Turning Ability,on through a rudder and the terms associated with the turning circle. The phases of the turning circle are explained by considering the hull, rudder and inertia forces that act on the ship as it turns. The behaviour of the ship during a turn is also explained through the equations of motion and it i

Speed Changing,r a desired speed change and the distance travelled in that time but this method has some problems which are explained. There are some other factors that affect speed changing and these are described. The stopping manoeuvre is explained in some detail. A numerical simulation of this manoeuvre is dif

Effects of Propellers and External Forces,ler operation. How this transverse force and turning moment arise in a single screw ship is explained. In a twin screw ship, the transverse forces and turning moments of the two propellers turning in opposite directions cancel each other. However, twin propellers also affect manoeuvring since during

Environmental Effects,or the effect of wind is described. The effect of a current in water is taken into account by considering the motion of the ship with respect to water. A study of ship manoeuvring in waves requires the combined study of both manoeuvring in calm water and ship motions in waves and the computational m

Manoeuvring Model Tests,racteristics while captive models are used to determine hydrodynamic derivatives. In using model tests to determine the hydrodynamic characteristics of a ship, it is necessary to consider the laws of similarity relating the behaviour of the model to the behaviour of the ship. The conduct of the vari

The Nomoto Model,essions obtained for the Nomoto indices in terms of linear hydrodynamic derivatives. The significance of these indices is explained. Methods are described to determine the first order Nomoto indices from the data of ship manoeuvring trials or model tests. Some empirical methods to estimate these ind
