PREFACE 
The David W. Taylor Lectures were initiated as a living memorial to our founder in 
recognition of his many contributions to naval architecture and naval hydrodynamics. 
Admiral Taylor was a pioneer in the use of hydrodynamic theory and mathematics for the 
solution of naval problems. The system of mathematical lines developed by Taylor was 
used to develop many ship designs for the Navy long before the computer was invented. 
He founded and directed the Experimental Model Basin; perhaps most important of all, 
he established a tradition of applied scientific research at the “Model Basin” which has 
been carefully nurtured through the decades and which we treasure and protect today. In 
the spirit of this tradition, we invite an eminent scientist in a field closely related to the 
Center’s work to spend a few weeks with us, to consult with and advise our working staff, 
and to give a series of lectures on subjects of current interest. 
Our tenth lecturer in this series is Dr. Yasufumi Yamanouchi who is currently 
Technical Advisor to Mitsui Engineering and Shipbuilding Co., Ltd. Dr. Yamanouchi 
graduated from the Tokyo University in 1943 and received his Dr. Eng. from there in 
1962. For many years (1946—73), he served with the Governmental Research Institute on 
Ship Technology, that changed its name from Railway Technical Research Institute 
(1946-50), then to Transportation Technical Research Institute (1950-63), and finally to 
Ship Research Institute, Ministry of Transport. He was Head of the Ship Performance
