I hadn't thought tape would bond well enough with coroplast to hold the centerline seams on this version, so my DIY efforts were limited to 8' and 10' kids' versions based on the largest sheets I could find. For 4mm coroplast (standard campaign sign material) the 8' one was quite sturdy, but the 10' version was too flimsy. It's maiden voyage ended after about 15 minutes with at least 6" of water inside the boat, and a huge kink just behind the cockpit. The middle was barely above the waterline with the bow and stern sticking up in the air. I'm surprised the 12' version shown in this video and the on-the-water test didn't fold in half when Time Tripper got in. For my son's 10' I wound up using a plywood cross section to stiffen just behind the seat, and an 8' length of 1/2" EMT conduit under the seat along the keel line. With these changes the 2nd outing was quite successful. Time Tripper's boat was flexing a fair amount in the middle; I bet a similar piece of conduit would also help his boat. You can cut the conduit into smaller sections and link them with 3/4" sch80 PVC like they use in sprinkler risers. That way the EMT keel sections could fit in the folded shell.
As for the price, yeah the current price is too rich for me. Hopefully if production and demand ramp up the price will come down. Don't forget, part of the cost of this thing is that a young architect is forgoing what he could make in salary at a Bay-Area A/E firm in order to design and create this thing. When you realize that at their current volume (say 500/year) that amounts to at least $150 per boat for just him, you start to realize why they are at the current price point. They are placing themselves higher than the cheapest inflatables, but below competing folders and higher-end inflatable hybrids.
