What is neat is the lack of hull maintenance, and durability.

Building for a lifetime is the concept.

It would have been better done without the steel framing.
Why have any maintenance on that sort of thing?

How about graphite frames, Bart? Talk about maintenance-free and no risk of
galvanic interaction.

Graphite conducts electricity. I just Googled galvanic series
and was surprised to find Graphite on the top of the list.

So graphite frames would cause Asperenda's copper to corrode!

* Graphite
* Palladium
* Platinum
* Gold
* Silver
* Titanium
* Stainless steel (316 passive)
* Stainless Steel (304 passive)
* Silicon bronze
* Stainless Steel (316 active)
* Monel 400
* Phosphor bronze
* Admiralty brass
* Copper-nickel
* Molybdenum
* Red brass
* Brass plating
* Yellow brass
* Naval brass 464
* Uranium 8% Mo
* Niobium 1% Zr
* Tungsten
* Stainless Steel (304 active)
* Tantalum
* Chromium plating
* Nickel (passive)
* Copper
* Nickel (active)
* Cast iron
* Steel
* Lead
* Tin
* Indium
* Aluminum
* Uranium (pure)
* Cadmium
* Beryllium
* Zinc plating (see galvanization)
* Magnesium

I know it's on the nobility list, but I've always assumed that it won't
allow ignoble metals to plate themselves upon it. So how will that cause
galvanic corrosion? If the copper ions are released, where will they go?
I'm not being contradictory--I'd really like to know. I've never quite
figured out why graphite is atop the list.

Both would need to be in an electrolite. The boat would have to
be full of water--then you'd get some copper plating on the graphite.

I don't have a clue about why graphite is at the top. I'll ask a friend
who is a chemical engineer.
