Several methods have been presented to predict wave impact pressure for about ten years. Although their basic concepts about impact phenomena between a hull and waves are the same, basic equations of these methods are different which correlate actual impact phenomena with model tests or theories. The situation is very confused because they lack their complete physical explanations. This paper presents a simple method to correlate actual impact phenomena with simple model tests or theories and also presents a general aspect and physical explanations of modeling methods of impact phenomena. For the purpose to design structures, maximum impact loads must be determined with the magnitude and distribution of wave impact pressures. The old procedures to predict impact pressures give maximum impact pressures, but their distributions. It is very difficult to get distribution of impact pressures from 3-dimensional model tests in waves. This paper shows a method to get information of the distribution with 3-dimensional model tests. The results are comparatively good.
