GTX50 – A Spirited Double-Shot

GTX50 is the first multi-hull to focus on the desires of traditional monohull owners. Drawing on demands from traditional yacht owners and NISI’s own megayachts, GTX50’s arrival brings unprecedented styling, strength, large social areas, and performance.

Concept and design come from the engineering team at NISI Yachts with naval architecture by Setzer Yacht Architects. Based on established interest from the international yachting community, GTX50 delivers exceptional and efficient offshore performance with unprecedented exterior and interior spaciousness.

Currently, NISI 50 XPRESSO is the only multihull in the motoryacht class with a clean-sheet design dedicated to taking advantage of pod propulsion systems; the 50 XPRESSO is the only multihull that offers pod propulsion in this size range.
