Abstract
A new method of designing hull forms of minimum wave resistance is developed in which two major components of wave resistance, i.e., one due to free surface shock waves and the other due to linear waves are taken into account. A procedure of extracting wave profiles due to free surface shock waves is proposed, which is utilized as a quantitative measure of the magnitude of free surface shock waves. The relation between hull form and resistance coefficient due to free surface shock waves is empirically derived and it is incorporated into the wave-analytical procedure of obtaining hull forms of minimum wave pattern resistance, so that the sum of wave pattern resistance (linear wave resistance) and resistance due to free surface shock waves (nonlinear wave resistance) is minimized. The effectiveness of the new method is demonstrated by experiments.
