Really feel for you. I know that feeling when a project goes sour and you just work in frustration and anger.
If it is in EU I might be interested. But to be totally honest, you wont get all your money back as it is sounds like a gamble. I have built one myself but my brother is also interested in one and I might build it for him as a present.
First I would want some more details on how many of the joints that have glue in them and the status on the floor joints as those will be tricky to go over.
I first used a modified soldering iron but quickly shifted to one of those lether irons. I can use it in 50% temp and highly recomend it for the thicker fabrics and thougher seems.
Still have hope for you and think you should wait a little bit with the decision. Maybe try with a higher temp iron and really let it take the time you need.
If you decide to sell it you will probobly get more money from someone who could inspect it more and pay a correct price so maybe start there.
If you have a cargofly you could simply use one or more beach balls and put it inside before inflating it. It will keep it afloat and you have something to play with when waiting for rescue 🙂
I might do take some more explaining pictures when I make the next one if others are thinking of something similar.
The tube to circular patch was the tricky part to figure out but eventually I found a easy method. The 8 pizza/flaps pieces are overlapped so that there is no gaps but I reinforced with seamgrip just to be sure.
The bottom is as simple as it gets, inside the tube there is a rectangular patch of double sided TPU. The cord is used to tie it to the bottom of the tube section where I have two loops attached to whats still accessible of the floor. A change to original plan is to have two attach points that is apart from each other, this makes it more adjustable and stable.
The tubing is 40 mm PUSH-fit pipe used for bathroom sinks etc. 5€ for a meter.
Overall a very light weight solution. Not yet tried it as I’m waiting for the waters to clear from ice but it feels very secure.
I have had similar plans for northern Scandinavia that never left the drawing board (but not in the pile of lost dreams either :)).
I would absolutely go for packrafts and two boats. Using two boats will in my opinion add alto of safety. If one totally breaks down or is lost with combined injury, you can take what is absolutely necessary and continue to safety in one boat and on land, or in worst case leave injured person in a camp and head for help in the remaining boat.
Two boats in the water also means you can give some rescue if one flips, lose his paddle down the stream etc.
I’m quite small and should have taken a single packraft but in greater size for squeezing two persons in if it comes to that and have more room/buoyancy for equipment.
I would only consider kayaks or canoe for flat water were you expect alot of paddling on flat water.
If so, these boats are a bit of a classic choice here in the north https://www.bergans.com/catalog/gear/ally-canoe/allround? , look at the videos of Norwegian adventurer Lars Monsen for inspiration and what the canoe can handle. (He did however go over to packrafts on some of his later hikes and seemed very pleased with them)

I think I will make the next one within a couple of weeks if I can find the time. I will take some better pictures of the process and add some measurements
I will go straight for that when I’m testing, just a little worried that the perfect position will be over the floor/tube joint. But will take that on as it comes, otherwise I guess you could leave a flap from that joint and trim it as an attachment later. But for a first build it might be to tricky for my skill and risk of being the perfect tear point.

I will defently add it after its finished. One downside of it will be that it kind off get in the way of stored gear but i guess it wont be that much of a downside if its located towards the front. I also have to be aware of not interfearing with the tube-floor joint with the bottom attachment (or do an attachment loop upon putting it together).
Yes, I understand that a round pipe shape transforming to a flat in 90 degrees can be tricky and was thinking of making it octagon, square or flat shaped.
I think i will make a classical shaped dry bag for practice, then I can just patch it up later and not let the material and work go to waste
Can you glue an attachment loop to the non-TPU side, or do I have to make the bottom attachment through the tube floor and heat seal on the outside?
Here is an ugly concept sketch for an easier understanding of what I want to do.
