Wondering if there are any merits to aluminium construction in a catamaran vs composite ie balsa end grain?

Theres not many examples online so just wondering what the advantages would be vs troubles in construction.

I guess most peo0le would be able to glue glass and cove , but how many can weld?
lizard yachts are not too bad and then you have the Mumby,s all good cruisers

this one is impressive,

You can go bigger with aluminium. I had an alloy cat 25ft motorboat, great for parking up on the beach and easy beach launching without worrying about scratching gel coat. But being very light it wasn't a smooth ride, you felt every little bump.

Its downfall was electrolysis, during construction a packet of steel bolts got dropped between the outer layers, after noticing rust we cut out sections and removed them, but it kept happening in other spots and we never got them all, someone must of knocked over a whole packet of nuts and bolts and never bothered to clean them up, that little issue compounded into a bigger one and it ended up sinking the boat 10km offshore. I wouldn't hold that against alloy boats though, just poor workmanship in the build.

Unless you factored in some pretty good airtight pockets you would lose the safety factor of being unsinkable or at least sinking very slowly.
