Last July, we provided readers with specs and renderings of the Adastra superyacht, which was being constructed in China by boat builder John Shuttleworth. While it might have seemed like a fanciful concept at the time, yesterday the completed yacht was launched in China’s Pearl River.

Hong Kong-based shipping industry billionaire Anto Marden first commissioned construction of the Adastra five years ago. The finished product is worth US$15 million, and will likely be used by Marden and his wife Elaine to sail between two islands that they own off the coast of Indonesia.

The trimaran measures 42.5 by 16 meters (139.5 by 52.5 feet), and weighs 52 tons (47 tonnes). It has a top speed of 22.5 knots, although at 17 knots it has a remarkable range of 4,000 nautical miles (7,408 km) – this comes thanks largely to a lightweight hull made from a glass/Kevlar foam sandwich material, a superstructure made from carbon fiber with a honeycomb core, and other weight-saving and streamlining considerations. Its fuel economy is estimated at 90 liters (24 U.S. gallons) per hour at 13 knots, or 120 liters (32 gallons) per hour at 17 knots.

A full-width master cabin located aft with access from the deck saloon, and two further guest cabins - all of which have luxury bathrooms - provide accommodation for up to nine passengers with additional quarters for the craft's six crew members. The yacht is also equipped with a sauna, steam bath and whirlpool ... oh, and one other thing – it can be piloted from a range of 50 meters (164 feet) using an iPad.

I would name mine Eric.

Tis bearing a remarkable resemblance to the "Addy Gil" as sunk by the Japanese whale harpooners.

Mr Stiffy

I prefer sail but still it is real nice.


Leaves me cold, too much boat, to little space.


Is it just me or is 22.5 knots pathetically slow? It's a hair faster than a running athlete!

Samer Helmy

It may appear as "too much boat" but it's just the correct design for a SAFE boat.. waves just pass underneath such a boat without causing roll.. I bet you could have a pool table on a yacht like this..

I don't begrudge thus feller his boat... after all,, if you all had the bux, wouldn't you have done the same?


It looks really slick but if it were any slower it would be a sail boat. Not much cabin space either. Give me a Wally for this money any day of the week.

Matt Fletcher

Not much boat for the money. But, it's not my money.

re; Samer Helmy

For a floating object it is quite fast. Try keeping your world record 100m dash speed for an hour.


For maximum fuel-efficiency they could have integrated the new systems where you lose two knots of speed say from fifteen to 12-13 knots by dropping turbines in the water that are tuned perfectly-and can then travel for 6 hours basically for free at 5-6 knots or have all that electricity for onboard needs. Like adding insulation to your house costs upfront but the payback is long term and awesome. Also if the outriggers were somehow retractable you could then get in places for berths etc. easier-less expensive too!


22.5 knots = 26mph , fastest human 28mph. Average 40' sail cruiser at wind will be about 8mph. Though the 70' MacGregor claims speed of around 13mph to 25mph in strong wind. The MacGregor can be picked up used for about $250,000. Right now there is a the VOLVO ocean race going on with special sailboats that have managed 30mph average over a 24hr period, but it takes strong 40mph+ winds to manage that. So anyway in my opinion it looks cool, but is a big waste o money. Hope a typhoon doesn't wreck it.


Considering the piracy problem that had been at crisis level as late as 3 years ago, particularly around the Straits of Malacca, I'd like to see what this vessel has on board for self defence. Some like it, some don't. Sharp looking craft. Funny that something that sleek could be outrun by a US aircraft carrier.


Neat,I wished I had one.

Look how filthy the water is? A Super yacht should be showen off in real water:)

Paul Perkins

The 42m (140ft) World is not Enough Yacht has a top speed of 70 knots and looks like a normal yacht.


I design and build Multihulls and this one is just a rich man's toy. This same mission if not to show off could be done with a 22m-70' tri or 18m-55' cat at 20% of the cost and far lower fuel use.

Because the water surface area of it is so high it creates a lot of friction drag, thus higher fuel use.

As far as the shape most any of this type has to look at least underwater, about the same. Keeping above water aero is important in eff vessels like this one.


Nice design and engineering - as always when millionaires need expensive toys for their excess money :)

re; jerryd

I question your numbers. I think the the out riggers being thinner but longer would give superior performance but structural strength and weight is important too.


Nice boat, but incredibly slow for design, this boat looks like it should be able to go 140 km/hr.....slow, slow, slow.....guess there are no pirates to worry about in those waters

John Warner

re; John Warner

The boat is designed to give a smooth ride in choppy water and is fairly good on gas.


How many kids could have gone to college if Anto had bought an off-the-shelf boat and offered the rest of the money for scholarships? "It is far easier for a camel to pass through the eye of a needle than for a rich man to attain the kingdom of heaven."
