Around the hull of a ship is the waterline, defining the border between what’s under and above the water. The idea of the waterline became the concept to unite also the interior. Throughout the interior everything below this ”waterline” is slightly bleached walnut, everything above is white. This makes for a spatial flow through the four twin-cabins, corridor and the eight metres wide living/dining area – creating a connecting straight horizon line along the otherwise ever-changing room geometry (due to the curvature of the hull).
