In this paper, firstly, the prediction method of wave-exciting forces for lateral motions of ships has been investigated. The measurements of wave-exciting forces and moments acting on ship models were carried out for the cargo ship (C_B=0.812) and container ship (C_B=0.562) and their results were compared with the calculated results by the strip theory. It has been clearified that the calculated results using two dimensional hydrodynamic forces obtained by the Close-fit method coincide well with the experimental results. Secondly, it has been numerically confirmed that the roll response in beam waves obtained by the equation of motion of roll with the wave-exciting moment based on the Froude-Kriloff's theory is in good coincidence with the one by the coupled equations of sway, roll and yaw motions.
