the last digit gives the overall fineness ratio, i.e., the 

 ratio of the overall length of a right-section of the fair- 

 ing plus cable, to the diameter of the cable. A trailing- 

 type fairing with a thickness ratio of 8/10 and a fineness 

 ratio of 4 was selected. 



The fairing is constructed of a single-durometer 

 rubber; the leading edge is reinforced with a five- or 

 six-ply Dacron tire-cording to provide the necessary 

 structural strength. The ends of the Dacron cording are 

 turned back to form a loop, as shown in Figure 4. 



The fairing is to be procured in maximum lengths of 

 200 feet; shorter lengths may be specified, as required, 

 for lesser module spacings. It may be produced from 

 Bureau of Ships Mold G60818. 



CLIPS SEP Drawing No. 101137 



The fairing is secured to the cable, at intervals of 

 four inches, by clips which encompass the cable and are 

 free to swivel thereon. It is attached to the ears of the 

 clips by rivets passed through the rubber body aft of the 

 Dacron-cord reinforcement.
