  • This angle is very advantageous especially with regard to the radiation.
  • the side surfaces 12a-d are all arranged such that they do not run parallel to the ground or the water surface at least in the rest position of the AUV 10. In other words, this means that the surfaces are arranged at an angle.

  • the low payloads allow further advantages, namely that a variety of control mechanisms can be effectively integrated in addition to the conventional control over rudders (which are flowed through the vehicle movement):
  • a control in the sense of maneuvering for example, by sliding trim, for example via weights (in the keel), which are movable by means of toothed belts, or by pumping ballast tanks, can be realized.
