Thanks for the reply, Matt. The the photo of the old seat is along the bottom, back right edge. It peeled back about halfway to the reinforcing strips on its own. The fraying didn’t start happening until the fabric pulled away from the TPU.
As for the attachment points along the side they too peel with little force. The ones shownare just for the new backrest. I copied Alpacka’s design a bit on this one. The multiple attachment points prevent twisting and should equalize load with how they’re currently rigged, not multiply– I took the photo with the boat deflated, I’ll get a photo of the system with air in the boat. (I studied physics and have a lot of experience with rope rigging and forces on those systems) Additionally, I keep my drybag behind the seat back– the main load is held by the stuff behind it. I’ll get better photos of the rigging and usage tomorrow. Most thigh strap tie-in points will see way more force at the end points due to the shallow angles involved, and those seem to be holding up fine with similar surface area tie-ins.
How would you rig the seat back further forward without tying the back in on the tubes? I am pretty darn short, and I’m in the smallest Skeena– even pushing myself forward several inches isn’t quite enough, even with something
