This 575-Foot Superyacht Has Its Own Helicopter Hangar

If you’re going to name a yacht after a god, it’d better be big. This 575-foot Acionna megayacht, named for a Gallo-Roman water goddess, fits the bill, as it’s even larger than Oceanco’s Aeolus, which derives its title from the Greek god of wind.

The fantastical vessel comes from UK-based designer Andy Waugh, whose Noveau and Epiphany concepts was previously featured on According to his website, he has completed eight superyacht projects as a lead designer, and two more are currently under construction.

Along with its sheer size, the scale of which is shown in stunningly illustrated renders, the first thing that captures the eye is terraced superstructure. Acionna features eight decks altogether, including a double-height main saloon with panoramic curved glass overlooking the main aft deck pool.

That area leads down to a swimming platform, which Waugh describes as a central “island” of communal areas surrounded by the pool and accessed via a tunnel aft and a bridge. As with Noveau, Acionna‘s pool flows down across multiple levels, creating a perpetual waterfall that’s both practical and beautiful. Also aboard is a full-size squash court, helicopter hangar and a 66-foot indoor pool.

Despite its massive stature, Acionna is would ideally be a zero-impact vessel. The only problem is that the technology required for its hydrogen-based propulsion system hasn’t been implemented at this scale.

“She is planned to be powered with hydrogen using a similar system currently being trialed in cruise ships and ferries” Waugh’s website reads. “If the power used to manufacture the hydrogen is purchased from renewable energy sources the yacht could be said to be ‘zero impact.’”

“Until vessels like this one are built there will be no way to increase demand for hydrogen thereby breaking the chicken and egg stalemate of supply and demand.”

Steve Kozloff, designer of the 705-foot-long G-Quest, expressed a similar sentiment in presenting the $1 billion concept, envisioning that it would be powered by the “green fuels of the future”—be it hydrogen, methanol or biodiesel.

“The Acionna concept,” Waugh concludes, ” is for those who see themselves as trend setters and game changers, those who appreciate the zenith of luxury but also want to have a positive impact.”
