Abstract
This paper presents a practical calculation method of the ship maneuvering motion using the principal particulars of ship hull, propeller and rudder as basic input data. The mathematical model, which describes the ship maneuvering motion, is developed employing the coupled equations of surge, sway, yaw, roll and propeller revolution. Computations are made for various kinds and types of the merchant ships and for wide range of the maneuvering characteristics. The computed results show satisfactory agreements with the full-scale trial results. In addition, as an application study, the effect of the loading condition on the ship maneuverability is investigated through the simulation calculations. The conclusion is that the calculation method of the present study is very useful and powerful for the predictions of the ship maneuverability at the time, such as the initial design stage etc., when the principal particulars of ship hull, propeller and rudder are known.
