In the 80m square tank in Ship Research Institute long crested oblique regular waves were generated by the snake motion of 24-segment wavemaker moving each segment with the same amplitude and with constant phase difference. This experiment was conducted to investigate the technique for generating oblique waves and the properties of them, which are the basic data for reproducing the real sea (multi-directional waves) in a test tank. It is clarified through the experiment that regular waves which propagate at an intended angle to the wavemaker can be generated by setting the phase difference between adjacent segments according to equation (4) under the restriction of equation (5). One characteristic of these waves is that they are limited in specific areas in the basin, and the other is that the wave heights show a wavy feature spatially and by wavelength. This phenomenon seems to be attributed to the end effect of the wavemaker and the length of each segment that is not short enough.
