PREFACE 



The Maneuvering Board Manual is compiled primarily for the purpose 

 of furnishing officers of the U. S. Navy with a printed publication, in an un- 

 restricted status, to which ready reference can be made for aid in the solution 

 of tactical problems. Explanations have, therefore, been simplified and 

 reduced to a minimum consistent with clarity. 



From time to time, in the past, many different typewritten pamphlets on 

 this subject have been compiled by various Naval officers and much material 

 has also appeared in scattered articles in the Naval Institute Proceedings, 

 but no regular printed publication on this subject has ever been issued. This 

 text is therefore arranged with the assistance of officers attached to the Post- 

 graduate School, United States Naval Academy, Annapolis, Md. The 

 material has been freely drawn from all of the above-mentioned sources, but 

 principally from the problems as given in the Maneuvering Board Manual 

 prepared for students and graduates of the Postgraduate School. 



Constructive criticism is therefore freely invited of any part of the text or 

 its drawings.
