so, watched this thread from it's start, let me give you a little bit of info, re, aluminium vessels.
They do not rust.
They do not leak
They are inherently strong.
They do not decline over years unless painted.
salt, fresh water,no impact unless poor maintenance and ownership.
Cleats do not break or fall off.
The vessel does not twist in heavy seas.
Unlike Polyester boats, they do not "cure" continually.
Finally, if you dress them like ladies, what else is there to say ? They are GREAT.
