Adastra is a 139 foot (42.5m) power trimaran designed by John Shuttleworth. She is being built in China at McConaghy Boats, for Hong Kong clients Anto and Elaine Marden, already owners of Mazinga, a sailing trimaran from the same designer.
Adastra’s futuristic look gets her called “alien attack vessel” by some bloggers. The hull is made of glass and Kevlar foam while carbon fiber is used for the rest of the yacht, making it lightweight. The interior is light weight oak using honeycomb panels, and is designed by Jepsen Designs in Hong Kong.
The luxury trimaran has low fuel consumption thanks to a fully automated fuel management system. The outrigger height has been optimized for ease motion at sea and a new outrigger shape has been developed to increase stability in waves. Powered by a main Caterpillar engine and two outrigger Yanmar engines, her max speed is 22.5 knots and she can cover 4000 miles when cruising at 17 knots.
Her 16m beam allows a spacious salon area on the main deck with a panoramic view on the waterscape. Forward facing door through the window gives an easy access to s large sunbed on the foredeck.A lounge area and dining area is located on the aft deck, as well as a space for a 4.9m tender and below is a garage for another 3.1m tender. The garage door folds out to create a large diving platform.
