ABSTRACT:
A compact towing system which is adapted to be mounted on a ship for towing an underwater towed body using faired tow cable is provided herein. It includes an improvement in the combination of the following inter-related elements: (a) a trucked gantry; (b) a lower saddle; (c) a winch drum; (d) a boom; (e) a pivotable deflection sheave mounted inside the boom; and (f) a fairlead sheave and saddle assembly. Such assembly is mounted on a driven carriage. The improvement comprises structure and controls for driving the trucked gantry in synchronism with the winch drum. The driving of the trucked gantry (a) fore and aft is so related to the winding and unwinding of cable from the winch drum (b) that, as the trucked gantry traverses between a forward stow position and an aft full cable-out position, a zero degree fleet angle is obtained and maintained between the tow cable and the winch drum. Structure and controls are also provided for driving the driven carriage to traverse the carriage along the boom only during launch and recovery in synchronism with the winch drum so that, as the cable unwinds, the carriage is driven towards the outer end of the boom, in which position the fairlead sheave and saddle assembly overhangs the outer end of the boom. As the cable winds, the carriage is driven towards the inner end of the boom, in which position the fairlead sheave and saddle assembly lies along the boom. Thus, in operation the cable passes from the winch drum through a fairing training device, through the hollow boom pivot, around the deflection sheave, along the boom, through the fairlead sheave which is mounted on the driven carriage, and then to the towed body.
