Can I share the grounds for a bathroom fan and bathroom light?
Both low power, see no reason to run an xtra 10' of wire.

Re: Ground sharing
Yes but...
You have to assume that at some time someone will up the load. So you need to make sure that the ground can handle the FULL LOAD of all circuits sharing it.
If you have 2x10a and 1x15a circuits (fuse sizes) then you need to use ground wire capable of handling 35a continuous.
Hope that makes sense.

Re: Ground sharing
Keep in mind that if you have them all on the same supply circuits (fuse) then the the same gauge all the way will work. Once you separate the circuits then the ground needs to handle the combined fuses.
Based on use I don’t think you need separate fuses.

Re: Ground sharing
Normally you route all the grounds to a ground bus and then a heavier wire to the final ground. Depending on how many things you have on your boat that need grounding you may need more than 2 12 post boards. Check Blue Seas for there boards.
