Abstract: A detailed comparison is made of calculated and measured ship responses to regular head waves. The comparison includes an analysis of the hydrodynamic force distribution along the length of an oscillating ship model in still water, the wave force distribution on a restrained model in waves and the wave bending moment distribution in regular head waves. The calculations are carried out according to the modified strip theory, which includes some important forward speed effects. The analysis shows that the calculations are sufficiently accurate for practical purposes, at least in the frequency range which is of interest.
