My gut would suggest tying the three together, and including a "galvanic isolator" to your AC line, if you use an AC shore power cable for charging.
I would think you really wouldn't want to have floating stuff going on between your 12V and 48V systems.
If they really are completely isolated, then you should be ok. But if there was ever any crossing, things could get weird (or at least look weird) fast.

Subject: [Electric Boats] grounding
So I have three things that I could tie together: the prop, the ground of the 48V system and the ground of the 12V system.
Instinct tells me I should tie all the grounds together.
But why?
Are there any disadvantages to leaving them floating?
