Launching from slip way being carried out into Onomichi Channel with breadth of about 240m, by using drag weight in our yard, it needs high technique of stopping ship's body within a tolerance of some 10m, according to the length of ship. There is a trend that actual launching travel is usually larger than estimated one, to some extent, the cause of which has not been revealed but may be considered to depend on the long peniodic wave motion in the channel, induced by launching ship. Authors calculated wave profiles for the simple simulation in order to know the mechanism of wave motion at launching, the result of which they applied for the launching, modifying the existing equation of motion, and got reasonable coincidence with the measured data. However, it is very difficult to estimate hydrodynamical force acting on the launching body exactly, and should be our main theme in future.
