Copper bottom
 

How about we make a lightweight copper hull shell, them resin the
inside with glass, etc. to make a boat that never requires antifoul?

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.
