Step Inside the Adastra Trimaran Yacht

Adastra is one of the world's most recognizable yachts; we invite you for a look inside this amazing vessel.

By Kim Ayling

Despite being first launched almost 10 years ago, the Adastra yacht continues to be a marvel. Built by renowned Australian shipbuilders McConaghy Boats , Adastra’s sleek trimaran design has made her one of the world’s most recognizable yachts; in fact, her striking stature saw designer John Shuttleworth receive a coveted Neptune award for most innovative design at the 2013 World Superyacht Awards.

At 139.5ft, Adastra is a comfortable fit in the superyacht category. However, to keep her as light as possible, her designers and builders undertook a structural analysis of all of her major components with virtually every element custom built. Her three hulls are made of e-glass and Kevlar foam, while her superstructure is constructed from carbon fiber with a Nomex core. This combination of ultra-lightweight materials and careful design means that she remains impressively light despite her size, weighing in at 52 tons.

This steadfast commitment to a lightweight design has ensured that the Adastra yacht has remarkably low fuel consumption – so much so, in fact, that she is capable of crossing the Atlantic Ocean not once but twice before needing to refuel with a max range of 10,000nm, dramatically reducing her environmental impact. Adastra ’s lightness also has a significant impact on her speed, with the eye-catching yacht boasting a top speed of 22.5 knots, and an all-weather cruising speed of around 17 knots.

The unique vessel was originally custom-built at McConaghy’s Chinese shipyard for Hong Kong-based shipping magnate, Anto Marden, who commissioned Adastra as an explorer yacht for himself and his family. And it appears that she has now served Marden’s purpose – in 2022 she was on the lookout for a new owner to continue her adventure (if they had a spare $10m to hand).

It is not just Adastra’s exteriors that are a design marvel. One of the big challenges in building this yacht came from trying to fulfill the owner’s brief for a lightweight ship capable of navigating even the most challenging conditions, while still retaining all of the luxury and onboard comforts expected of a yacht of this size.

As we mentioned above, a custom solution was the only way to guarantee this, with a pared-back yet luxurious finish provided by Jepsen Designs – a Hong Kong-based studio with Danish architect Inge Strompf-Jepsen at its helm. Adastra’s uber-stylish interiors combine Scandi minimalism with uncompromising practicality: honey-colored wood, cool neutral tones and smooth curved lines flow throughout, with flashes of beachy blue completing the aesthetic.

Panoramic views are provided by domed wraparound windows in the main lounge area, with skylights overhead ensuring an abundance of natural light. The design tricks don’t stop there, with the main hull cleverly flared over the water’s edge to secure additional onboard room.

Adastra offers space for up to nine guests: her full-width owner’s cabin sits in a section of the main hull and is accessed via the saloon, with two additional guest cabins (each containing one double and one single bed), as well as room for a five to six-person crew, found forward of the engine room on the lower decks.

As a vessel designed for long journeys around the world, plenty of space to relax on board was essential for Adastra. Her 52.5ft beam allows for a spacious saloon which accommodates a stylishly curved lounge area on a slightly raised section at the fore, as well as a central formal dining area.

From the saloon, stairs at the front of the ship lead to a foredeck with a roomy sunbed, where extra protection from the midday heat can come from a retractable awning. The equally appealing aft deck offers further lounging space, as well as a dining and bar area perfect for al-fresco meals, which can be enjoyed no matter the weather thanks to a hard-top cover.

Adastra’s plentiful outdoor space can be further extended via the garage door, which folds out to create a diving platform. She also offers additional storage capabilities for not one but two tenders, giving her new owner even more scope for onboard adventure.

From the very beginning, Adastra was a yacht built for adventure. Although she was initially commissioned for island hopping around Southeast Asia, where her owner has several private islands, she is truly capable of navigating virtually any of the world’s oceans. Under Marden’s ownership, she has seen many a destination, including the sunny coasts of Europe, the shores of the Caribbean, and everywhere in between.

The Adastra yacht also has an exceptionally shallow draft of just 3.9ft, allowing her to venture into bays and harbors that would be completely off-limits to other ships of her size, making her perfect for isolated island areas. And of course, her remarkably low fuel consumption means she can head into the remotest of regions for extended periods without a worry.

Another of Marden’s priorities when commissioning a custom yacht from McConaghy Boats was seaworthiness; a good-looking vessel that couldn’t perform in all conditions wouldn’t cut it. Adastra’s trimaran design makes her impressively stable and comfortable, no matter the weather – Marden has reported heading out into ferocious gales that no other superyacht could handle. However, while she may be able to handle adverse conditions, her multiple sun decks do make agreeable weather the best way to enjoy this magnificent vessel.

• Boat of the Week: Inside ‘Adastra,’ the Bonkers, Rule-Breaking Trimaran That Has Crisscrossed the Globe

The 140-foot "Adastra"'s triple hulls, light weight and shallow draft gives it exceptional seaworthiness and range. Plus, it looks super cool.

Adastra , or to the stars , as the poet Virgil once said, is not your average superyacht . With its striking spaceship profile, it might look like a concept. Delivered in 2012, this 140-footer has spent nearly a decade exploring the globe.

“We have been lucky enough to spend at least three months on board every year since the build, crossing the Atlantic and Pacific Oceans, and exploring the more traditional cruising grounds of the Mediterranean and Caribbean,” the owner, requesting anonymity, told Robb Report . “ Adastra is a truly stable and safe oceangoing yacht.” It also happens to be one of the most innovative vessels on the water.

British designer John Shuttleworth has won multiple awards, not to mention nonstop praise, for Adastra . What sets the boat apart are its unusual trio of silver hulls that resemble an outrigger canoe. “The structure is a major engineering achievement,” says Shuttleworth in a video describing the design. “Nobody had ever designed or built a boat like that.”

Built by McConaghy Boats in Zhuhai, China, the custom design went through structural analysis, while a computer model of Adastra was tested for wave impact, slamming and the potential durability of the outriggers running through big seas. Constructed from e-glass and Kevlar, these hulls are mated to a carbon-fiber superstructure, so the boat weighs only 49 tons, or the equivalent weight of a 60-foot conventional yacht. Since weight reduction was critical to the trimaran’s performance, McConaghy custom-designed all the components—hatches, port lights, ladders and hinges—to be made of carbon fiber. This lightweight design delivers hydrodynamic efficiency, stability and performance, as well as low fuel consumption and low environmental impact. “It uses a seventh of the amount of fuel” of conventional motor yachts its size,” said Shuttleworth.

“Our hope at the time was that the design would represent consciousness of the environmental issues facing the world, while also giving impetus to changing attitudes towards reducing carbon emissions and fossil fuel consumption,” Shuttleworth told Robb Report .

Adastra has weathered 50-knot storms and boasts a vast 10,000-nautical mile range at 10 knots. Powered by a single 1,150 hp Caterpillar C18 engine, the boat’s top speed is 23 knots, with a friendly cruise of 17 knots. Adastra also has two 110-hp Yanmar outrigger engines to power the three onboard generators. For transoceanic crossings, the two 800-gph water makers keep the 730-gal. freshwater tanks full.

Adastra ’s 3.9-foot draft can get into shallow areas that more traditional yachts can’t access, making her ideal for shallow-water areas like the Bahamas. The yacht also has a custom anchoring system, with three anchors that deploy across the bow, stern and along the main hull.

Despite its eco credentials, Adastra is still very much a luxury yacht. With the main hull flared over the water for additional space, the exterior layout allows guests to enjoy several secluded areas and superb communal spaces. The Scandinavian-influenced interior by Jepsen Designs, is minimalist and dominated by the natural light flowing in from curved, wraparound windows and skylights, highlighting the honey-colored woods and neutral color palette of the open-plan living areas. Adastra was designed for nine guests and up to six crew. The full-beam master cabin is aft, connected directly to the main salon, while two guest cabins and the galley are located near the engine compartment.

Adastra ’s 52.5-foot beam features a spacious aft deck with lounges and a sheltered alfresco dining area, while forward of the main salon, guests can relax on the roomy foredeck, with its large sunbed. The yacht’s garage door folds out to create a diving platform.

ADASTRA Yacht – Exquisite Craftsmanship $10M Superyacht

The ADASTRA yacht is a 42.5-meter unique superyacht built by McConaghy Boats for Hong Kong-based shipping baron Anto Marden in Zhu Hai, China.

She was named after the Latin ‘Ad Astra’ meaning “to the stars” which is truly fitting for a superyacht with a design that is ahead of our times.

She was the product of a five-year collaboration between her owner, naval architects/exterior designer John Shuttleworth Design Ltd , interior designer Jepson Designs, and the shipyard which resulted in a masterpiece. 

The ADASTRA yacht is a stunning trimaran boat with exceptional seakeeping capabilities, elegant accommodations, and minimal fuel usage.

For these reasons and more, she received the 2013 World Superyacht Award for most innovative design. 

ADASTRA yacht interior

Jepsen Designs’ minimalist Scandinavian-inspired design is dominated by natural light streaming in through curving, wraparound windows, and skylights, accentuating the honey-colored timbers and neutral color palette of the open-plan living rooms. 

Adastra can accommodate up to nine guests and six crew members.

The full-beam master suite is aft, directly attached to the main salon, while the galley and two guest rooms are located near the engine compartment.

Specifications

The ADASTRA yacht has a 10,000-nautical-mile range at 10 knots, a top speed of 23 knots, and a comfortable cruise speed of 17 knots. 

She is powered by a single 1,150 horsepower Caterpillar C18 engine and is equipped with two 110-hp Yanmar outrigger engines to power the three onboard generators and two 800-gph water makers to keep the 730-gallon freshwater tanks filled during transoceanic journeys.

Her 3.9-foot draft allows her to approach shallow areas that other yachts cannot, thus making her suitable for shallow-water destinations such as the Bahamas.

She also boasts a unique anchoring mechanism that deploys across the bow, stern, and main hull.

The ADASTRA yacht’s futuristic exterior was penned by Shuttleworth Yacht Designs and features a striking silver design and an unusual trio of hulls that turn heads wherever she goes.

She was built with four key requirements – offshore seaworthiness, comfort, the economy of operation, and a shallow draft.

ADASTRA yacht’s impressive structure is made of carbon fiber with a Nomex honeycomb core, while her three hulls are made from an e-glass and Kevlar foam sandwich. 

Her foredeck boasts of a large sunbed that can be shaded with an awning suspended from carbon-fiber poles set into the deck. 

Accommodation

The ADASTRA yacht has a capacity of 9 passengers and up to 6 crew members. 

The accommodation is located on the lower deck while the two guest cabins, crew accommodation, and the galley are located near the engine compartment.

There is additional space below the deck thanks to the flared center hull, which is above the waterline.

The main deck is home to a saloon, which has a lounge space, dining table, and navigation station, among other things. 

The sunbed is located on the foredeck, while the aft deck contains a lounge and bar area, as well as a dining table and chairs.

Between the saloon and the aft, there is a raised platform with seating.

In the center of this platform lies the pilothouse, which contains the primary helm station that has seating for only two people.

$2M Price Drop on Trimaran Motor Yacht Adastra

The iconic 42.6 metre trimaran Adastra , listed for sale with Burgess , has had a price reduction of $2 million.

Built by McConaghy Boats , she was delivered in 2012 to an experienced yacht owner. The futuristic design was penned by John Shuttleworth with interiors by Jepsen Designs .  Adastra  won a coveted Neptune at the World Superyacht Awards in 2013 for the most innovative yacht.

Made for exploring, an impressive 10,000 nautical mile range means she can cross the Atlantic twice before needing to refuel. A shallow draft of 1.2 metres allows her to access hard to reach anchorages and shallow bays too.

The main saloon benefits from large wrap-around windows, with a door in the centre leading to a large sun bed on the foredeck. This outdoor area can be shaded with an awning suspended from carbon-fibre poles set into the deck.

Below, extra space has been created by flaring the central hull above the waterline.  Adastra  can accommodate up to nine guests in a full-beam master cabin and two doubles, with a crew of six. The master cabin is accessed from the saloon and sits aft in a section of the main hull. The guest cabins are forward of the engine room with crew cabins and the galley further forward still.

Her Scandinavia-meets-Asia style interiors feature light honey oak and semi-gloss white paint with occasional brushed stainless-steel trim. Rooms are finished with white woven fabrics and blue and white soft furnishings.

The main helm station, which has two seats on a plinth that give a view over the cabin top, is in a raised pilothouse between the saloon and the aft deck. Adastra  also has a 4.8 metre tender, a second three-metre tender.

The hulls of the yacht are formed from e-glass/Kevlar foam sandwich, with the deck and superstructure made of carbon fibre and Nomex honeycomb core. Power comes from a single Caterpillar C18 1150hp main engine and two Yanmar 110hp outrigger engines, for a top speed of 23 knots.

Adastra  is now asking $10,000,000.

The future of superyachts is here with Adastra

Look at 42.5m trimaran superyacht Adastra by McConaghy Boats and you see the future – not only of yacht design but also of the industry itself. Her performance and development have global aspects: she has a range of 10,000 nautical miles and was designed in Britain for expatriate owners, who live in Hong Kong, to cruise Indonesia and the world. The interior was designed by a Dane who happens to be the first female commodore of the Royal Hong Kong Yacht Club, and the entire vessel was built in China at a yard owned and managed by Australians. Yet Adastra is not extreme for extreme’s sake.

Her owner, Anto Marden, spent many years in the shipping business and has sailed all over Southeast Asia in his 13.7 metre trimaran Mazinga, designed by John Shuttleworth . He has extensive knowledge of these boats and the stability of their form, and has known Shuttleworth for some 30 years.

About eight years ago, Marden began thinking of a larger yacht with global range. For such a journey he wanted something faster than a sailing boat, and sought an oceangoing powerboat capable of a steady 16 to 18 knots in the open sea and a range of 4,000 nautical miles at 17 knots.

‘The owner had four key requirements for the design of his large power trimaran,’ Shuttleworth says, ‘offshore seaworthiness, comfort, economy of operation and shallow draught.’ The interior was to complement the modern exterior shape and reflect the family’s Asian home. Primarily, it would cruise with just the Mardens aboard plus crew, but two additional cabins were planned to accommodate occasional guests. ‘He clearly wanted a sexy boat with wow factor.’

Focusing on economical range, it would have to be as light and easily driven as possible. Both aerodynamics and hydrodynamics had to be considered, and the exterior would have to be smooth to reduce friction from water passing over the structure. As Shuttleworth, now assisted by his two sons, Orion and Sky, developed ideas, they became convinced that to meet the brief, the vessel’s skin also would have to form part of the torsional strength – a sort of monocoque approach. In the 1980s, Shuttleworth had come up with the concept of what he calls ‘integrated structure.’ This results in boats that are lighter, stiffer, stronger and less likely to twist than previous multihull designs, an arena in which Shuttleworth excels.

Unlike round-the-world speed-record boats with collapsible pipe berths, Adastra would require good load-carrying capacity to provide for luxurious accommodations. Whereas most trimaran outriggers skim the water, her outriggers were expected to be continually immersed as she cut through the waves. Although this increases drag over the skimming type by about eight per cent, it greatly decreases rolling and increases stability. The crossbeam needed to be higher above the water to reduce any impact and noise caused by slamming.

To make the structure as light as possible, the vessel would have to be built in composites, as would much of the interior, but this allowed the design of the flowing shapes that define the futuristic appearance. And to achieve very low fuel consumption, every element was scrutinised. If there was a lighter way to achieve the required function, it was sourced or built from scratch.

This kind of effort required a builder who would collaborate, and Marden and Shuttleworth turned to Mark Evans, co-owner of the Australian shipyard McConaghy Boats. McConaghy, which has been in business for 45 years, has an outstanding reputation for building performance sailing boats, including renowned maxis such as Wild Oats X and Wild Oats XI , Moneypenny and all three Alfa Romeos . The yard also has turned out Whitbread and Volvo Ocean Race racers and has great expertise in carbon fibre.

The yacht’s deck and superstructure are constructed of carbon fibre with a carbon/Nomex honeycomb core, while the hull is an e-glass/Kevlar foam sandwich. Core thickness varies from 20 to 40 millimetres. All the structures were resin infused to ensure high quality and reduce weight. The interior is oak veneer over honeycomb. The most dramatic weight savings, according to Evans, came from changing the makeup of the upper structure from foam/e-glass to carbon/Nomex. ‘It halved the weight of the core and I would guess saved us 200 to 300 kilos,’ he says. The result of all this effort, says Shuttleworth, is that Adastra displaced operates with light ship displacement of 52 tonnes.

‘Throughout the design process, we gave careful consideration to ergonomics and how the boat would be used by the owner and her crew,’ says Orion Shuttleworth. ‘What was particularly challenging was this design was the first of her kind. We had to anticipate problems and find practical solutions.’ This creative approach was recognised at the 2013 World Superyacht Awards, where Adastra won the Most Innovative Yacht prize, and at the ShowBoats Design Awards with an award for naval architecture and a judges’ commendation for exterior styling.

‘The fantastically low weight, along with her easily driven exterior, has resulted in one of the, if not the, most fuel-efficient superyachts ever,’ says Shuttleworth. At light load, the yacht burns 4.5 gallons of fuel an hour to cruise at 10.5 knots, which gives a range of 10,000 nautical miles. At 17 knots she uses 98 litres an hour and has a range of 4,000 nautical miles. Her top speed, delivered by one 1,150hp Caterpillar C18 engine, is 23.2 knots.

‘Although the owner did not require the vessel to be classed, we chose to use the LY2 Code as a guide for safety and fittings. In cases where this was not practical, we developed creative solutions to provide safe alternatives,’ says Orion Shuttleworth.

The large wraparound saloon windows were a structural challenge but they helped the designers lengthen the exterior lines. They also create fantastic views and an atrium effect inside.

Integral to the yacht’s development was adding Danish-born Inge Strompf-Jepsen to the team. Operating an architectural design company in Hong Kong, she mixes Scandinavian style with Asian influences. The idea of exposing the curved carbon-fibre beams running through the deckhead of the saloon to save weight was seen as a positive by Strompf-Jepsen, who thinks the exposed structure gives the feeling of being inside the ribcage of a whale.

The spacious saloon of Adastra is almost circular in shape and offers superb views to those in the lounging and dining areas. A door through the windscreen allows access to a large foredeck sunbed that can be shaded with an awning suspended from carbon-fibre poles set into the deck. The main helm station, which has two seats on a plinth that give a view over the cabin top, is in a raised pilothouse between the saloon and the aft deck. Hatches in the overhead provide ventilation but also allow the helmsman to put his head out for a 360-degree view when docking.

To minimise the helm station’s intrusion on the saloon, it is housed in a wineglass-shaped structure that forms an interesting architectural feature. Behind this is the shaded cockpit, which has an undulating sofa to port and, to starboard, a dining table tucked within the structure of the main hull, the supports for the pilothouse and the rigid bimini top. This covered aft deck on Adastra can be enclosed with a set of sliding side covers.

The open deck running aft provides stowage for a 4.8 metre tender that is launched with a removable carbon-fibre davit. A second three metre tender is stowed alongside a freezer in the garage below the aft deck, which has a door that hinges out to create a bathing platform.

Accommodation on this superyacht is for nine guests and six crew. The master cabin, with access from the deck saloon, is aft in a section of the main hull that flares above the waterline, while the guest cabins are forward of the engine room. Further forward are the crew cabins and galley.

Interior materials are limited to light honey oak and semi-gloss white paint with occasional brushed stainless-steel trim. The soft contrast of the surfaces is augmented by white woven fabrics and blue-and-white ikat fabrics collected by Elaine Marden in Indonesia.

The sponsons can be reached via steps sculpted into the support wings. They look like louvers on a sports car, and from some angles they almost disappear from view. Removable rails fit into the aft edge of the wings and there are fixed handholds. Liferafts slot into quick-release bins on the back edge of the wings.

‘ Adastra takes the power trimaran concept further than has ever been attempted before,’ Shuttleworth says. ‘The challenge of turning this concept into a viable luxury yacht that meets the needs of a very experienced ocean-voyaging couple and their family has led us to develop new thinking on stability, very low fuel consumption and comfort at sea for this type of craft.’
