This stationary houseboat was designed in 1966. She is constructed of fiberglass. It's an interesting concept. The design was inspired by some sketches prepared for the owner by the famous French architect Jacques Couëlle. Here are are few of the conceptual sketches.
Here is the general arrangement and construction plan for the final design.
The boat was built by Campania de Navegacion Passat of Panama but we have no idea where she made her home. I do plan to keep an eye out for her the next time I am walking along the Seine River in Paris.
