Sirena Launches Its Largest Yacht Yet Ahead of Monaco Debut
3 min
The first Sirena 42M has entered the water, combining Luca Vallebona’s exterior design, Van Oossanen naval architecture and interiors by Hot Lab.
For a yacht builder, launching a new flagship is more than adding metres. It requires different engineering, supplier coordination, owner expectations and operational thinking. Sirena Yachts has now crossed that threshold with the first 42-metre model in its larger superyacht range.
The Sirena 42M is the Turkish yard’s largest yacht to date and the first completed model from a family also conceived at 35 and 50 metres. Construction began in late 2023, with hull and superstructure joined in February 2025. The first yacht was sold through Sirena’s in-house team and is scheduled to appear at the Monaco Yacht Show.
Exterior design is by Luca Vallebona, with naval architecture by Van Oossanen Naval Architects and detailed engineering by Eureka. The combination places efficient hull development beneath an exterior intended to deliver generous usable deck areas rather than relying on size alone.
Inside, Hot Lab, part of The Viken Group, has developed an organic design language. That description typically signals rounded forms, natural materials and fewer hard visual transitions between rooms. The effectiveness will be easier to judge when completed photography and onboard access replace renders, but the approach suits the current movement towards calmer, residential yacht interiors.
At 42 metres, owner experience becomes inseparable from crew operation. Buyers should examine crew circulation, galley logistics, storage, engine-room access, tender handling and noise isolation alongside the guest spaces. A successful yacht must make hospitality appear effortless because the technical and service plan is working invisibly beneath it.
The Monaco debut will be important for Sirena. It places the 42M in front of brokers, owners and advisers comparing it with established European yards in the same bracket. Build quality, systems access and finish consistency will matter as much as the silhouette.
The first launch also creates a reference point for the wider range. If the 42M performs well in use, it can give credibility to both smaller and larger Sirena superyacht proposals. A flagship’s job is therefore not simply to impress its owner; it must demonstrate what the yard can reliably deliver next.

Tesla’s new Roadster used suction technology and SpaceX-derived thrusters to jump and flip—but production, price and road legality remain unresolved.

Tesla has finally revealed its radically redesigned Roadster—and delivered the airborne spectacle Elon Musk has been promising for years.
Unveiled at a SpaceX testing facility near Waco, Texas, the new electric supercar drove onto a steeply curved ramp, used a suction system to cling to its underside and launched into the air. Cold-gas thrusters stabilised the vehicle as it rotated and returned to the ground.
In another demonstration, the Roadster cleared a line of Tesla vehicles that included a Semi, Cybertruck, Cybercab, Model Y and Model 3.
It was an extraordinary stunt. Whether it proved Tesla has created a genuine flying car is another matter.
The vehicle did not demonstrate sustained, controlled flight of the kind associated with an aircraft or electric vertical take-off and landing vehicle. Its thrusters instead produced brief powered leaps, rotation and landing control.
“We’re not talking about sustained flight,” Smithsonian National Air and Space Museum curator Roger Connor told CNN. “We are literally talking about hopping.”
How does it work?
Tesla has outlined three intended Roadster configurations.
The two-seat Performance model is the comparatively conventional version, although little about it sounds ordinary. It uses active aerodynamics and what Tesla calls a multi-mode suction system to increase downforce and allow the car to adhere to steep or inverted surfaces.
The two-seat Thrust adds rear-mounted cold-gas thrusters, designed to deliver acceleration from zero to 60mph—approximately 97km/h—in less than one second.
At the top is the single-seat Rocket, equipped with 10 thrusters positioned around the vehicle. This is the version intended to perform the airborne manoeuvres demonstrated in Texas.
Tesla engineering vice-president Lars Moravy said the system uses approximately 600 litres of compressed air. Carbon-fibre-wrapped pressure vessels occupy available spaces throughout the car, supplying the thrusters used for acceleration, lift and directional control.
The technology is more closely related to a rocket reaction-control system than a conventional flying-car powertrain. Rather than producing continuous lift through wings or propellers, it releases highly pressurised gas to generate short bursts of thrust.
Tesla says all three versions will offer approximately 300 miles—or 483 kilometres—of driving range and a top speed exceeding 230mph, equivalent to about 370km/h.
These remain company claims rather than independently verified production specifications.
Can buyers order one?
Reservations have reopened in selected markets. According to reporting from the launch, Tesla is seeking US$50,000 to reserve the Performance variant and US$250,000 for the Thrust. Access to the Rocket is described as invitation-only.
No final purchase price was announced, and Tesla has not confirmed Australian pricing, delivery timing or regulatory approval.
Musk said production would begin in 2028. That should be treated as an ambition rather than a settled delivery date.
The second-generation Roadster was originally unveiled in 2017 and was expected to reach customers within several years. The program was subsequently delayed in 2020, 2021, 2023 and 2024. Some customers have consequently held substantial reservations for close to a decade.
There are also formidable regulatory questions. A road-registered vehicle capable of deliberately leaving the ground, rotating and landing among other traffic does not fit neatly within existing vehicle standards. Its compressed-air system, pressure vessels and unconventional manoeuvres would require extensive safety assessment.
The more plausible outcome is that Tesla produces the Performance and perhaps Thrust versions for road and track use, while tightly restricting the Rocket’s airborne functions—or reserving them for controlled environments.
Tesla has produced a genuine moving prototype capable of remarkable stunts. It has not yet demonstrated that customers will be permitted to repeat them on public roads.
For now, the Roadster is real enough to jump. Whether it becomes a car people can buy, register and use as demonstrated remains the more consequential test.
