Inside the Insane, Rule-Breaking Trimaran Yacht That Just Hit the Market for $12 Million

For more than seven years it has spun heads from St. Barts to Bali. Now, the rule-breaking 140-foot power trimaran Adastra is up for sale, and could be yours for a cool $12 million.

This futuristic, ocean-crossing projectile was built back in 2012—at a cost of well over $20 million—for Hong Kong–based shipping magnate Antony Marden to cruise Indonesia and Southeast Asia.

But in those seven years, the custom-built, wave-piercing-hulled superyacht has crossed the Atlantic half a dozen times and taken Marden and his wife island-hopping around the globe.

“She’s been the most remarkable boat. Her seaworthiness is quite amazing. We’ve weathered 50-knot winds crossing both the Pacific and Atlantic oceans. She just takes everything in her stride,” Marden tells us.

“She’s also extremely economical. Cruising at 10 knots, we burn just 4.5 gallons an hour. That gives us a range of around 10,000 nautical miles. We recently did St. Maarten to Vigo in Spain and had enough fuel left to head back to the Caribbean.”

Designed by Britain’s Shuttleworth Design and built in China by McConaghy Boats , Adastra was created with a single-minded focus on strength and weight reduction. The hulls are made of a super-strong e-glass/Kevlar foam sandwich, with the deck and superstructure constructed from carbon fiber with a lightweight Nomex honeycomb core. Before fuel and water, it tips the scales at just 52 tonnes.

And it’s quick. Powered by a single 1,150 hp Caterpillar C18 straight-six turbo diesel, Adastra has a top speed of 23 knots with a cruising speed—in pretty much any weather—of 17. For backup, it also has a pair of 110 hp Yanmar diesel engines.

Below decks, Hong Kong–based interior designers Jepsen Design squeezed in accommodations for nine guests and six crew in Adastra ‘s slender main hull.

The full-width owner’s suite in the aft section makes use of the hull’s outward flare from the waterline to add to the feeling of space.

As you can see, the roomy main saloon is big on curves; from the curved ceiling to the curvy built-in furniture, to the large curved windows that flood the cabin with light.

The main helm station sits in the raised pilothouse between the saloon and the aft deck.

What kind of reaction does the Jetsons-style trimaran get in port? “She’s a total head-turner,” says Marden. “She’s pretty much the only boat anyone looks at. Everyone stops and takes a photo.”

So why is he selling? Marden tells us he’s done all the global cruising he wants to and feels it’s time to let a new owner enjoy this very special yacht.

“After seven years, we’ve pretty much cruised to all the places we want to cruise. Now she’s just not getting enough use. We have another yacht at home, so it’s time to sell.”

Right now Adastra is moored in Nassau in the Bahamas , and later this month will head to Fort Lauderdale ‘s Seahaven Marina for a showing to prospective buyers on July 25 and 26. If you’re in the market for a one-of-a-kind trimaran, click here .

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 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.
