The 40m trimaran concept aims to be the first zero-emission superyacht

Rob Doyle is part of the new generation of yacht designers tackling the modern challenges of the large yacht industry. With a solid 20-year career path in the large yacht business, he and Van Geest Design came together to present a 40-meter sailing catamaran – Domus. With an interior volume that rivals a 60 meter motor yacht, she aims to do eco-responsible cruising and become the first “zero emission” yacht over 750 GT.

“Just because superyachts are what they are today doesn’t mean they have to stay that way. We were constantly looking at every aspect of the design and wondering ‘is there a better way? We truly believe this project will redefine what a multihull sailing superyacht can be,” say the designers.

Domus, i.e. a one-storey house built around a Latin atrium, the yacht is 35 m wide and has an interior space of 780 m², all on one deck. The craft borrows aspects of this design to create an elevated and open feel on board. Rob Doyle and Van Geest Design have done extensive research into the practicalities and safety features associated with trimarans.

The trimaran is spread over two decks. She can accommodate 12 guests in six guest cabins, with four VIPs and two full-size owner suites, each equipped with its own lounge area. There is a bar in the main lounge. Other amenities include a cinema room, gym and lounge. Domus also has a spa area with swimming pool, making trimaran fun and excitement.

To help reduce drag and improve speeds, it can heel to a two-degree angle. It will also ensure comfortable cruising with minimal rolling. Domus is designed with a focus on performance. “The unique design combination of solar power, hydro-regeneration technology and hydrogen fuel cells gives Domus unlimited range with zero emissions,” the design team said. The trimarans powers during daylight hours and transfers to the battery system at night. It also means that Domus is completely silent with zero emissions at anchor.

Alongside the 40-meter concept, the designer duo is also working on a larger version of the shipyard idea. “We are convinced that if you want to benefit from the advantages of multihulls over 40 meters in size, the only practical solution is a trimaran,” added the design team.

Compared to catamarans, trimarans offer lower costs. Domus has all the systems and engineering in the center hull, just like a standard build to keep things simple. The main hull takes all the rigging forces, thus keeping the transom structures simpler and generally the overall system being simpler. The team behind Domus have been behind the design of over 60 superyachts and have extensive design experience, knowledge and detailed data, making it easy to complete a gigantic project.
