FIELD: transport.
SUBSTANCE: invention relates to ship building, particularly, to designing high-speed single-hull vessels. Ship hull comprises right board (2), left board (8) and deck (4). Note here that fore (3) is arranged, in fact, vertically while underwater bow (6) is integrated with said boards (2, 8) nearby said bow (3) so that intersection (30) of fore (3) and bulb (6) is located nearby extending part (60) of underwater bow (6). Note here that the latter is shaped to bulb. Maximum vertical length (D) of said bulb make 0.9*(design draft)<D<1.1*(design draft). Curvature (R) of bulb (6) front makes 0.2*(design draft)<R<0.25*(design draft). Note here that every board (2, 8) above said bulb (6) makes acute waterline entrance slope γ making 10°<γ<20°.
EFFECT: lower drag.
