Cynthesis 180: Alexandre Thiriat reveals 58.3m power catamaran concept

25 February 2022 • Written by Olivia Michel

Design details and renderings have been revealed of a new 58.3 metre eco-conscious catamaran concept, that has been developed together with a “well-known German shipyard,” according to the design team.

The Cynthesis 180 project is the result of a collaboration between Alexandre Thiriat, an experienced designer best known for his interior work on superyachts including Axioma and Alfa Nero and a BOAT International Design & Innovations Awards judge, together with exterior designer Christian Leyk of Coquine design studio, with input from a team of experienced brokers, owners and builders. Preliminary architecture is by Nicolas Fauroux, who also studied foils to increase hull efficiency.

The concept offers a variety of vibrant colour schemes

The Cynthesis 180 will be constructed in steel and aluminium with recyclable materials used to reduce footprint. For significantly reduced or emissions-free operations, owners will have the choice of two Siemens electric motors (600kW or 800 kW) combined with either two IMO Tier III-compliant generators or two zero-CO2 hydrogen generators (currently under development), and batteries and solar panels.

“This is the 1.0 version of the catamaran of the future,” commented Thiriat, who has previously developed a hydrogen concept catamaran named Corellian. “We are 10 metres more than the largest catamarans currently under production and of course, the style and layout can be customized to suit clients.”

The project is reportedly set to be built by a "well-known German shipyard"

“The hydrogen generators are promising and will fit in a footprint identical to classic generators,” added Thiriat.

Compared to a 60 metre monohull, the designers have claimed that the catamaran design of the Cynthesis 180 also offers 30% more room for lounge and dining spaces, 80% more space in guest cabins, double the area in the owner’s suite and 150% more outdoor space. An interior volume of 1,600 GT will provide accommodations for up to 12 guests and 18 crew.

At the same time, a shallow draft of 2.3 metres allows the yacht to cruise in regions such as The Bahamas, which are off-limit to yachts with deeper drafts.

Owners can chose from an emissions-free propulsion package to reduce their footprint

On board highlights will include a double-height mezzanine main saloon spanning just over 50 square metres, a D11-capable helipad and storage for two tenders and four Jet Skis. There is also room for a total of three pool areas, comprising two pools forward and aft on the dedicated owner’s deck plus a third hot tub on the sundeck. 

The model is finished with a colourful superstructure, with owners able to choose from a range of shades to complete the look.
