Definitions

  • the present invention relates to a motorized boat or vessel.
  • the present invention is advantageously used in the nautical sector, preferably for sport or pleasure watercraft, to which the following description will make explicit reference without losing its generality, in order to allow easy use of the vessel with safe hauling and launching operations, without interference from the drive unit with the lines of the hull and deck of the vessel.
  • boats are universally known and used, such as inflatable boats (with or without rigid hulls) or boats, of generally reduced dimensions, equipped with outboard motorization units applied and mounted on the stern mirrors of the boats themselves.
  • a known outboard motorization unit is of the type comprising an internal combustion engine (diesel or petrol) or an electric propulsion engine, which is fixed in a removable way, for example by means of suitable screw clamps, to the wall of the rigid transom of the vessel to carry out the propulsive advancement of the vessel at the same time defining a rotating rudder steering organ of the vessel itself.
  • an internal combustion engine diesel or petrol
  • an electric propulsion engine which is fixed in a removable way, for example by means of suitable screw clamps, to the wall of the rigid transom of the vessel to carry out the propulsive advancement of the vessel at the same time defining a rotating rudder steering organ of the vessel itself.
  • This motor is normally provided mobile mounted around an axis transversal to the longitudinal axis of the vessel, to be moved between an operating position with its own rotatable foot equipped with a propulsive propeller, vertically immersed in the water below the waterline, at the in order to allow the subsequent advancement and controlled steering of the vessel, and an inactive raised position of rest, by manually rotating the engine itself parallel to the aforementioned transom and with the foot and propeller out of the water, usable and used during operations launching and hauling of the vessel, and / or in the phases of storage with maintenance of the same engine.
  • the main purpose of the invention in question is therefore to eliminate the significant drawback described above.
  • an object of the present invention is that of realizing a motorized watercraft or vessel, preferably sport or pleasure watercraft, whose motorization unit is always installed, well fixed and at the same time is easy and quick to move in order to position the same motorization so as not to interfere with hull and deck lines.
  • Another purpose of the present invention is to create a motorization unit for a watercraft or vessel which, during the launching and hauling operations of the vessel itself, eliminates the possibility of causing harm to the safety of persons or damage to the vessel itself.
  • a further object of the present invention is that of realizing a motorization unit for boats which is not bulky.
  • N globally and schematically indicates a generic vessel, boat or watercraft (in the non-limiting example shown, a rubber dinghy) provided with hull S and an engine unit M, a propulsion body 1 having a foot 2 and supporting a propeller 3 adapted to be fixed outboard on the rigid transom 4 of the hull S of the vessel N, in order to define a propulsion element and a vertically orientable (tilting) rudder for steering the same vessel N ( Figure 4 ).
  • a generic vessel, boat or watercraft in the non-limiting example shown, a rubber dinghy
  • a propulsion body 1 having a foot 2 and supporting a propeller 3 adapted to be fixed outboard on the rigid transom 4 of the hull S of the vessel N, in order to define a propulsion element and a vertically orientable (tilting) rudder for steering the same vessel N ( Figure 4 ).
  • the body 1 directly mounts a propulsion motor M1 also mounted outboard with respect to the vessel N, while according to a variant not shown, the body 1 is directly and mechanically connected to a propulsion motor which it is instead foreseen mounted inboard in the vessel N.
  • the body 1 is mounted and fixed on the aforementioned transom 4 so that it is rotatable (arrows F in Figure 2 ) around a K axis coaxial to the longitudinal Z axis of the hull S of the vessel N and transversely with respect to the plane of the transom 4, to move, under the thrust of known actuator means and not shown or manually, between an operating position PO with its own foot 2 and relative propeller 3 immersed in the water below the waterline L (bottom line) of the hull S ( Figures 1 and 2 ), in order to allow a controlled advancement and steering of the vessel N, and an inactive position at rest PR ( Figure 3 ) of the body 1 of propulsion, in correspondence with which the body 1 itself is arranged with the aforementioned foot 2 and propeller 3 at least partially outside the water, i.e. at least partially above the aforementioned waterline L.
  • the motor M1 is an electric motor mounted on a special fixing hole 5 present on the transom 4 so as to rotate around the aforementioned K axis with the aid of bearing means (not shown) applied to the hole 5.
