Broken cable could be a few different things.
A spinnaker pole has cables for the '"Topping lift" or pole up - actually it's a bridle. Also for the pole down. It could also have line or wire for opening the jaws (On a 44' C&C I'm guessing jibes are done dip pole rather than end for end). There could be just one of those.
So there's usually a swaged wire loop connecting the bridles to both ends of the pole. And then a shackle "Halyard" for the up and a similar downhaul for the down (Going thru an eye on the deck about mid pole). Some rig the down with some shock cord to allow a bit of play making adjusting the guy for the pole easier (You do not have to immediately release the down.)
That's about the best I can do without finding pictures on the web, which exist in abundance.
C&C's carry a large masthead spinnaker and on a 44' boat that can be a bit to handle.
