An investigation into the mode factor in the calculations of hull response in the higher mode of ship vibrations was carried out. Since the factor C_n is represented by C_n=Δ_1y(u)y(v)/∫^L_ow・y^2dx the load distribution of ship including added mass greatly affects the mode factor. It was clarified from the calculation that the cause of irregularity of C_n curve for the number of nodes of the vibration is due to the discontinuity of load in its distribution. It has been suggested that as a considerable variety of C_n for the distribution of load is accounted in a ship with various load distributions, numerous charts of C_n for various loading conditions should be prepared for a designer. Further collection of C_n-value as well as the damping factors by the exciter tests on board ships should be required.
