As pointed out previously, the principal difference 
between the faired-cable case and the unfaired case lies in 
specification of the hydrodynamic loading. This is, providing 
the forces acting on the fairing are assumed to be transferred 
into the cable at intervals along its length as will he the 
case here, 
It appears that the clip-type fairing, illustrated in 
Figure 4, is a reasonable design upon which to base design 
calculations. Experimental evidence indicates that a configu- 
ration having a thickness-to-chord ratio of about 1/4 and a 
ratio of fairing thickness to cable diameter of about 0.8 is 
an optimum design. This configuration will have a drag coef- 
ficient, Cp, of about 0.2 in which case the expression for 
R becomes:

If it is assumed that the fairing, which is constructed of 
xubber, is weightless in water, then the expression for W is 
still that given in equation (2). Namely, 
w= 210 428 g? (2)
