This paper proposes a Rankine source method in conjunction with Kochin function for calculating the steady ship wave resistance. This method here is called Rankine Source Kochin-Function Method (RSKFM). RSKFM removes the negative wave resistance which is often calculated in the low speed range by ordinary Rankine source method. A wave resistance formula with new Kochin function in which the velocity potentials on the ship hull and still water surfaces are unknown variables is derived under Baba's free-surface condition. As application example of RSKFM, calculated results of the wave resistance are introduced for full hull forms. Through comparison of the results with model experiments, it was found that RSKFM considerably improves the prediction accuracy of the wave resistance.
