This paper contains the evaluation of the ship's maneuverability in the design stage during which the underwater hull form and the appendages are to be determined. For this purpose two basic aspects in the assessment of the ship's maneuverability are discerned. i.e. (I) thc determination of the influence of the hull form and of thc appendages on the ship's hydrodynamic phenomena such as added mass and damping coefficients. and (2) the determination of the effect of the hydrodynamic aspects on the ship's maneuvering properties. This second aspect will be elucidated by means of computer simulations which are applied for predicting the ship's rnaneuverability in the design stage. In the paper information will be given first about the hydrodynamic aspects by which the forces are generated on the hull in reaction to the ship's motions while maneuvering. After that the forces will be described which are caused by the rudders. Having determined all relevant hydrodynamic quantities, then the ship's maneuverability can be predicted by using computer simulations. Results from such simulations will be shown in comparison to model test results and to full scale trial results.
