20. ABSTRACT (Continue on reverse side It necessary and Identity by block number) 



Hydrodynamic loading functions and drag coefficients have been developed for 

 a ribbon towcable. These functions represent a mathematical fit to data 

 measured on a towcable at sea. The functions should be used with caution in 

 predicting the towing configuration of other types of ribbon cable design or 

 other cable diameters because of the difficulty in scaling ribbon character- 

 istics such as material stiffness.
