A motorized watercraft with a hull of the craft on which a user lies prone, at least partially, or stands up, with a flow channel extending in the hull of the craft with an electric motor-driven water screw. The electric motor and the batteries, as well as the control device for the electric motor and the water screw are housed, at least partially, in the flow channel in the hull of the craft. A clear increase in efficiency can be attained in connection with the motorized watercraft if a flow stator is arranged in the flow channel of the water screw, upstream, or preferably downstream, in the flow direction, which at least partially straightens the rotating water flow generated in the flow channel.
