Superyacht Adastra a 42.5m Power Trimaran

Described by Boat International as “one of the world’s most amazing super yachts, that could spell the future for efficient long range cruising”, the striking 42.5m Trimaran Adastra is currently under construction at McConaghy Boats in China.

This one-off trimaran designed by John Shuttleworth is being built for Hong Kong clients Anto and Elaine Marden with interstellar voyages in mind.

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 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.

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.

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.
