Australia’s full-custom superyacht builder Echo Yachts is set to construct world’s largest sailing catamaran superyacht.

15 March 2024


Australia’s large superyacht builder Echo Yachts has signed a contract for the construction of a full-custom 57-metre, twin-masted catamaran sailing superyacht. The yacht has been commissioned by an experienced private client and will be the world’s largest sail-powered catamaran.

Echo Yachts has teamed up with two renowned sailing and aluminium multihull design firms to deliver the project. An extremely efficient aluminium hull form is complemented by twin masts and sails, accommodating a total sail area of some 1,660 square metres for eco-efficient long-range cruising. Weight reduction, simplicity and ease of operation will further characterise this project.

The renowned Dykstra Naval Architects, of Amsterdam in The Netherlands, are providing the yacht’s exterior styling, layout and naval architecture, with an enviable list of project credentials including their iconic sailing yacht projects such as S/Y Black Pearl and S/Y Hetairos.


Detailed naval architecture and structural design will be performed by Australian firm One2Three Naval Architects, the same aluminium and multihull design experts responsible for the naval architecture of the international award winning 84-metre aluminium trimaran superyacht M/Y White Rabbit delivered in 2018, and 56-metre catamaran superyacht M/Y Charley 2 delivered in 2023.

This new large-scale catamaran sailing yacht project sees Echo Yachts expand on their proven large-custom motor yacht capabilities by entering the large-custom sailing yacht market. Further updates to be provided during the build.

Dykstra Naval Architects CEO and Naval Architect Thys Nikkels said, “We look forward to working with the Owner’s team, Echo Yachts and One2Three on taking the current design concept to the next stage of realization”.

Mark Stothard, Echo Yachts Owner and Director added, “Echo Yachts is extremely excited and proud to have been selected to custom build this magnificent catamaran sailing superyacht, and look forward to bringing the yacht to fruition with our Client, Dykstra and One2Three.
