  • the floating body 2a consists of several vorverbundenen floating elements, such as two or three floating elements, which may be together or possibly hinged on possibly parallel aligned joints, to be easier to transport, as is known in the practice.
  • the propulsion devices 4 could also be formed by only one pump jet or contain only one pump jet, in which case direction and / or orientation stabilization devices, such as a keel or a fin or a plurality of them, may advantageously be combined in order to be able to ensure directional propulsion , It is also possible to provide a drive, which can be controlled in particular with respect to the drive power, in terms of alignment with another drive of a different design even with a pump jet which can be controlled by 360 °. In the simplest form, however, a 360 ° controllable pump jet or other suitable drive alone may be sufficient to ensure targeted and directional propulsion.

Thereafter, the connection means 8 can be released from the power connection means 7, and the power supply unit 11 can be removed from the floating member 3 of the floating body 2a.
  • the power supply unit 11 can be easily driven on land. Otherwise, the power supply unit 11 can be reloaded onto another floating body or a boat and brought to land, for example, where it is available, in particular, for supplying energy to further floating bodies. Also, e.g. with a helicopter, the power supply unit 11 can be picked up by the float 2a.
  • the mobility of the power supply unit 11 thus leads on the one hand to the advantage that a plurality of floating bodies are not required for a plurality of power supply units, but at minimum a power supply unit is sufficient for a plurality of floats, and also leads to the advantage that the entire surface of the Float 2a or pontoons 1 is available as a usable area and not even a partial area is lost by the power supply unit. All this is achieved in that the power supply unit, in particular the generator set, only temporarily for a shunting or a Fähr congress the present a float 2 a on the floating element 3 is arranged.
