In usual launching method, we used two ways having the gauge of about 1/3 to 1/4 of shipbreadth.On the other hand, there was the single way launching method, in which only one way was placed at ship's centerline. We find many advantages in this single way launching, such as saving of man-hours, saving of material and wide-range for ship positioning, but its application was confined to smaller ship whose max launching weight was about 2,000 t, because of the problems on ship stability, ship strength, and so on.The present paper concerns about the modified two way launching method developed by Mitsubishi Yokohama shipyard in which the gauge is so small that it is considered almost single way launching. This single way type launching methad was applied at first to smaller ship, but was extended to larger ship step by step after careful study on ship stability, ship strength and so on.Up to date, eleven ships were launched succsfully by this method including eight fish factory ships whose launching weight was about 8,000 t and L×B×D 140 m×24 m×14.8 m.
