In practice, the vehicle development is stipulated by a useful effect that is attained upon the vehicle operation. The useful effect for transport ships consists in cargo transportation. Thus, the ship efficiency as vehicle efficiency will be determined by commercial effectiveness. Comparing the efficiency of the different methods of the hydrodynamic drag reduction with efficiency of the artificial and vapor supercavitation, one can see its advantage and, hence, perspective of its use. Moreover, a vapor layer between the water and hull unites many methods of the drag reduction.
