Experiments are described in which the amplitudes of heave force, pressure at selected girthwise locations, and radiating waves, as well as the phase angles of force and pressure were measured for several heaving cylindrical bodies. These results are compared with theoretical values computed according to Porters work. Excellent agreement is found between theoretical and measured amplitudes of force and pressure. The agreement for predicted and measured wave heights and for phase angles is substantially good. The feasibility of obtaining total force by a girthwise integration of measured pressures is shown. The results and techniques are expected to shed further light on the problem of the response of a ship to a seaway.
