FIELD: ship building. ^ SUBSTANCE: proposed marsh motorboat comprises hull with engine, frame, two auger base elements, hydraulic pumps, hydromotors and hydraulic jacks. Frame represents lengthwise beam sections with cantilever cross-arms arranged at an angle to each other and pivoted to said beam sections at the front and rear. Hydromotor stators and cylinder shaft bearings supports are pivoted to cross-arm free ends. Hydraulic jacks interconnect cross-arms via pivot joints. Hydraulic jack chambers and those of hydromotors communicate, via high-pressure hoses, with hydraulic pumps. Cylinder chambers are made tight. ^ EFFECT: higher maneuverability. ^ 4 dwg
