Previously, some experiment and analysis had been done on ship hydrodynamic forces acting on the block type ships moving oblique. As the analyzed results, the elements composing hydrodynamic forces showed a big different characteristics from ones of an ordinary fine ship, especially on the drag to lift ratio. On this case, it is considered that sharp corners sections at both ends of bow and stern, may cause a lot of induce drag existed in the motion. Then, in order to investigate the cause, several ship models transformed on bow or stern shape have been examined on ship hydrodynamic forces by means of oblique towing test. As the result, the characteristics of hydrodynamic forces show a great change and variation due to the transformation on the stern shape of the model.
