In the patent an underwater towing cable system is described wherein a non-Newtonian fluid is pumped from a towing ship reservoir, through a supply passage extending substantially the length of a faired cable assembly, for distribution through pores into a boundary layer of water adjacent the cable assembly. The pores may be limited to predetermined portions of the cable assembly and may be characterized by effective areas that increase proportional to position along the cable length, whereby fluid distribution is uniform irrespective of frictional losses in the supply passage.
