The interaction between hull and propeller is investigated by a submerged body of revolution with full stern part. In the series of experiments on it, it can be concluded that for such macroscopic quantities as thrust deduction and the change of wake fraction with change of propeller loadings it is possible to analyse them by the potential theory, though the separation of flow may occur in the very near stern. The pressure on the hull is also measured when propeller is operating. The increment of the pressure as the number of revolution of propeller is increased systematically is measured and the change of the thrust deduction is calculated from it. The foundamental features of self-propulsion factors, when the propeller loading is changed, give the physically sound basis for the understanding of the self-propulsion factors of ship-like bodies. We can confirm in part that the self-propulsion factors could be determined by the potential theory from propeller loading tests of self propelling bodies.
