Abstract : The objective of the study was to examine the relationship between forward ship motion and the effects of aerodynamic and hydrodynamic disturbances on motions in the horizontal plane. It includes course control and stability analysis for the unsteered and steered cases (manual and automatic) using several sets of operating conditions. Hydrodynamic and aerodynamic effects are considered to be functions of hull motion, rudder (steered cases), propeller and wind effects ratio. A dimensionless mathematical model has been developed and solved with respect to ship axes. (Author)
