ABSTRACT:
A towed body deployment/retrieval system which includes first and second hollow arms for passage of a cable from a winch to the towed body. The adjacent ends of the arms include forked fittings which are in cooperative engagement with a slip boundary sheave having, in a peripheral channel thereof, an endless belt slidable in the channel and having a groove which receives the cable. The arms are movable relative to the slip boundary sheave over a limited distance during normal usage. The slip boundary sheave rotates about an effective center located outside of its contour and accordingly is much smaller and can fit into a smaller space than an equivalent circular sheave which would normally be required for the same diameter towing cable.
