This report describes ship motion trials that were carried out on the Attack Class Patrol Boat HMAS BOMBARD off Sydney during October 1976. The patrol boat carried out runs at 10, 15 and 19 knots into head, beam and following seas. Data on roll, pitch, lateral and vertical acceleration are presented. Waveheight measurements were made with a Datawell Waverider Buoy. This report presents the spectra of roll, pitch, vertical and lateral acceleration and waveheight. An analytical method of obtaining the spectrum of the rate of change of a function given its spectrum is derived. This resulting transformation is used to obtain the spectrum of the rate of change of vertical acceleration which is an important quantity in seakeeping and motion sickness studies. The transfer function of the patrol boat when it is considered as a system with the waveheight spectrum as the input is obtained. (Author)
