FIELD: transport.
SUBSTANCE: vessel for use at high speeds on rough sea has a hull (hulls) with fore end made with canted below BP keel line starting from 4-5 transverse section to vessel fore end for amount of 0.25-0.5 of draft up to design waterline on 1 transverse section. Hull(s) lines in the fore end are made with flam gradually increasing to board line. In addition, on the fore end of hull described above, bulb can be installed formed using flat, cylindrical and helical surfaces with rounding bulb longitudinal ribs along radius.
EFFECT: lower resistance to vessel motion on rough sea, reduced vessel pitching and rolling.
