Hullo Joe......you do have a wealth of detail here
...just need to understand it
1. the two hydraulic wire winches pay out from the bottom of their drums.....the wires pass through the stern pair of hawser openings
2. the single hydraulic drum winch for the electrical umbilical cable pays out from the top of the drum, pass through the two vertical yoke rollers that are mounted on the hydraulic wire winch with the umbilical cable resting on the stern yoke plate above the wire hawser openings
3. there appears to be a Drafing error in that the hydraulic winch requires a double helix payin/payout shaft, this double helix horizontal shaft must be mechanically linked to the shaft that supports the two vertical yoke rollers, as these progressively feed guide and layer the umbilical cable back onto the cable drum
Mind you whilst the components are deck mounted....they are termed as Under Water Weapons, where as my role was specifically involved with Above Water Weapons
... so my knowledge is severely limited
.....
I hope this makes sense & have added a few notes in the images.............Derek
