Echo Yachts has launched its 84 metre trimaran motor yacht White Rabbit, which is now the world's largest tri-hulled superyacht.
The yacht was launched from BAE Systems' Henderson based facility in "perfect" weather conditions on September 1.
She will now be "extensively" sea trialled off the West Australian coast before her delivery, which is due to take place by the end of October.
The launch comes after the yacht was unveiled at an event held at the Australian based yard last month. The evening included VIP speeches, video documentary of the build and a sound and light show.
Guests were given the opportunity to step on board and view some of White Rabbit's exterior entertainment spaces. The event was attended by the owner and family.
White Rabbit is the biggest superyacht ever built in the country and will be delivered to an experienced owner who owns a number of other multihull superyachts.
These include a 51 metre shadow catamaran vessel, also built by the Henderson based yard, which will be used as a support craft for the 84 metre superyacht.
Built in fibreglass with cutting edge vacuum infusion processes and high-tech laminates, the catamaran, named Charley, was designed by LOMOcean in New Zealand to house a fleet of 11 watercraft including a 12 metre catamaran.
Originally intended for a 2017 delivery, the 84 metre trimaran was designed by Sam Sorgiovanni with One2Three developing the naval architecture. White Rabbit will offer huge interior volumes with the ability to accommodate up to 12 guests.
Echo Yachts director Mark Stothard said he was "very proud" of White Rabbit, describing the yacht as a project "many other builders would shy away from."
He added: "We are very grateful to our client for pushing us and backing us all the way in these endeavours. The net result is that the yacht we are about to hand over is truly world class and a credit to everyone involved."
Designer Sam Sorgiovanni added: "There is a great sense of pride that comes from seeing the launch of White Rabbit. It’s not just the time that it took to build the yacht but more so from history and the fact that my career started here and with many of the people involved in the project."
