Super Bowl Update

From Design to Reality, The Adastra Trimaran:


The luxury streamlined 42-metre trimaran Adastra caught the attention of the world’s press when it was unveiled in China by John Shuttleworth Yacht Designs Ltd. At that time, computer renderings (like the ones below) of the sleek and futuristic looking trimaran made the rounds on the internet.









Now, after 4 years in build by McConaghy boats in Zhuhai China, the fuel efficient 42.5 m Trimaran Adastra has been launched into the Pearl River.



No longer just drool-worthy cgi images, but here are actual photos of the boat as it was taken out for it's first launch:





and afloat:




It took five years for Adastra to be delivered to Hong Kong couple Anto and Elaine Marden, who commissioned a superyacht that could meet their desire for ocean voyaging with the level of comfort and style that would be expected in a yacht of this class and size.

Adastra Interior (renderings designed by Jepsen Designs of China):










“No effort has been spared in the challenge to produce a beautiful yacht that will have low fuel consumption and yet provide excellent sea keeping qualities and luxurious accommodation,” said Orion Shuttleworth, who collaborated on the exterior designs with John Shuttleworth.







The Superstructure is carbon fibre with Nomex honeycomb core, the hull is Glass/Kevlar foam sandwich and the interior is light weight 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.

Weighing in at 52 tons, the vessel has a maximum speed of 22.5 knots and a range of 4000 nautical miles. She can also be controlled from an iPad within a 50-metre range.

Here's a video of how the yacht can be controlled with an ipad using the iiCaptain app:


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 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 Aft Deck:






The garage door has been designed to fold out and create a large dive platform. 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.

Overhead of the Helm Station:


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