looks like a nice design, simple set up too. I do not see a dagger board, does it have one?

It looks like these are inflatable in the sense that air pressure is used to make the hull more rigid at a reasonable weight. I've thought that pressurized air filled fiberglass hulls could work the same way.

I do not see a dagger board, does it have one?

Yes. Suspended under central tube. You can see it on second foto.

Jonr,

You might be on to something. I've heard some liquid fueled rockets (ICBMs?) relied on pressure from fuel to add strength like a balloon.

What?

Что? Вы думаете, что я говорю по русскии?

As свідомий українець you must use "mova". Something like that:
Що? Я москальську мову не розумію.

When deflated this hulls can be folded or rolled for transportation or storage. Something like red rolls on the picture.

Russian is difficult enough! I will try Ukrainian in 2 years.

So, that tells me you have Ukrainian roots .... Yes?

We cannot live here without some ICBMs in our backyard
Even if we sail multihulls.
Catamaran Prostor - non-licensed Catapult "po russkie". In Soviet times mass produced (several thousands) as by-product by NPO Energomash - one of our main builders of jet-engines for space. Now USA use this engines on first stage of “Atlas” launch-vehicle.

Ha-ha! Study both languages simultaneously, with two pretty teachers. Much more fun

So, that tells me you have Ukrainian roots .... Yes?

No, may be to only slight extent. But almost every Russian-speaker will understand Ukrainian and vice versa.
My roots are mostly Tartar. But also Russian, Bashkir etc. etc. including my grand-grand-… -grandmother which my grand-grand-… -grandfather had found somewhere in France during Napoleonic wars.
So, as Russian proverb says: “Scratch the Russian and you will find the Tatrar”

 

[El_Guero]

And the Ukrainian ....

In France during the wars .... The West has no idea of Eastern history. It is so much fun being over there. I miss it.

Two pretty teachers .... now that is a great idea!
