I was reading about the latest Anfibio ultralight packraft and something jumped out at me. “The entire boat consists of only three main segments (compared to normally 11 individual segments). This is achieved through circumferential, horizontally arranged seams (instead of several radial seams).”

I did some Googling and I found this guy who designed a minimal packraft using the same idea.

Is it possible to design a simpler, lighter packraft with only flat seams to weld? Definitely the more more complex the shape the more seams, but can you still end up with a modern packraft shape (extended stern, pointed bow)?
Has anyone played with this idea? What kind of CAD software would be needed? I found a technique was developed by Disney in 2014, but can’t find any further resources or instructions. There’s also a plug-in called ExactFlat for Fusion360 but I can’t tell if it will work for inflatable materials.
