Abstract : An improved fairlead reduces the problems associated with deploying and retrieving a towing cable and its interconnected elongate instrumentation array. A pair of parallel rollers orthogonally disposed to a storage winch reel are spaced apart to present a smooth, protuberance-free surface to accommodate the elongate instrumentation array. A shell coaxially disposed about each of the cylinders is rotated to cover the smooth protuberance-free surfaces and present a pair of abrasion-resistant surfaces when the towing cable is reeled in or payed out. Since it is likely that the abrasion-resistant surface might be scored by the towing cable, rotating the abrasion-resistant surfaces out of the way to expose the protuberance-free accommodating surfaces when the array goes through the fairlead helps reduce the possibility of damage of the elongate instrumentation array during deployment and recovery.
