12vdc options are more readily available.
Why make a simple system (old boat) more complicated and expensive?
"Inverter batteries are usually a different set from house batteries".
This will be the case...
"Better inverters run on 12 or 24vdc (or more)".
Yes, but 24v is waaay more efficient (less prone to surge tripping)...
"Better inverters recharge their own batteries".
Yes, but I already own the inverter - it does not have a charger...
"12vdc options are more readily available".
12v won't run my 24v Go-Power inverter...Again, my goal is to have a 24v system (to the inverter), that will easily be reduced to 12v (via inexpensive Samlex dc to dc converter) at the 12v panel. The 12v panel will still be fully operable.

I don't really see this task as all too complicated or expensive except possibly for the 24v charger...I'd like to have a viable AC option in the event of no shore power...I'm retired so I think the project aspect might be fun. The key ingredent will be how to charge the 24v batt (actually 2 - 12v in series).
