Abstract
To examine the validity of the Froude-Kriloff Hypothesis, the exciting forces and moments of waves acting on ship models were measured. The results are shown in many figures in this paper. The differences of the Froude-Kriloff Hypothesis from the actual conditions are based on the facts that the incident waves are disturbed by the ship models.
It must be noted that the wall-sides of the experimental tank affect on the heaving forces remarkably at the wave length which is same with the tank breadth.
