superyacht adastra

The beautiful superyacht has an exceptionally low fuel consumption and yet boasts excellent sea keeping qualities and luxurious accommodation.

Adastra’s 16 metre beam creates a spacious saloon area on the main deck which offers superb views through a panoramic window and accommodates a lounge area, dining table, and navigation station. A forward-facing door through the saloon window gives easy access to a large sunbed on the foredeck.

The main helm station, which has seating for two, is positioned in a raised pilot house situated between the aft deck and the saloon area and forms part of the cross beam structure.

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 swim platform.

Below deck, extra space was created 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.

Adastra offers comfortable accommodation for nine guests in total and up to six crew members.

The vessel has a fully automated fuel management system which includes an Alfa Laval system for cleaning the fuel.

The anchoring system is unique, with three anchors all driven by carbon fibre drum winches run by hydraulics. The primary anchor is a custom 130kg Bruce style anchor that deploys out of the starboard wing. The bow anchor is 80kg and deploys out of the bow with a carbon fibre arm. The third anchor is 60kg which deploys out of the port wing and will be used as a stern anchor.

The yacht’s superstructure is constructed from carbon fibre with Nomex honeycomb core, the hull is Glass/Kevlar foam sandwich and the interior features lightweight oak cabinetry using honeycomb panels. To help reduce weight, virtually every aspect of the boat is custom built. This includes carbon fibre hatches, portlights, ladders and even hinges, which are all built specifically for the vessel.

Adastra takes the power trimaran concept further than has ever been attempted before. The challenge of turning this concept into a viable luxury yacht led us to further research on stability and comfort at sea for this type of craft. Extensive tank testing and radio controlled model tests in waves were carried out to analyze stability and performance. Outrigger height was optimized for ease of motion at sea, and a new outrigger shape was developed to increase stability in waves. We undertook a state-of-the-art structural analysis of all the major components in the yacht in order to achieve the light weight required for very low fuel consumption.

Today, Adastra remains one of the most iconic superyachts on the water.

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

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.

The open plan gives the sense of being outdoors, especially with the skylights.  Courtesy Burgess Yachts

Adastra is currently listed through Burgess Yachts for $10 million. Here are more images.

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.

The luxury trimaran yacht received 2013 World Superyacht Award for most innovative design and was listed for sale in 2019.

Power trimaran concept and superstructure materials of Adastra

The superyacht is based on a power trimaran concept. The designers incorporated luxury into the trimaran design to make it suitable for ocean voyaging.

Structural analysis was undertaken for all the components of the ship. A computer model of Adastra was tested for wave impact, side slamming and impact of the outrigger riding through waves.

The superstructure of the luxury yacht is made of carbon fibre with a Nomex honeycomb core. The hull is of resin infused epoxy with E-glass and Kevlar skins. The interior is composed of carbon and E-glass honeycomb panels and oak veneered cabinets.

The beam of the ship is 16m and the hull draft is 1.12m. It weighs 52t and has a range of 4,000nm.

The naval architect of the superyacht was John Shuttleworth Yacht Designs. Exterior styling was done by John Shuttleworth Yacht Designs and Orion Shuttleworth Design, while the structural design was by John Shuttleworth Yacht Designs and Applied Structural Analysis. Adastra’s interiors were designed by Jepsen Designs, of Hong Kong.

Construction of the lightweight superyacht by McConaghy Boats

McConaghy has built the components of Adastra to custom design to reduce its weight. The in-house built components include fibre hatches, portlights, ladders and hinges, all made of carbon.

More than 350 craftsmen, designers and engineers of McConaghy in both China and Australia worked on the construction of the yacht. The outrigger of the superyacht was specially designed by optimising its height, allowing easier movement on the waves.

Performance of the unique fuel-efficient Adastra yacht

Adastra was designed to be lightweight for low fuel consumption. The superyacht has a maximum speed of 22.5k and its range at 17k is 4,000 miles.

A SiMON 2 integrated ship surveillance system monitors fuel, security, pump sensors, electrical and lighting systems of the ship.

With a freshwater capacity of 2,700l, Adastra has two 800gph freshwater makers. The vessel’s displacement (light) is 49t while at maximum cruising (with 15,000l fuel) it is 64.8t. The yacht consumes 90l an hour at a speed of 13k and 120l each hour at 17k.

Accommodation and luxury features of Anto Marden’s superyacht

Adastra can accommodate nine guests and up to six crew. The accommodation is provided on the below deck, which is partitioned into two sections. The master cabin is located aft.

Two guest cabins, crew accommodation and the galley are located near the engine compartment. The central hull has been flared above the waterline to create some additional space on the below deck.

The main deck houses a saloon which encompassed a lounge area, dining table and navigation station. It provides views of the ocean through a window. The saloon is directly accessible from the master cabin.

The sunbed is on the foredeck while the aft deck has a sofa and bar area and a dining area. There is a raised platform between the saloon and the aft. The pilot house, accommodating the main helm station, is situated on this platform. The station has seating for two.

Tenders on board Adastra

Adastra can accommodate two tenders. A 4.9m space is made available on the aft deck for a tender. A garage below the deck can shelter a 3.1m tender. The fold-out design of the garage door provides diving space.

Engines fitted and anchor system of the Adastra trimaran superyacht

Adastra has a single Caterpillar C18-1150hp engine at 2,300rpm and two Yanmar 110hp outrigger engines rated at 3,200rpm. Two 36kW generators are linked to the outrigger engines and one 26kW generator is installed in the main engine room.

The anchoring system of Adastra comprises three anchors. The 130kg Bruce style primary anchor is deployed out of the starboard wing. The 80kg second anchor is deployed out of the bow with an arm. The third is a stern anchor and weighs 60kg. It is deployed out of the port wing.

The anchors are driven on hydraulics-run winches. The carbon-fibre winches and anchor arms were custom-built. The arms fold inside the yacht, thus remaining invisible.

The vessel features an Alfa Laval fuel cleaning system for cleaning the engine.

On winning the 2013 Showboats award for naval architecture, Boat International stated. "this yacht will have the best performance in the most sea states of all those presented" . To find out more about the award winning naval architecture used in these designs read the article "Adastra - The search for a seakindly fuel efficient vessel". Read more.

Her slender hulls and streamlined exterior allow her to travel faster in the open ocean and at 17 knots she has a 4,000nm range so can comfortably cross both the Atlantic and Pacific oceans at hi-speed. Measurements taken during the sea trials show that her fuel consumption at 10.5 knots is as low as 17 litres per hour when carrying 10% fuel and water. At cruising load (20 tonnes fuel and water) she uses just 25 litres per hour therefore on delivery trips her range is 10,000nm starting with 30,000 litres of fuel.

Adastra takes the power trimaran concept further than has ever been attempted before, previous vessels like Earthrace and Cable and Wireless were stripped out record breaking machines. The challenge of turning this concept into a viable luxury yacht has led us to further research and develop new thinking on stability and comfort at sea for this type of craft. Extensive tank testing and radio controlled model tests in waves have been carried out to analyse stability and performance. Outrigger height has been optimised for ease of motion at sea, and a new outrigger shape has been developed to increase stability in waves.

We have undertaken state of the art structural analysis of all the major components in the yacht in order to achieve the light weight required for very low fuel consumption. The deck and superstructure is constructed from carbon fibre with Nomex honeycomb core, the hull is glass/kevlar foam sandwich and the interior is lightweight oak cabinetry using honeycomb panels. To help reduce weight further, virtually every aspect of the boat is custom built. This includes carbon fibre hatches, toilets, portlights and ladders, which are all built specifically for the vessel.

Aerodynamics and hydrodynamics above the water line were carefully considered as we developed the overall exterior shape and we kept the boat streamlined both for air and water passing over the structure. The smooth seamless, unbroken surfaces also help to reduce weight as the outer-skin forms part of the structure to absorb torsional loads.

Exterior Deck

Adastra's 16 metre beam creates a spacious saloon area on the main deck which offers superb views through a panoramic window and accommodates a lounge area, dining table and navigation station.

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. Adastra offers comfortable accommodation for nine guests and up to six crew members.

Wheelhouse Deck

The main helm station, which has seating for two, is positioned in a raised pilot house situated between the aft deck and the saloon area and forms part of the cross beam structure.

The vessel's profile has been kept low to reduce the vertical centre of gravity and improve stabilty in waves. The overall shape has been kept streamlined to optimise aerodynamics and hydrodynamics above the water line and the smooth unbroken surfaces help to reduce weight as the outer-skin forms part of the structure to absorb torsional loads.

$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.

This popular show is dedicated not only to the specialists of the market segment and professional sportsmen but also to those who consider sailing sport to be their hobby and well cherished dream.

The project is the result of joint efforts of the Crocus Expo International Exhibition Centre and the National Marine Industry Association. The event is supported by Aston Martin Moscow, Burevestnik Group logistics department and the Yachting specialized magazine. Moscow Boat Show is the largest project in Russia presenting all the best in the world of yachting.

The exhibition annually shows high level of attendance and has already proved as significant and noteworthy event in the world of yachts and boats. Every year new exhibitors join the list of participants, genuine “sharks” of yachting business, the quantity of visitors considerably increases and the exposition becomes more sated and diverse.

The best companies professionally involved into yachting and small navigation business – 180 exhibitors from 17 regions of the Russian Federation and 15 countries traditionally presented the best and the newest in the world of yachting at 2011 edition: from design and facilitation of vessels and up to cruising and training courses for beginning skippers. In 2011 the overall exhibit space comprised 18 000 sq m. More than 25 000 visitors came to the show.

This year the exposition space will increase up to 30 000 sq m and will be accommodated in 4 exhibition halls. The scale of the project confirms confident positions of its positive development. The organizers will try to arrange a genuine fiesta of water on land!

Quite a number of foreign exhibitors will participate in the show. Foreign companies show increasing interest to yachting business in Russia.

Moscow Boat Show provides the perfect platform from which to preview new products, evaluate market trends, and establish long-lasting and commercially profitable partnerships. Despite the dynamic changes taking place in Russia and the rapid growth of the yachting sector, the show continues to complement and reflect the industry’s demand and is a promotional opportunity not to be missed!

As its popularity and success rate has grown over the last years Moscow Boat Show 2012 has developed to incorporate more than just an exhibition. These special events serve to attract leading exhibitors and visitors and allow all participants the chance to broaden their knowledge and of course their sales potential.

Moscow Boat Show helps representatives of yachting business to get acquainted with their Russian colleagues and gradually improves national yachting market to a new level. It is obvious that for 4 years of its running the project has turned to a status event of the international exhibitions calendar. The organizers of the exhibition aim to bring together on the same platform all key national and worldwide players and to offer an excellent platform to encourage networking among specialists and visitors in order to accelerate the development in this field as well as implementing new technologies, the newest equipment, materials and components.
