Aera Concept: Fighting Emissions with a Giant Sail

Environmental issues and Royal Huisman

It's generally accepted that sailboats are completely environmentally friendly, but in the world of superyachts, things aren't so simple: their carbon footprint remains a sore spot.

Royal Huisman was a pioneer in hybrid superyacht technology. In 2009, the company launched Ethereal, the first such project. But Royal Huisman has no plans to stop there. Last year, they launched the eco-initiative Project Tidal Shift, the culmination of which was the Aera concept—a superyacht as close to zero emissions as possible.

How did the Aera concept begin?

The Aera project is based on the idea of automation. This 50-meter open-deck catamaran with a graceful, flowing profile is propelled by a giant carbon wing sail. The mast is an impressive 35 meters tall. The concept's creators sought to overcome the age-old yachting dilemma of choosing between comfort and control.

"It all started with an idea: we needed a yacht that would be eco-friendly thanks to the power of the wind, but wouldn't require a crowd of sailors to raise the sails," explains Ian Percy, an Olympic champion and America's Cup veteran. His company, Artemis Technologies, is known for creating high-tech sails and foils for elite regattas like SailGP.

What are the features of the Aera sail system?

To create the unique "wing" for the Aera, Artemis engineers worked together with specialists from Rondal, the composite materials division of Royal Huisman. 

The result is a sail with an area of almost 250 square meters. According to Robb Report, "the sail's profile resembles a real airplane wing." This approach is surprisingly efficient: with ten times less air resistance than a conventional mast, the setup produces a power output that would require an area 80% larger than a conventional sail.

Control is as automated as possible: electric motors rotate the mast, and a computer continuously adjusts the angle of attack. Jan Timmerman, CEO of Royal Huisman, explains: "The captain sets the course, presses a button, and within a minute the yacht is flying through the waves. It's no more difficult than navigating a motorboat."

When the wind dies down, Aera switches to electric propulsion: the retractable propellers are powered by a 580 kWh battery. This power reserve is sufficient to provide guests with comfort (air conditioning, lighting, etc.) for 11 hours. At anchor, the hydrogen batteries are activated, providing an additional three days of complete autonomy. And for transoceanic crossings, there are eco-friendly biodiesel generators on board.

Aera's body and interior design

To ensure Aera boasts not only breakthrough technologies but also outstanding design, designer Cor D. Rover envisioned something truly special. This resulted in the concept of an asymmetrical hull with three levels of flowing decks.

This approach resulted in the perfect design for yachtsmen who enjoy open-air relaxation and natural light. Rover says, "The catamaran is inherently stable. Heeling angles are no more than two degrees. And as a bonus, you get simply gigantic decks."

The impressive 14-meter beam creates a feeling of spaciousness and airiness: shaded passageways connect lounge areas with unique, free-form shapes. The open deck area exceeds 670 square meters—a volume typically found on monohull yachts, which are a good 20 meters longer than the Aera.

Luxury is in every detail: the master suite with its private pool and terrace is located on the forward section of the main deck, while the aft deck boasts another pool and a beach club with access to the water. The puzzle of the perfect eco-yacht is almost complete. Only the final piece is missing. "We just need one young tech billionaire to believe in this idea," Rover concludes.
