Abstract: An autonomous water vehicle for moving above the water surface, part of the device being under water and part being lifted above the water surface. The water vehicle includes an underwater propulsion module, an upper platform and a vertical support, a power source and an electronic control unit. The propulsion module has a housing in which at least two propeller groups are preferably mounted, including electric motors and water screw propellers with two to five blades, such as the propeller groups are arranged symmetrically with respect to the central vertical axis of the housing and are designed to generate vertical thrust for lifting the upper platform plus maximum payload above the water surface. The rotational axes of the propeller groups are arranged vertically or at an angle to the central vertical axis of the housing.
