FIELD: transport.
SUBSTANCE: invention relates to ship building, particularly, to displacement vessel with air cavities. Displacement vessel is equipped with the device to creating artificial cavities at flat bottom consisting of transverse nozzle arranged one after another over vessel length and composed of plates, lengthwise limiting keels mounted at bottom and source of forced air feed via pipes under vessel bottom to create and maintain cavities behind said transverse nozzles. Said transverse nozzles can be opened and folded to abut the bottom by their turn about their lengthwise axles arranged at vessel bottom. Said lengthwise keels are composed of elongated inflatable containers.
EFFECT: improved capabilities for navigation in shallow water and rough water.
