A fellow named Erik discovered a new small tri design in France called the Kanka 14. He shared via email…
I am writing to make you aware of the Kanka 14 – a collapsable trimaran:

I have been in contact with the designer, and drawings may be purchased.
I’m not aware of any details about this boat beyond what is on the webpage linked to above. But according to Erik, the boat may be built in either plywood or bio-composite.
