The report is confined primarily to controlled ship steering performance. However, steering performance depends on other factors not explicitly considered variables in the study but implicit in the nature of the problem. In particular, the study was concerned to a degree with the dynamics of ship hulls and rudder design and, thus, ship stability. Essentially, the study took the following form: find the functional relationship of all factors that affect the steering loop performance as a function of control modes, keeping the other factors that affect performance constant. For successful attack on this problem, it was necessary: (a) that the functional relationships be well understood and; (b) that the system be studied for realistic values of the 'constants'. Within these guidelines the study was restricted to a Mariner hull and conventional rudders. Eventually, of course, it will be desirable to explore other important areas of ship control, such as dynamic stability versus rudder activity and others.
