Taking a large-scale container hull as a numerical simulation object, the computational fluid dynamics (CFD) theory is combined with the super-vacuolar drag reduction technique to reduce the hull boom resistance and total resistance. The hull type line is optimized, the joint drag reduction is carried out to improve the stability of the supercavity, and the SHIPFLOW software is used to simulate the hull resistance. The results show that after the optimization of ship types, because the wave peak change of shipboard is more gentle, viscous resistance is also reduced. Compared with the amplitude of the wave resistance, the change range of the viscous pressure resistance is smaller. The application of supercavitation technology has reduced the resistance of the wave, the reduced wave directly reduces the total resistance and the total resistance performance is improved. It showed that the automatic optimization of the ship's resistance performance has been successful.
