Aluminum is relatively worthless for a boat hull.

All it takes to completely destroy the hull of an
aluminum hulled vessel is a handful of mercury
past smeared on it. It will begin to turn to dust within
hours, break apart and sink.

A stainless steel boat is impervious to just about
anything but strong acids.

Bwahahahahahahaha. It's obvious you know SQRT(f**k-all) about
metallurgy. S/steel is not a good metal to have in continuous contact
with seawater.

My biggest objection to aluminium is that its abrasion resistance is
low compared with steel and its ultimate failure point is too close to
its deformation point. Steel is a lot more ductile but does require
good barrier coats to keep rust at bay.

If money is no object, you build out of cupro-nickel.

Whats cupro-nickel? And why?

I hear nickle copper is best, the copper is a perfect antifoulant.
