Efficiency and Weight
Underwater lines are optimized by Computational Fluid Dynamics (CFD) and towing-tank tests. The lightweight construction is a result of bionic design, the use of carbon fibers and high-quality resins. Interior furniture is made of stiff and lightweight composite plates with real wood-veneer. This reduces the weight significantly to about half the weight of a conventionally constructed and powered yacht. Each kg / pound saved is equivalent to less wave drag and friction and therefore less energy required to move the boat.
Overall, this leads to high levels of efficiency enabling fast and self-sustaining propulsion. Salon and cabins are wrapped in thermal insulation. Furthermore, all windows are shaded by either the roof and/or the hull, thus lowering the energy consumption needed to keep the interior at comfortable temperature levels.
