Several methods were recently proposed for the purpose of direct determination of wave-making resistance from the measured wave pattern. Among them, the method based on the Fourier transform of the wave profile at the longitudinal cut seems to be very excellent. The authors applied this method to the measured wave profiles of two models of the simple shapes and computed their wave-making resistance. The comparison of the above results with those of towing test showed a good agreement. It is also discussed in the present paper how to estimate the unavoidable error due to the measurement at a finite distance sideways from the ship, since this method of wave analysis is derived from the asymptotic expression of the wave pattern at an infinite distance from the ship.
