B. For larger depths of immersion the dependence of the peak values of 

 R/A upon <f> becomes more pronounced; the advantage of high prismatics in the 

 range mentioned in A(2) is, on the average, reduced. 



4.3. RESISTANCE CURVES OF ASYMMETRICAL BODIES 



Further curves representing the wave-resistance coefficients of the 

 four TMB models represented in Figures 14 and 15 are shown in Figures 16, 17 

 and 18. Before discussing these particular asymmetric models, however, an 

 investigation must be made of the influence of asymmetry on the resistance. 



Figure 5 represents examples of asymmetrical lines belonging to 



the family 77* = £ + b £ 3 - (1 + b ) | 5 , Equation [4g].
