FIELD: transport.
SUBSTANCE: invention relates to ship building, particularly to ice breaker design and operation. Ice breaker has hull with bow representing a trimaran and consisting of the main hull inherent in ice breakers, and two side hulls. Lower part of bow end of the main hull is located below construction waterline. Side hulls are arranged on platform mounted atop the main hull and represent lateral ice breaking reamers extending forward and downward. Lateral edge of said reamers smoothly changes into the surface of freeboard in rear part, while, in front part, it is vertically flat. Lower edge of ice breaking reamers is located above construction waterline.
EFFECT: expanded performances, better maneuverability.
