FIELD: transportation.

SUBSTANCE: invention relates to water transport and can be used for ships intended for operation in water areas with limited depths. Wheel steering unit with feathering paddles is located in the afterbody and consists of two paddle wheels of symmetrical design with screw paddles that have a separately controlled drive. Paddles are hinged at an angle to the axis of the wheel to the ends of the arms of the carcass rigidly mounted on a hub of right and left wheels fixed to a free end of the corresponding screw shaft, which is supported by bearings on the axis of the starboard and port, mounted in a cantilever fashion on the right and left side walls. On each fixed axis, an eccentric is fixed, the rim of which is connected in a plane of rotation hingedly with a fork traction which is connected to the driving paddle by the other end by means of a ball joint and a crank, and the remaining paddles are connected to the rim of the eccentric by means of crutches and ball joints at the ends of the rod drives.

EFFECT: efficiency upgrading and controllability are achieved due to the use of a pair of paddle wheels with feathering propeller blades symmetric about the dynamic positioning of propellers.
