The purpose of this project is to design and mass-produce kits for a floating tiny house that can sail. It combines high-tech modeling and fabrication and low-tech assembly that can be carried out DIY-style on a riverbank or a beach. This boat is a 3-bedroom with a kitchen, a sauna and a dining room. The deck is big enough to throw dance parties. It can be used as a river boat, a canal boat or even a beach house. Oh, and it's rugged and stable enough to take out on the ocean. Kits will start at around $50k (USD). The design has been tested in simulation and prototype; full-scale production will begin next year.

Prince Kropotkin is for sale!

I am selling my sailboat in preparation for building the first Quidnon. It's a proven and capable ocean cruiser set up for living aboard, either at a marina, at a mooring or anchor, for coastal cruising and for the open ocean. It's in good condition, carefully maintained, reasonably priced at 28,500 USD and is a turnkey solution for someone who wants to live aboard and cruise around. Here is the full listing with all the details. If you are interested, please contact the broker, Capt. Mark Covington.


  1. Dmitry,,,
    Great listing of what seems to be a well-sorted-out and very capable vessel. It seems to be a great value for the price. GLWTS of it.
    It is precisely the listing many of us are waiting for, only for the similarly kitted-up and ready-to-go Quidnon.
    Any idea on when a similarly-complete Quidnon listing might be seen?
    I, for one, can't wait.
    Best wishes,,,locojhon

    1. It depends, among other things, on how well this boat sells. And then it depends on how many people buy and build the kit, and outfit it as well as this boat, and then want to sell it. In short, it all depends on you.

  2. I am super excited to have a Quidnon built. I hope you have been able to progress on building the first full-scale version. I have a few questions about it.

    1. Will you make plan available as well as kits? I live in Vancouver and there are plenty of shipbuilders here, as well as wood. It seems a waste to CNC cut all the wood on the east coast just to ship it all the way here.

    2. I am assuming that the Quidnon will be amenable to traditional ship-building as an alternative to the DIY kit, is there any reason why that assumption would be wrong?

    3. When you are aiming for a $50K kit, is that just for the shell of the boat? What would be included? Roughly how much would a fully-equipped boat be (beds, sauna, engine, etc.)?

    4. A three-bedroom house in Vancouver can run you $2 million, so I can see how these could become seriously popular. If there is enough demand for Quidnons would you consider licensing the design for building them as a business, like a franchise?


    Kind regards,


    1. I am glad you like our design. We are working diligently on completing it and making kits available. Here are the answers to your questions.

      1. There will be study plans available. We will NC-mill kits wherever it is most cost-effective to do so and ship them to anywhere in the world for assembly. We may also decide to make g-code available, which will allow people to do their own NC-milling.

      2. I don't know what you mean by "traditional shipbuilding." Quarter-sawn old-growth hardwood timbers? If so, the answer is no. Quidnon is designed to be built out of milled plywood panels and fiberglassed.

      3. The $50k is just a ballpark number based on rough estimates. Since then it turned out that marine plywood prices in other parts of the world are 1/8 to 1/10 of what they are in the US and Canada, making the idea of milling out kits in North America a silly idea. The actual kit price could be substantially lower.

      4. We will certainly consider all promising ideas for Quidnon-related businesses.
