An arrangement (10) for the reduction of wave-induced motions of a vessel having at least in part water jet propulsion is taught. The water jet engine comprises a nozzle (1) capable of being rotated about a substantially vertical axis (2), said nozzle (1) having an inlet end for the water flow and an outlet opening (12) which forms the water jet that generates the reaction force for propulsion of the vessel. In addition, the nozzle is capable of being pivoted about a substantially horizontal axis (5), said rotatability in the horizontal plane about the vertical axis (2) being for the purposes of navigation, whereas the pivotability in the vertical plane about the horizontal axis (5) is to counter or reduce the said wave-induced motions of the vessel. |
