First GX42 Merinos Launched Ahead of Monaco Yacht Show Debut

GX Superyachts has launched Merinos, the first 42.1-metre GX42 RPH, in Tuzla, Türkiye. The yacht has completed her initial sea trial and GX now says she has entered final sea trials ahead of her world premiere at the Monaco Yacht Show in September.

A first yacht reaches the water

The launch moves GX Superyachts from a new-brand programme into operation with its first full-scale superyacht afloat. The first GX42 has been under construction at SES Yachts, the Turkish build partner selected for the aluminium programme.

GX introduced the new superyacht brand at the Monaco Yacht Show in 2024 with the first GX42 already in build. Official construction updates documented the hull turn, superstructure joining, outfitting programme and factory testing of the hybrid propulsion system, while the latest GX press material confirms the yacht is now progressing through final sea trials.

Hybrid propulsion, solar generation and battery capacity

Merinos measures 42.1 metres overall with an 8.5-metre beam and 1.9-metre draught. GX Superyachts gives the Raised Pilot House version a volume of 353 GT, a maximum speed of 16 knots and a cruising speed of 12 knots.

The platform uses an advanced parallel diesel-electric hybrid propulsion system together with integrated solar generation and a large-capacity lithium battery bank. Up to 27kW of solar panels are integrated into the RPH hardtop, supporting operating modes intended to reduce generator use and permit zero-emission hotel loads at anchor.

GX says the yacht can operate in zero-emissions mode for up to 48 hours at anchor and can reduce onboard electricity consumption by up to 45 percent. The company presents those figures as part of a broader effort to reduce fuel use and operational emissions while also cutting noise and vibration for guests on board.

Designed around extended family cruising

Marco Casali of Too Design is responsible for the exterior and interior design, while NAMES by Francesco Rogantin developed the naval architecture. The RPH arrangement combines a low exterior profile with substantial internal volume, a large upper deck and an aft beach-club area close to the water.

The main-deck owner's suite includes access to a private foredeck terrace, while the lower deck provides a full-beam VIP suite and three additional guest cabins. GX has described the interior as a family-focused environment using walnut, white leather, lacquered surfaces, stone and softly curved architectural details for longer periods on board.

Monaco world premiere next

The Monaco Yacht Show runs at Port Hercule from 23 to 26 September 2026, where GX Superyachts is confirmed among the exhibiting shipyards. The show's official 2026 fleet information identifies Merinos at 42.05 metres among the yachts delivering this year.

Yard owner Vladimir Zinchenko describes the launch as proof that the concept introduced in Monaco two years ago has become a physical yacht, while CCO Maurizio Magri emphasizes the link between lower generator reliance and onboard comfort. The Monaco debut will provide the first public opportunity to assess the GX42's hybrid, solar and family-cruising concept as a completed yacht rather than a construction project or rendering.
