In the bottom of this ferry , a Roman shaped profile sheet ,instead of a honeycomb structure, was broken Z vise , chacking all profiles ; no worry the ships authories say it don't affect hull strength ,this is still not my subject.
Just the uniformaty in extruted sheet hull material ,by structura _ask_ the kind of dameage skin structures will perform. Sheet material can be made forming any nice shape just seing the design as a double honeycomb structure , what make anything even crazy, are when occations that _are_ bound to be with Roman slow motion ,can't even bring a better solution to the strengthvise problems in catamarane design , then why not build it a third the cost, four times as strong, much safer for transport means.
Sorry I don't have a graphics with the sheet Roman Z vise crack, just ; this wouldn't happen with 3D-H and rather prove the weak points with known technikes ; want a hull where any stress are equaly shared by structure ,then just transform a framework into a honeycomb structure.
