<p>The invention relates to an electric motor-driven water craft comprising a fuselage (10), on which the user can at least partially lie or stand. Said fuselage (10) comprises a flow channel with a screw (2) that is driven by an electric motor (3) and contains the electric motor (3) and batteries (5, 6), in addition to a control device (4) for the electric motor and the screw (2), said items being housed at least partially in the flow channel (8). The aim of the invention is to maintain a higher power for motor-driven water craft of this type. To achieve this, the batteries (5, 6) are located in a water-tight housing (9) and at least some sections of said batteries are in thermally conductive contact with the housing (9), the housing (9) consists at least partially of a thermally conductive material and/or the electric motor (3) is an internal-rotor motor, the stator (21) is in thermally conductive contact with a housing (35) of the electric motor (3) by means of a heat conducting unit (22), at least part of the region of the housing (35) that is assigned to the heat conducting unit (22) consists of a thermally conductive material and the housing (35) is located at least partially in the flow channel (8).</p> |
