Abstract: The coefficients of the pitch- and heave equations have been experimentally determined for the model of the Davidson A-destroyer with a bulbous bow. Moreover the wave-forces and -moments on the restrained model have been measured in different head waves. These measurements are compared with the results of computations based on two modes of strip theory and on a ‘rational’ strip theory for slender bodies. The motions have been calculated with both the computed- and experimentally determined coefficients, forces and moments and are compared with each other. A comparison for one speed has also been made with the measured motions of the Naval Ship Research and Development Center (NSRDC) and the measurements of Breslin and Eng.
