ICE-FISHING VESSEL Russian patent published in 2020 - IPC B63B1/06 B63B35/08 

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding, relates to the year-round operation of a fishing vessel both in heavy ice conditions and in conditions of intense sea waves. Disclosed is a fishing vessel for operation in areas of northern seas, comprising a body with ice outlines and ice reinforcement, superstructure, nose end formed by stem with surfaces of beads connected on it above waterline level, conjugated below waterline level with bulb surface, containing in its upper part rib formed in diametral plane (DP) of vessel, having slope downwards from plane of waterline, and motor is an office complex. Stem in the above-water part is made with rounding along the DP and with inclination to the stern in the section S from the nose perpendicular to 0.12–0.15 of the ship length and limited extent of board surfaces along height H, equal to not more than 0.83 of superstructure height. Bearing surfaces within rod stem have rounding to DP, and surface of bulb is made in form of hemispheres elongated in vertical plane and symmetrical relative to DP.

EFFECT: technical result consists in improvement of efficiency of fishing vessel operation.
