40-meter-long domus trimaran concept aspires to be the first truly zero-emission superyacht

domus trimaran by Van Geest and Rob Doyle

Designers Van Geest and Rob Doyle introduce ‘Domus Trimaran’, an impressive 40-meter-long zero-emission yacht of 750 gross tonnage. The unique vessel presents an optimized combination of solar power, hydro regeneration & hydrogen fuel cell systems, offering an unlimited range and noiseless, carbon-free cruising. Prioritizing speed, space, and sustainability, the Domus concept aspires to become the first-ever truly zero-emissions superyacht.

bungalow-like interiors

For Domus Trimaran, Van Geest (see more here) and Rob Doyle (see more here) have designed a spacious interior of 780 sqm. In addition to the large internal spaces, the superyacht features multiple covered exterior areas, while also allocating all main guest areas on one deck without steps. In this way, Domus generates a unique villa/bungalow-like onboard experience.

The designers have looked at the Domus design from an architectural point of view. ‘Family life in a way is about protection. So why not build around that, create the protected spaces and maximize the functions of the space available in this one-level setup.’ they explain. All spaces are strategically laid out, to enjoy outside views and maintain a connection with what is happening but, at the same time, they are all connected to the communal exterior and interior spaces.

the large top deck of Domus allows for solar panels to supply the battery bank with all the necessary energy during the night

starting from ‘why not?’

The idea for the Domus Trimaran concept started from a simple question: Why Not? ‘Just because superyachts are what they are now, it does not mean they should stay this way.(…) We were constantly looking at every aspect of the design and saying, ‘I know we do it this way normally but is there a better way?’ the designers share. ‘Therefore, we truly believe that this project will redefine what a multi-hull sailing Superyacht can be.’ they add.

After calculating the smallest vessel size that can host a one-floor layout without it being too bulky, the designers started forming Domus as an amalgamation of different innovative ideas. Rob Doyle Design focused on naval architecture, performance, and structural feasibilities, while Van Geest Design developed the styling and layouts.

to reduce drag and improve speeds, Domus will be able to heel at an angle of two degrees

speeds of in the mid 20s (knots) are foreseen to easily be reached by sailing

the combination of solar power, hydro-regeneration technology, and hydrogen fuel cells gives Domus unlimited range with zero emissions

Domus aims to become the first truly zero-emission yacht with over 750 gross tonnes

louvre styled openings above the courtyards and large windows are spread out on the top deck

while sailing, the windward hull will come out of the water reducing the drag through the water resulting in more speed

the word Domus means a single-story house built around an atrium, with many rooms opening up off the central atrium

the interior features four guest cabins with two sizeable suites each equipped with its own lounge areas

amenities include a cinema room, gym, and a bar, as well as a spa area with a swimming pool
