DESIGN OF VESSEL
 
 
 
 
SUMMARY
 
     
  Comments are generally as given in the same section for 9C vessels.  The drafts of individual books available show great efforts being made to make the books for this type more concise than those for previous classes, by eliminating from them detailed information previously included.  Further, the war conditions affected the accuracy of the books for this class of vessel more than they did those for earlier classes, and the available vessels have been found to depart from the text in more particulars than do vessels of earlier types.  The principle on which the informational material is based remains unchanged, nevertheless.
