    Abstract: A leisure boat is provided in a round form having a diameter of about 1 to 2 meters, and includes propeller means provided at a position closer to its bow from the center of the boat and the bow and having a mechanism for changing its driving direction and sensor means provided on the outside of the boat for sensing external force. The sensor means is so connected to the propeller means that when the boat comes in contact or collision with another boat, etc., the sensor means detects the resulting external force to transmit it to the propeller means, thereby changing its driving direction.

    Abstract: An arrangement including a gearwheel connected to the propulsion unit, a steering electric motor operatively connected to the gearwheel and controlled by a drive, a force transmission arrangement including a clutch between the gearwheel and the steering electric motor, and a measurement unit for measuring rotational motion positioned at each side of the clutch. The steering electric motor is arranged to rotate the gearwheel and thereby also the propulsion unit. A difference in the output signals of the two measuring units indicating slipping of the clutch is detected. The steering electric motor is controlled to at least reduce the difference in the output signals when the difference exceeds a predetermined threshold.

    Abstract: A vessel and a method in a vessel with a hull and a propulsion unit. The propulsion unit comprises a hollow strut rotatably attached to the hull of the vessel, a propeller shaft having an axial centre line and being positioned and supported in the lower portion of the strut with bearings, a propeller being attached to at least one end of the propeller shaft protruding from the lower portion of the strut, and an electric motor driving the propeller shaft. An additional support arrangement is positioned at least in one end portion of the propeller shaft axially outwards from the bearings. The support arrangement comprises a first support surface formed in connection with the propeller shaft and a second support surface mating with the first support surface and being formed in connection with the lower portion of the strut. The second support surface is positioned at a predetermined distance from the first support surface so that a slot is formed between the first support surface and the second support surface facing towards each other. The being of the propeller shaft due to external loads acting on the propeller is restricted to a predetermined maximum value with the support surfaces.

    Abstract: A propulsion unit is disclosed, which can include a casing, a shaft, a propeller, an annular housing and a rim drive electric motor. The casing can be rotatably supported at a hull of a vessel. The shaft can be rotatably supported with bearings within a lower portion of the casing. A propeller can be attached to an outer end of the shaft protruding from the lower portion of the casing. The annular housing can surround an outer perimeter of the propeller and can form a duct for water flowing through the interior of the annular housing. The rim drive electric motor can include a rotor rim provided on an outer perimeter of the propeller and a stator provided within the annular housing. Oil lubricated roller bearings can be used on the shaft within the casing. The axial length of the propulsion unit can be short.

    Abstract: A boat drive for a boat having a boat hull with a bottom. The boat drive includes an underwater pod; an electric motor disposed in the underwater pod, the electric motor driving, via a drive shaft, a propeller attached to the underwater pod; and an electrical supply line for supplying energy to the electric motor. The boat drive further includes an inner tube connected to the underwater pod and displaceably disposed in an outer tube, wherein the electrical supply line is routed through the inner tube. The boat drive further includes a mounting body attachable to the bottom of the boat hull, wherein the outer tube is passed through the mounting body. At least one annular sealing element is disposed between the inner and outer tubes, wherein the at least one annular sealing element seals the inner tube and the outer tube in a radial direction relative to the longitudinal axis of the inner tube.
