Generally, there are some advantages about a mono hull type high speed craft, such as simple structure and availability for using existing port facilities, then mono hull type is used mainly in high speed crafts. However, in regard to a mono hull type craft, it has been known to lose the transverse stability occasionally with increasing her ahead speed, even though she possesses adequate stability at rest condition. Despite the relative severity of the phenomenon, very few is known about the fundamental characteristics. There are some technical literature concerned with stability phenomenon by experimental method. However, there is few examples that approach this phenomenon by numerical calculation method. In this paper, numerical calculations on the transverse instability are carried out for dynamic pressures, rolling and yawing moment acting on a high speed craft, by applying Prof. Maruo's new slender ship theory. This paper deals with the high speed instability phenomenon on the assumption that she has constant speed, heave, trim and heel angle.
