INTRODUCTION 
In the design of cable-towed systems, the problem is 
complicated by the large number of independent variables 
which must be considered and the necessity for performing 
laborious calculations using tables of cable functions such 
as those in Reference 1*, There is a need, therefore, to 
provide the designer with a more simplified and rapid method 
for determining the feasibility of meeting system requirements 
and selecting system parameters which are in a range of prac- 
tical interest. This need for a more practical approach to 
cable-body system design was encountered in the course of 
studying requirements for a towed instrument array to be used 
in measuring physical characteristics of the ocean. Asa 
result of this study, sponsored by the Office of Naval Research, 
a design technique was devised to permit selection of a practi- 
cal configuration to meet requirements for attaining a particu- 
lar depth at a given speed using armor ed electrical cables 
both with and without cable fairing. Since this method is 
felt to be generally applicable to a variety of such design 
problems, it is described in this report as a separate part 
of the study.
