Four different techniques that use wave cut analysis to predict the wave pattern resistance coeffcient of a ship hull are compared. Two of the techniques are based on longitudinal wave cuts and two are based on transverse wave cuts. The results are compared with values from pressure integration and with towing tank measurements of the residuary resistance. Three hulls were used for the comparison: the Dyne Tanker, the Series 60 and the SSPA Ro-Ro Ship model 2062 having four different fore bodies. The wave cuts were obtained from linear and non-linear solutions of the free surface waves. A technique to predict free-surface deformation at any distance downstream of a vessel quickly based on the information computed in one of the transverse wave cut methods is presented.
