Doesn't welding all that steel add work?  No free lunch!

Ply, and other sheetgoods, can only be flexed into cylinder sections or conical
sections, or a few other similar shapes.  To a very slight degree, ply can be
"tortured" - that is to say, stretched - into additional shapes.  But cylinders
are the basis of most hull designs, in part because sheet steel is a sheet
good.  

I wouldn't sweat the geometry on this basis, I'd sweat it for can-it-do-the-job
reasons.  Getting the shape built is the easy part, in wood.
