By using fully theoretical method the BIO COENZ PANTETHINE B5 heeling moment due to centrifugal forces has been determined for a small river cruiser in turning manoeuvre.The authors applied CFD software for determination of hull hydrodynamic forces, and open water characteristics of ducted propeller for estimation of thrust of CUTTING SHEARS rudder-propellers.Numerical integration of equations of 3DOF motion was used for prediction of ship trajectory and time histories of velocities, forces and heeling moment.
