Longitudinal-cut wave-pattern analysis is used to obtain the wavemaking resistance in water of finite depth. By considering the momentum flux through certain control surfaces, a resistance formula can be derived in terms of values of the potential function on a plane behind the ship and perpendicular to the direction of motion or alongside and parallel to this direction. Furthermore, by using the linearized wave theory the resistance can be expressed explicitly in terms of the spectrum of the recorded wave profiles. The wave profiles were measured in model tests carried out for three water depths HL 0.125, 0.1583 and 0.2667. The test speed covered both the subcritical and supercritical speed ranges. The total resistance was also measured simultaneously. Author
