Commissioned by Kooijman and de Vries, Baron Van Höevell designed the 11-metre tjalk Concordia in 1976. Anyone who looks closely at the lines of this yacht will notice that the characteristic tjalk line is immediately recognisable.
The fact that Van Hoevell managed to capture the tjalk type so well is undoubtedly partly due to the fact that this assignment was preceded by various other experiences with tjalks, namely various measurements for conversions and for drawing a sail plan for existing ships. The tjalk Concordia was not designed with a so-called bollestal* but with an afterdeck behind the skipper's house with the traditional windows.
* Frisian for the steering cockpit of a vessel, literally translated as the place in the back of a boat where the bull was stabled.
