A new design of superyacht will see a combination of hybrid propulsion and solar panels for minimal environmental impact and high-energy efficiency.

The concept is built around a 60-metre long catamaran with capacity for up to 36 passengers.

The level of sustainability will enabe the new generation vessel to access to harbours that would otherwise be closed to large motor yachts, according to developer, smart technologies firm Wärtsilä and yacht designer Stefano Pastrovich.

The new generation “cost optimised” vessels will serve the charter and luxury hotel sectors.

Wärtsilä Italia senior sales manager Giammario Meloni said: “Efficiency and environmental performance are key pillars of Wärtsilä’s Smart Marine approach, which emphasises the need to collaborate with world-class partners.

“This project encompasses all these ambitions, and we look forward to co-developing with Stefano Pastrovich a totally integrated solution that combines energy efficiency, sustainability and onboard comfort.”

Pastrovich added: “Wärtsilä is the ideal partner for this project, since we share a vision to be the very best at what we do. Bringing together our architectural and marine technology know-how will create a mega-yacht design on the leading edge of innovation.

“I’m convinced boutique cruise ships of this calibre could spark a turning point in the charter market, attracting a new customer base of millennials and cruise veterans.”
