Аннотация:The dynamics of a catamaran with a Savonius rotor and a propeller installed on it is
considered. Under the action of a stationary wind flow the rotor rotates and transmit it to the
the propeller, which creates thrust. As a control, the angle of the catamaran's course relative to
the wind flow is considered. The control task is to move the center of the masses of the hull
from the starting point to a given endpoint located strictly upstream of the wind. The possibility
of straight motion against the wind is shown. The dependence of the averege velocity in the
stationary mode of movement against the wind on the radii of the Savonius rotor and propeller
is analyzed.
