FOREWORD 



The research on Series 60 was carried out at the David Taylor Model 

 Basin of the United States Navy. The results were published in the first 

 instance in a number of papers before the Society of Naval Architects and 

 Marine Engineers. 



From time to time the wish has been expressed that the results of this 

 research should be assembled in a single volume for easy reference and use. 

 The original papers described a great deal of preliminary work carried out 

 before the final Series 60 was adopted, and because they were read at inter- 

 vals over a period of nearly 10 years, they also contained a certain amount of 

 duplication and connective matter. 



The opportunity has therefore been taken to completely rewrite the text, 

 which is new, eliminating the preliminary work and much of the history, and 

 also, it is hoped, most of the errors which are seemingly inevitable in a research 

 of this magnitude. 



In presenting the collected results in this new version, the author wishes 

 to express his indebtedness to all the Staff of the Model Basin who have worked 

 on the project since its inception in 1948, particularly those who have been co- 

 authors in the original papers— Capt. F.X. Forest, U.S.N. , Mr. J.B. Hadler, 

 Mr. G.R. Stuntz, Dr. P.C. Pien, W.B. Hinterthan, and N.L. Ficken. 



Mr. Hadler and Mr. Stuntz have been most helpful in reviewing the 

 present text, although any opinions expressed are those of the author. 



The whole project was carried through under the general guidance of a 

 Panel of the Society of Naval Architects and Marine Engineers, the members of 

 which devoted much time and thought to the choice of parameters and the detail 

 design of the Series. The following people served on this Panel from time to 

 time— Professor L.A. Baier, Mr. J.P. Comstock, Mr. H. de Luce, Capt. F.X. 

 Forest, U.S.N., Mr. J.B. Hadler, Admiral CO. Kell, U.S.N. , Professor G.C. 

 Manning, Mr. V.L. Russo and Dr. F.H. Todd— the successive Chairmen being 

 Admiral Kell, Dr. Todd, and Mr. Hadler. 



Thanks are especially due to successive Directors of the Model Basin 

 who have throughout supported the research— Admirals CO. Kell, G.H. Holder- 

 ness, A.G. Mumma, W.H. Leahy, E.A. Wright, and Captain J. A. Obermeyer— 

 and to the Bureau of Ships which supplied the finance for most of the work 

 under the Fundamental Hydromechanics Research Program, assisted towards 

 the end by the Maritime Administration and the Society of Naval Architects 

 and Marine Engineers.
