In this paper, the effects of the following three appendages on fullship's stern are investigatied from the viewpoint of synthetic propulsive performance, i.e. propeller exiting force, propulsive performance and practical use. (1) Partial wake generator applied on the hull sur⊥ace directly be⊥ore the propeller (2) Under keel stern (U.K.S.) (3)Long fin applied along a potential stream line between S.S. 11/2 and S.S. 3/4 At first, tank tests, i.e. resistance, self-propulsion test and wake distribution mea-surement are carried out by using 1.92m and 4m models o⊥ SR 174B-4H ship with or without the above appendages. Using the tank test results, required horse power, bearing and surface forces are calculated and compared with each other. Consequenty, it is found possible to equalize the wake non-uniformity while improving propulsive performance at the same time, by properly applying such appendages to ship's stern.
