B^ 









The resultant prismatic coefficient is 0.663, as desired, and the LCB is 0.985 percent 

 ^ gp aft of midships, as compared with 1.00 percent required, which is sufficiently close for 

 practical purposes. It is significant that this close agreement was obtained immediately from 

 the contours without any adjustment or personal factor being involved. This shows the use- 

 fulness of the Series to the designer for obtaining a set of lines which will fulfill the design 

 requirements at a very early stage and from which stability, capacities and similar quantities 

 can be obtained.
