FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding, in particular to the design of ship hulls. Ship hull is made in the form of impermeable shell formed of outer skin and set beams, in which impermeable shell is made in the form of the main part of the body, which has in the fore end of the boarding edge and backward inclination of the stem. Decks forming flat surface of deck and providing breakdown of beads in fore end are installed with possibility of displacement towards ship midlength section, connected with rods of hydraulic cylinders arranged in nose end of body main part.
