FIELD: shipbuilding.
SUBSTANCE: invention relates to the field of shipbuilding of arctic watercrafts with a fore end equipped with a bulb, and is aimed at increasing icebreaking capability thereof. A shape of the fore end is proposed, which is equipped with a bulb with an edge in the diametrical plane in the upper part thereof, inclined forward and crossing the plane of the waterline, wherein the ice waterlines of the bulb in the area of juncture with the fore end are made with a narrowing providing a reduction in the ice resistance, the angles of inclination of the sides of the fore end to the ice waterlines beyond said narrowing are no greater than 80°.
EFFECT: increasing the efficiency of operation of a watercraft due to the improved icebreaking capability thereof.
