When looking for inspiration for their 66-meter, fossil-free yacht concept, Dutch studio Vripack used creatures like birds and sharks as their source. More specifically, they studied how they’re able to propel themselves through the air and water with seemingly no effort at all. “That’s the beauty of naval architecture,” said Vripack co-creative director Marnix Hoekstra. “First and foremost, you should mimic nature in the sense that you use as little energy as possible when crossing through the waves. We were driven by that goal from the outset.” The resulting design is slender, efficient, and a third of the height of a comparable 66m yacht. With long flowing lines, a cocoon-like superstructure, and a streamlined bow and rounded middle, Futura is meant to share its shape with the whale. Plus, made out of glass, it’s also super light in weight thanks to Vripack’s engineering team that uses “rhombus-shaped framing” in the design, which ends up offering a cross-hatched effect, just like fish scales.
