The problem of the hull-propeller interaction is of practical importance. Therefore, many efforts have been done with the purpose of getting knowledge of the functional dependance of the thrust force on the resistance of self-propelled ship. This paper deals with the experimental results of a submerged body of revolution under the action of propeller just behind the body. The purpose of the experiments lies in getting the basic experimental data, making an effort to find undiscovered facts and estimating the self-propulsion performance of the actual ship of usual form. The experiments are consisted of following items; 1) resistance tests 2) wake measurement on propeller disk 3) self-propulsion test: propeller is drived behind body 4) pressure measurement on hull surface. It can be said from the result of experiment that the submerged body of revolution could be replaced by a ship with full stern. And some questions for the procedure of self-propulsion test are raised.
