Analysis of Ship-Side Wave Profiles 



The second order calculations for hull-surface condition as 

 well as for free-surface condition are found insufficient to give the 

 theoretical bases of the obtained correction function a ( £ ), which 

 suggests the importance of the hull's sheltering effect. 



Considering a ( £ ) as a correction function, M 21 -M is 

 designed under the same restraint condition as that of M 21. From 

 towing test results, it is proved that M 21 -M is much less that 

 M 21 in wave-making resistance and such a design procedure is si- 

 gnificant.
