That would be great but sadly is not going to happen. Most battery banks that folks are willing to pay and find room for have the fuel equivalent of less than a gallon.

The capacity of today's battery banks are amazingly low compared to fossil fuel.

In my scenario however with the usage of the boat being sailing for 3 to 6 hours then being off the boat for shore visits the charging can be done by either generator or shore power while we are off the boat.

I want the option for safety and itinerary flexibility to forget about battery limits (and our precious tranquility) and just motor for as long as our 30 gallons will take us.
