These are beispielswei ⁇ se needed for maneuvering a ship in the harbor or for the exact positioning of a ship on the high seas. If such a jet propulsion system is used only for propulsion of the ship transversely to the direction of travel, it is referred to in the most general form as a "transverse jet propulsion” or “transverse thruster”.
