adastra yacht 1

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 from 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.


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.


Her 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, economy of operation, and a shallow draft.

ADASTRA’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. 


ADASTRA 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.
