  • Patent number: 10358192
    Abstract: The object of the invention is an inflatable watercraft (1) (SUP—stand up paddling) with an embedded drive and having a specially shaped recess in the center, preferably in the center of gravity of the watercraft (1), into which a housing (2, 2?) of a drive assembly is inserted before the watercraft is filled with air. While the watercraft (1) is filled with air, the air pressure firmly fixes the housing (2, 2?) of the drive assembly to a proper position. The housing (2, 2?) accommodates the drive assembly that comprises a storage battery (4), an electric motor (5), a compressor (3) and an electronic circuit (8), wherein the drive assembly is provided with a flow-through channel (6), in which a drive screw (7) is arranged, and both the input and the output sides of the flow-through channel (6) are protected by grates.
