The X4³ MkII features a redesigned hull with a wider transom and smoother chines, significantly improving stability while reducing wake and turbulence. At the helm, the sailboat offers precise and responsive handling thanks to a modernized rudder.
The NEW X43 is designed to meet the requirements of the European Recreational Craft Directive (RCD) and complies with Design Category A – “Ocean”.
