In addition, the high velocity flow listovogo mover can significantly reduce its area and thereby reduce the power loss by friction. This contributes to the execution of a prominent keel narrow. In Fig. 1 shows the form boards "Le" on the side, Fig. 2 - in the plan. Board "Le" contains buoyancy 1, aft which made the speaker back narrow fin 2. The transverse beam 3 with consoles 4 and 5 is mounted at the end of the fin 2. Lastby mover 6 is mounted on the cross beam 3. Board "Yul" moves as follows. On buoyancy 1 is the athlete so that one leg was in front of the other. Alternately shifting body weight from one foot to the other, the athlete raises the keel rocking at the lucesti 1 and standing on her athlete. Fluctuations of the transverse beam 3 transmitted installed on it lastowka the propeller 6. As a result of fluctuations listovogo thruster 6 it occurs wrap surrounding liquid and the generation of hydrodynamic forces. The hydrodynamic force can be decomposed into alternating vertical and repeated horizontal components. The vertical component has a resistance to the action of the athlete, and the horizontal component provides the device movement forward. The stop device is its braking, which the athlete must move the weight of the body to create a constant pitch device on the stern. Boards containing buoyancy and crossmember, which is lastby mover, characterized in that the aft buoyancy made the speaker back narrow keel and transverse beam is mounted at the end of the keel.
