Ok, as you pointed out the material dictates the design. SIP construction as a method is not readily amenable to curved shapes. I gave the wrong impression in my admiring the component nature of the panels and how they fit together. The method in which they were bonded, the fiberglass cloth are outside the comparison with Infused Panels and the way the get bonded. I get that.
But you must put curves into a flat panel to get a hull. It's all in the manner of which you bend that curve. How much can you put a curve into an infused panel is the paramount question? How much can a technique be applied to different cabin shapes is where I start to examine what's amenable.
