FIELD: shipbuilding; building of ships used for enhancing ship's unsinkability.
SUBSTANCE: proposed watercraft has hull formed by longitudinal and transverse bulkheads with side, fore and aft buoyancy compartments which are hollow in form. These compartments form central open compartment (compartments). Hull is also provided with scuppers. Fore, side and aft buoyancy compartments are made in such way that their lower parts may be brought in communication with atmosphere. These compartments may be flooded with water to level of air cushion formed at this. Maximum buoyancy of watercraft is ensured at reduction of pressure in compartments due to dewatering of central open compartment which is not closed over perimeter through at least one scupper located at level of existing waterline corresponding to position of ship at flooding of central open compartment to level of said scupper.
EFFECT: enhanced safety of operation.
