The Monaco Yacht Show is the premier venue for new large-yacht debuts. Among the introductions at this year’s show was a new brand called GX Superyachts. GX will offer a range of 24-meter to 56-meter (78-164 foot) aluminum vessels that will combine high levels of luxury with respect for the planet, according to the company. The first 42-meter (138-foot) model is already in build.

GX Superyachts is the brainchild of the team behind Greenline Yachts, which has been producing hybrid yachts up to 58 feet for more than 15 years. Taking their experience with cutting-edge hybrid propulsion, smart hull design and solar charging, they have made the next step by addressing their vision to the superyacht sector.

The result is a line-up of custom yachts that offer what they call “seductive design and extraordinary comfort for the true yachting lifestyle.” The new brand embraces Greenline’s core principle of responsible yachting. The new range centers on Greenline’s unique serial hybrid drive and powerful solar arrays, which form part of the structure of the yacht.

“Our journey started with Greenline Yachts, where we pioneered the world’s first serial production hybrid yacht over 10 meters back in 2008,” said yard owner Vladimir Zinchenko. “With more than 1,000 yachts delivered globally, Greenline has been at the forefront of innovation in the boating industry. Throughout that time, we have tried to further our vision of responsible yachting, from sourcing raw materials right through to the operation of the yacht itself.”

GX Superyachts has appointed Andrea Armas as consultant to the Board of Directors. A naval architect and marine engineer specializing in yacht building supervision, Armas is a seasoned professional with 28 years of experience as an owner’s representative for major international shipyards, to serve as an advisor to the Board.

“I am backing GX Superyachts because I admire their ambition and vision,” he says. “My goal is to help the team translate their decade-long experience in hybrid recreational boatbuilding into the highly regulated superyacht sector.”

Royal Inspiration

The idea of broadening Greenline’s commercial and environmental success into the superyacht sector was born at a previous edition of the Monaco Yacht Show in 2018. Greenline’s all-electric 9.99-meter yacht caught the eye of His Serene Highness Prince Albert II of Monaco, who requested an escort to the Monaco Yacht Club in the boat.

“Each yacht in our GX Superyacht range is equipped with our innovative hybrid propulsion system, allowing for both efficient electric cruising and powerful diesel performance when needed,” explained Chief Commercial Officer Luca Raumland. “At 6 knots in electric mode, these yachts can achieve an incredible range of up to 100 nautical miles. In diesel mode, they can cross the Atlantic at 12 knots, while the max range is 11,571 nautical miles at 6 knots”

When compared to a conventional yacht, the GX range will have less than 40 percent of the carbon emissions, the company says. The exceptionally lower emissions are important, but it is not the whole story. Like Greenline Yachts, GX Superyachts are designed with an extensive solar array and a large lithium battery bank, which together mean that the boat can lie silently at anchor for 48 hours or more. During that time, full hotel systems including air conditioning run off the batteries without the need to fire up a generator. The result is no noise, vibration or smell from combustion.

GX42 in Build

The first customer to sign up for a GX Superyacht came through the Greenline network, the company says. Construction on the first GX42 is under way with the keel laying ceremony on June 1 of this year. As of early Fall, more than 50 percent of the hull was already welded. Delivery is slated for summer 2026.

One of the biggest decisions for the team behind GX Superyachts was where to build the new range. Greenline specializes in composite construction, with facilities in Slovenia that can accommodate yachts up to 24 meters in length. It had to find a partner for larger aluminum yachts. From more than 20 shortlisted yards, GX signed with custom specialist SES Yachts of Tuzla, Turkey.

“There’s no better time to launch this project than now, as we mark the 50th anniversary of our activity,” said Elif Yıldırım, Managing Partner of SES. “We embrace custom and semi-custom projects, and the new GX Superyachts range plays perfectly to the skills we have in house. What’s more, we understand and share the principles behind the brand, being a family-owned business ourselves and just as concerned about sustainability. Collaboration on the first model has been very smooth, and we are looking forward to building more yachts with GX.”

Design in the Foreground

Marco Casali is responsible for the sleek exterior lines of the new range, which unites an efficient low-profile superstructure with exceptional interior volumes. Two variants of each model are available. The Coupé has a long, curved superstructure roofed with solar panels, which slide apart to reveal a large hidden sun deck equipped with Jacuzzi and bar. The RPH version offers a large flybridge with a modern aesthetic and 353 gross tons of volume. Both have a beach club that has fold-down wings and a hydraulic platform.

Casali also designed an interior that delivers on the promises of those lines and creates a single, coherent whole. Passing from the generous aft decks into the main salon or the flybridge are meant to feel like a natural, harmonious progression. His vision for the styling of the first GX42 draws on some of the finest specialized brands in the world. For instance, the yacht’s bathrooms are fitted with Antonio Lupi porcelainware and Dornbracht faucets. Loose furniture comes from Poltrona Frau and Rugiano, while exquisite Foglizzo leathers and natural wood flooring by Cadorin also feature.

“Our studio has long worked with Greenline Yachts, so we understood exactly what the new GX Superyachts brief required,” said Casali, founder of Too Design. “I am proud of the way we have reinterpreted the timeless looks of the smaller yachts to give soul and purpose to the lines of the new superyachts. And it is a real pleasure to be responsible for both the exterior and the interior, which results in a really harmonious finish. The challenge around sustainability is particularly close to my heart.”

On the technical side, Francesco Rogantin of NAMES studio has drawn an underwater hull that maximizes stability, as well as speed potential. Powerful software and smart design have optimized the long, slim hull to offer multiple points of efficiency between maximum and cruising speeds.

“It felt like a very natural partnership with GX Superyachts, who knew exactly what they wanted: a hyper-efficient and stable displacement hull,” says Rogantin. “The challenge was to analyze the different operational scenarios and ensure that the hull and appendages performed to their best for each one. We deployed a powerful suite of tools to achieve this.”
