 
The newly designed hull—featuring a broader transom and raised soft chines—enhances the X4³’s stability and performance. The added form stability is immediately apparent, and the reduced wake and minimal turbulence from the heeled transom make for a noticeably smoother ride.
At the helm, sailors enjoy a precise, responsive feel. Thanks to subtle adjustments in the new rudder design—now unified across the entire Pure X range—steering the X4³ delivers an exceptional experience for owners.
Additionally, X-Yachts offers a user-friendly online configurator for every Pure X model, allowing you to personalize your dream sail yacht to your exact preferences.
