Bad idea to install aluminum decks.

Ah. That would explain why the vast majority of aluminium hulled boats
have aluminium decks.

It's an issue with hardware. Unless
one uses aluminum fittings (mostly must be custom-made) there will
be severe electrolysis problems between fittings and the aluminum
surface.

Not necessarily. But then I have 2 big Al workboats, so I have
practical experience. You have Google.

Composite decks are the way to go but cored composite consisting
of wood (ply or balas) is liable to rot if any water finds its way in.
Better to use some sort of plastic coring such as Kledgecell or foam
coring.

Composite decks on a metal hull are going to be a disaster where the 2
materials meet. The coefficient of expansion of Al is high. You'd
better buy bulk lots of Sikaflex or 5200. Even then the hull-deck joint
is never going to be as strong & waterproof as a metal to metal weld.

Not to mention that if you're worried about electrolysis on an Al deck
causing problems, what do you think tons of bolt & screw holes into the
composite deck are going to cause? Oh yeah, water entry and rot.
Duuuuuuh.
