TPU inflatable with Outboard Jet for Alaska rivers

Seeking guidance on building my own inflatable raft with 50/35 outboard motor with a jet on it. New hunting plans have my family wanting to go up and down the Yukon which has many shallow fingers and weaves.

Thinking 840D Dual sided TPU coated nylon. Rigid or soft hull? Preferably tunneled to maximize Jet while keeping shallow water capabilities.

I like to make things myself which is what brought me to inflatables for this desire.
going to start with a packraft, then this guy, hopefully in the next 6 months.

Thinking something similar or better and/or simpler than the solar, Stryker, pro jet inflatable models

seeking drawings, ideas, etc etc.

thank you for your time

 

Guess what's your definition of better/simpler? What features beat out say a solar or pro jet?

 

Here's a link to DIY pack rafts, if you don't have it already;

DIY Packraft – The homemade packraft how-to site & shop https://www.diypackraft.com/

It should give you an idea of what is involved in the process, and it should be fairly easy to do, with all of the detailed instructions plus I think the kit has all of the pieces already pre-cut. Not sure what's involved with a project for a larger boat that can handle 50 horsepower, seems like it would be quite a challenge to design something new from scratch, and for a much larger and more rugged boat. Something rigid might require the use of drop stitch material which may be hard to get in small quantities and that material may be harder to work with. I like soft hulls better, as they presumably don't jolt the passengers as much with hard collisions. Also, if penetrated, the air under low pressure leaks out more slowly, possibly allowing for a quick limp to shore, where a temporary tape repair patch might work.

I gotta say the shapes of the flat fabric are different than I'd first thought

 

Rigid.
