Five integrated faired towline configurations based on a blunt nose 

 fairing design were experimentally evaluated in the David Taylor Naval Ship 

 Research and Development Center deep-water towing basin to determine the 

 general towing characteristics of each configuration. Mathematical expressions 

 of the normal drag and side force coefficients are developed from the measured 

 data.
