The invention relates to an ice-negotiating vessel with an ice nozzle unit with a pump which is connected on the suction side to a suction funnel and on the pressure side leads into a mixing nozzle with a feed in which a pressurized-water jet or compressed air in the form of individual compressed-air blasts is directed into the interior space of the suction funnel in order to avoid the formation of ice in the suction-funnel interior space adjacent to the sea-water inlet openings. <IMAGE>
