Wave-free floating body forms in shallow water are studied using a wave-free singularity that is made by a source and vertical dipole combination to generate bulbous-shaped two- and three-dimensional bodies. The wave-free floating body is free from wave exciting vertical force in waves, which is equal to having zero radiation damping in heaving oscillation in calm water. Shallow water effects on the body form appear to make the body more slender as the water becomes shallower. Wave exciting forces of thus obtained body are calculated by the singularity distribution method to verify the wave-free characteristics at the designed wave-number. Variations of body forms in the depth of water are presented graphically in two-dimensional and axisymmentric problems. Experiments are conducted for the models obtained theoretically and the results are discussed in comparison with the theory. They generally agree with the theoretical predictions.
