Grounding Questions

Hello there!

I've recently bought an '84 Catalina 25, and its wiring needs to be completely redone. My biggest source of confusion right now is is determining where the ground wire is, if it exists at all. I don't believe it had an inboard motor at any point, which further enhances my doubts. Is it possible (and appropriate) to ground the electrical system on the keel bolts alone? Should there be different grounding systems for my AC and DC systems, or can they all be connected to the same grounding bus, in turn connected to the bolt? Lastly, what about grounding for lightning on the keel, if other grounds are already connected?
