ABSTRACT OF THE DISCLOSURE An ice-breaking apparatus for use in ships and barges operating in icy waters, including nozzles for jetting high pressure fluid, is disclosed. By impinging force or cavitation caused by the high pressure fluid jetted from the nozzles, grooves or cracks are formed in an ice floe, and then, the ice floe is broken at these grooves or cracks by the hull. This ice-breaking apparatus facilitates breakage of ice floes or the like, and when this ice-breaking apparatus is attached, ships or barges operating in icy waters can be built without increasing their dimensions or propulsion powers, particularly useful for navigation in icy waters.
