FIELD: water transport; resonance ice breaking by means of hovercraft. SUBSTANCE: method includes correction of resonance speed of hovercraft by maximum magnitude of trim aft; accurate magnitude of required speed of ship at initial moment of resonance breaking of ice is determined and is maintained by maximum sound signal transmitted from ice during its breaking through sound vibration receiver and separated from sound signal created by noise of operation of hovercraft. EFFECT: enhanced efficiency. 2 dwg
