Application of Wavemaking Resistance Theory 

 CONCLUDING REMARKS 



While fully aware of the limitations of the existing theory, we believe that 

 useful results have been achieved without exceeding these limitations. By re- 

 stricting the analysis to forms of absolute low-wavemaking we have not unduly 

 violated the linearization at the free surface, and by recognizing the relative 

 importance of forebody wavemaking we have avoided some of the problems of 

 viscosity. 



The idea of reducing the viscous drag of a ship through the application of 

 the wavemaking resistance theory is rather interesting. It may have an impor- 

 tant influence in the design of future ships. 



However, even though the arguments used in this paper to support our views 

 and ideas are quite logical and plausible, the final proof of the validity of these 

 arguments rests on model experiments to be carried out in the very near future.
