Figure 8 - Wave-Resistance Coefficients of Symmetrical 

 Bodies as Defined on Figure 4, f/L =0.5 



it appears that the resistance curves R (y ) plotted over y Q have a vertical 

 tangent at y =0, but no attempt has been made to draw accurately the range 

 of curves below y = 0.5- 



To obtain a general idea of the wave resistance for various symme- 

 tric distributions //(£) (sectional-area curves A*(|)) graphs have been plot- 

 ted for following simple cases:* 



*As before, by symmetry we mean symmetry with respect to the midsection.
