After 5 years in the making, the somewhat futuristic looking powered trimaran Adastra has been launched in to a muddy backwater of the River Pearl outside the shed where she was built in Zhuhai, China.

Delays in the construction of complex glass structures lay at the route of a delay, which had postponed the launch.  Reported to have cost just £9 million to construct this cut-price superyacht has an eyecatching feel about her

Described by others in the media as “one of the world’s most amazing super yachts, that could spell the future for efficient long range cruising” this 46 metre trimaran has also been described as what Batman would ask for if he purchased a super yacht. The name Adastra, a phrase from Latin meaning “to the stars” suggests that Superman and maybe even Flash Gordon would be equally at home with the choice

Working to the requirements of owners Anto and Elaine Marden from Hong Kong, designer John Shuttleworth working with his two son’s Orion and Sky have created a craft that meets the needs of this very experienced ocean voyaging couple and their family.

Marden, who made his money in shipping called for a high level of design comfort and superyacht style and no effort has been spared to produce a beautiful yacht that will have low fuel consumption and yet provide excellent sea keeping qualities and luxurious accommodation.  He plans to use it to cruise to and between islands he owns off the coast of Indonesia

Multihull specialist, John Shuttleworth is based in West Sussex, England. He has gained a reputation for designing fast, strong, and safe boats. In the 1980’s John Shuttleworth Yacht Designs Ltd., developed the concept of what he calls Integrated Structure. This results in boats that are lighter, stiffer, and stronger than previous multihull designs. 

Built by McConaghy Boats using Carbon fibre with Nomex honeycomb core to construct the superstructure the hull is Glass and Kevlar foam sandwich. 

The interior design is from Jepsen Designs a well-established architectural and interior design firm in Hong Kong.  They have created a spacious saloon area on the main deck, which will undoubtedly offer superb views through a panoramic window and accommodates a lounge area, dining table, and navigation station.

The yachts exterior has plenty of recreational spaces.  A forward facing door through the saloon window gives easy access to a large sunbed on the foredeck.

The aft deck has a sofa and bar area to port and a dining area to starboard, further aft of this there is space for a 4.9 metre tender and directly below is a garage which can store a 3.1 metre tender. The garage door has been designed to fold out and create a large dive platform.

Extra space has been created below deck by slightly flaring the central hull just above the waterline. This area has been split into two sections with a full-width master cabin located aft with access from the deck saloon, and two further guest cabins, accommodation for the crew, and the galley located forward of the engine compartment.

Flying the flag of Hong Kong, Adastra offers comfortable accommodation for nine guests and up to six crewmembers. The main helm station, which has seating for two, is positioned in a raised pilothouse situated between the aft deck and the saloon area and forms part of the cross beam structure.

Controlled remotely using an iPad, the integrated ships monitoring system that monitors fuel, security, pump sensors, electrical and lights has been supplied and installed by SiMON. The vessel has a fully automated fuel management system, which includes an Alfa Laval system for cleaning the fuel.

Some things can be considered difficult when designing trimarans.  Perhaps the most obvious is where do you put the engines.  Here they have opted to put the single main engine in the main hull and rather cleverly have added small 100 hp diesel engines in each of the outriggers that in turn each drive one of the yachts three generators.
