The intensive investigation into ship waves was performed on both short S-201 (L=3.5m) and long S-201 (L=23.5m), extremely long slender-ship. Some interesting results of experiments on an extremely long slender-ship are obtained. It was shown that the first-order wave-making theory could not explain the peculiar behaviors of the waves generated by a long slender-ship. This new finding will lead to a new field in the wave-making theory. Intensive investigation into the waves far behind a ship revealed that the waves near the body differed from the waves away from the body. And the rate of decay of waves was much larger than that theoretically anticipated. The results of experiments on the shorter model suggested that there may be some effect of wakes on the wave pattern far behind a body. Also the longer model suggested that the existence of the extremely long parallel body strongly affected the wave pattern near the body. Some researchers expected theoretically the peculiar behaviors of waves created by a long slender body. But there have not been experimental evidences. This paper will provide some important evidences for the theories. In appendixes the full explanation for the longitudinal cut method is given together with the method for the second order truncation correction.
