Hybrid propulsion system passes workshop test on GX Superyachts’ new build

Now that GX Superyachts’ new build hybrid propulsion has passed its workshop tests, the next phases of construction of the flagship 42-metre model will see the finalisation of insulation and piping, continued electrical installation, onboard interior fit-out, and integration of the hybrid propulsion system. The latter, which combines diesel-electric drive with significant solar power generation, recently completed its factory testing phase and is ready for delivery.

“It’s inspiring to witness the GX42 taking shape so smoothly,” says Vladimir Zinchenko, founder and CEO of GX Superyachts. “Each milestone reinforces our belief that the GX42 will set a new benchmark in responsible yachting — a vessel that delivers both elegant design and low-impact cruising.”

With steady progress at SES Yachts’ facilities in Istanbul, Turkey, GX Superyachts says the project is moving confidently through the build schedule and remains on course for delivery in summer 2026.

Since the successful hull turning and superstructure joining earlier this year, the yacht has entered a new phase of outfitting. The aluminium structure is now fully complete.

Inside, thermal insulation is approximately 80 per cent installed, and the main piping systems have also reached 80 per cent completion. Electrical installation has advanced to 25 per cent, and the paint application is 50 per cent finished.

Bespoke interior furniture — shaped by Marco Casali’s design vision — is also progressing well, with 50 per cent of items complete in the workshop.

“Thanks to our partners at SES Yachts, Andrea Armas, Marco Casali and Francesco Rogantin, the project is running smoothly and exceeding expectations,” says Zinchenko.

Sea trials are scheduled for early 2026. “We are pushing the boundary of responsible yachting navigating through a new era of technological advancement, tailoring the dream of yacht owners into a sustainable reality,” concludes Andrea Armas, consultant to the board of directors at GX Superyachts.
