SINKAGE AND TRIM IN FIRST-ORDER THIN-SHIP THEORY

In first-order thin-ship theory, the sinkage and trim of a ship moving with constant speed into still water can be obtained from a pair of linear equations associated with force and moment. The right-hand sides of these equations are triple integrals of the Havelock source function over the undisturbed underwater profile. By approximating the hull form by a piecewise linear one, these terms may be taken to be composed of two distinct types of integrals whose values are calculated. Sinkage and trim for two mathematical and five Series 60 Models have been calculated using these integrals. The results are compared with the corresponding experimental values. The agreement between theoretical and experimental values is considered satisfactory, especially for sinkage and for sufficiently small beam/length ratio.
