New 70-metre trimaran superyacht concept
Wind Motion 70T is a 70-metre trimaran concept by French-based yacht designer Mathis Ruhl. New rigs, developed by a designers are capturing and transforming wind energy into an efficient propulsive force.
Named the RTW ², Ruhl explains: “We previously developed the MRTW rig as a wind propulsor suited for larger vessels. With the RTW ² rig, we took the concept even further, breeding it with the articulated two elements thick wing concept. A larger wing mast section and foldable articulated thick sail reduces the compression load in the mast, and unties the two spars in a central pivot. The result is higher aerodynamic efficiency, a lighter structure, and lower required deck space.”
