About the longitudinal stability of a high speed boat in still water, Perring and others researched. In this paper the longitudinal motion among waves is adopted when it moves at right angle to wave lines, and the conditions not jumping above waves are researched. It means that the higher wave height is the more unstable a boat becomes and when wave height tends to zero, namely still water, it is stable surely. Also where the boat velocity is equal to the wave velocity, the boat position to the wave surface is constant, so no jump. The resistance derivatives used in it are introduced from the results of Sottorf's experiments and the stability of a single step boat is discussed. By those resistance derivatives the longitudinal stability of actual boats among waves is calculated.
