How about we make a lightweight copper hull shell, them resin the

If it was copper welded, it might need only very thin copper foil and
the cost played against other maintenance and advantages could be a
savings.

As I do not have any idea what this would cost to do I ask this forum
for knowledge, if there is any available? It's essentially a
substitute for gelcoat, no?

When the Royal Navy enthusiastically adopted an idea [of Humphry
Davy's??] to galvanically protect their copper bottoms, the copper
erosion stopped, but the marine growth started up big time.
They canned the protection within months.
Take home message: what don't dissolve, don't protect.
