Instead of enjoying the last warm days of the year, I have to stay indoors and swallow aspirin. Kismet! I hope I can use at least the beginning of next week, when it is supposed to be relatively warm. It seems that the next days like this will not be for half a year or even longer!!!

Indeed, I have heard something about the "skin on frame" technology. I even watched this film once.
I found a supplier of materials in Poland
and another designer and probably a supplier (in Germany). There is also a project of a slightly larger boat, with a centerboard case, although I like the pram, i.e. Stasha, more.
I don't know if it is possible to combine this material and how to repair any damage.
Maybe it would be possible to find cheaper materials, I haven't looked yet. If the boat (Stasha) were to weigh 10 kg (i.e. halves of about 5 kg), then there really wouldn't be a problem with taking it off the roof rack.
I don't really know how strong the board attachment is. One side (center?)board. Hmm. I sailed with one board, because I happened to lose and sink one, so before I made a new one from an old rudder blade - I sailed with one. It's possible, but still a bit less comfortable.
It would also be good to think about some buoyancy tanks. These could be inflatable tanks, tied to the outside of the sides, or possibly short internal tanks to be attached inside the boat by the sides. You could lean on them while sitting inside.
However, apropos sitting on the bottom – in my boat I usually sit on the bottom (metacenter), but sometimes I have the opportunity to stretch my legs when the wind is not too strong and I do not have to pay attention to ballasting.
The ability to stretch your legs on such a small boat is really important, believe me!
That's why I was thinking about something similar to the Seahopper. There are similar designs for amateur construction. In such a boat, you could even think about a 1-2 day camp with a tent on the boom. My modifications would consist of adding inflatable buoyancy tanks mounted on the outside, and an additional PVC skin on top of all that, which would provide basic waterproofing and extra stiffness.

So as not to tire you - I will end my post here, although I am preparing a further, more detailed part, although I do not have all the details well thought out yet. If I had everything thought out already, I would simply start building right after the season.
