the surface was measured. Speed was then increased to eight 

 knots and the pressure signal again lost. Tension indica- 

 tions were recorded and 90-degree port and starboard turns 

 made with a standard rudder. 



Speed was then decreased to three knots and the tensiom- 

 eter removed from the line. The pressure signal was regained 

 when the speed was reduced. The system was in -hauled and, 

 due to a difficulty with the storage reel^, the cable was 

 f laked-out on the deck ahead of the winch. It was noted that 

 the depth signal was lost when the spliced section of the 

 cable traversed the stern sheave and was regained when the 

 traverse was ccmpleteo 



The in-haul was stopped at a cable scope of approximately 

 50 feetj and the system towed at a speed of six knots toward 

 sheltered water, vniile towing at six knots, the cable slipped 

 relative to the winch. Speed was reduced, the tensicaneter 

 attachments (without tensiometer) attached to the towline, 

 and the tow toward sheltered water continued at a speed of 

 six knots. Retrieval was completed after reaching sheltered 

 waters. 



After retrieval, the cable was flexed, under no load, 

 in the region of the splice; it was observed that the pres- 

 sure signal fluctuated and was occasionally lost during the 

 flexing. The signal was regained and became steady when the 

 spliced region was straightened.
