Abstract
The minimization of the wave resistance is discussed with respect to the hull form having a bulb at the bow. The main hull is represented by a continuous distribution of doublets and a point doublet is added at the forward end to illustrate the bow bulb. The main hull distribution and the intensity of the bulb doublet are determined in such a way that the wave resistance becomes minimum for a given displacement volume of the hull. Model tests involving the total resistance measurement and the wave pattern analysis are carried out to confirm the validity of the theory.
