Radical zero-emission 30m catamaran Domus Cat revealed

Van Geest Design and Rob Doyle Design have teamed up to present a new 30-metre concept catamaran with a 16.3-metre beam called Domus Cat. Following a positive market response from the Domus trimaran concept, the new superyacht design aims to offer the same volumes of interior space combined with zero-emission cruising thanks to a combination of solar power, hydro regeneration and fuel cell technology.

The design studios claim the Domus Cat will have the equivalent floor space of traditional monohull motor yachts of 40 - 45 metres in length and the twin-hull design will allow it to sail at very low heel angles, improving guest comfort and reducing the chance of motion sickness.

Design studios Rob Doyle and Van Geest have been involved in the styling, architecture and engineering of more than 60 superyachts, and have drawn this experience into the Domus Cat. 

"We studied what would be the smallest size vessel we could design with the one-floor layout without making it look too bulky," the designers said in a joint statement. "While Rob Doyle Design has been focusing on the naval architecture, performance, and structural feasibilities Van Geest Design developed the styling and layouts."

The structure of the yacht allows the catamaran to have a far larger beam than other catamarans on the market while also allowing for different styling options, according to the studio. Alongside space for solar panels, the exposed upper deck area is dedicated to liveable space, with various seating and lounging areas both in the shade and in the sun, plus a Jacuzzi.

Inside, the catamaran is home to a "villa style" single-deck living space, with two solar-panelled louvred areas that can be opened or closed to provide light and airflow. A covered aft deck creates a waterfront relaxation area complete with two side balconies. 

Interior social spaces include a dining area, lounge space and seating space. Stairs give access to the accommodations in the hulls and an internal wheelhouse is located on the centreline with direct access to the "space deck" above.

The portside hull houses the complete crew, galley, mess, services and ample technical and storage areas. The starboard side hull houses additional guest cabins and other service areas. In total, the interior covers 224 square metres.
