I am finishing up my bonding and suddenly have a brain freeze. I have #6
green wire tied to all the exterior metal, the fuel tanks, the chain plates,
keel etc. They all come back to a central post mounted on the engine
stringer and tied to the block from there. AC neutral and ground are
separate back to the shore power receptacle but the Prosine inverter has a
boat ground that automatically disconnects when on shore power. .

Now the question. The stock alternator (used for the starter bank only) is
grounded through the block so the negative side of the starting battery is
connected to boat ground but the big house alternator and all the house DC
circuits are currently isolated. Should I tie the negative side of that to
boat ground too?


Yes!

Your SSB in particular will benefit from a common DC boat ground.
