Groundbreaking 40m zero-emission trimaran concept Domus unveiled

Rob Doyle Design and Van Geest Design have collaborated to present Domus, a 40 metre sailing catamaran with interior volume that rivals a 60 metre motor yacht.

With speed, space and eco-conscious cruising at the forefront of the design, Domus aims to become to the first truly zero-emission yacht over 750 gross tonnes.



“The uniquely designed combination of solar power, hydro-regeneration technology and hydrogen fuel cells gives Domus unlimited range with zero emissions,” the design team said.

“An optimised system of solar power and battery storage allows the yacht to motor during daylight hours and then transfer over to the battery system at night. This also means that Domus is fully silent with zero emissions while at anchor.”

Alongside veritable eco-credentials, Domus has been designed with performance in mind. To reduce drag and improve speeds, it will be able to heel at an angle of two degrees. This will also ensure a comfortable cruise with minimal rolling.



The yacht’s interior space covers 783 square metres split between two decks. There are six guest cabins in total, with four VIPs and two sizeable owner’s suites each equipped with their own lounge area.

Amenities include a cinema room, gym and saloon with a bar. Domus also hosts a spa area with a swimming pool.



The word Domus means a single-storey house built around an atrium, with many rooms opening up off the central atrium. The yacht borrows aspects of this design to create a lofty, open feeling on board.

Working together on the project, Rob Doyle and Van Geest Design have done extensive research into the practicalities and safety elements associated with trimarans. “We strongly believe if you want the benefits of multihulls at a 40-metre-plus size the only practical solution is a trimaran," the design team added.

“Just because superyachts are what they are now, does not mean they should stay this way. We were constantly looking at every aspect of the design and saying, 'is there a better way'? We truly believe that this project will redefine what a multi-hull sailing superyacht can be."

Alongside the 40 metre concept, the design duo are working on a larger version of the concept for a shipyard.
