Superyacht Trimaran Adastra nears completion in Zhuhai

The 42.5m Trimaran Adastra is being built in China for Hong Kong clients Anto and Elaine Marden and is scheduled to launch in November 2011.

"Adastra" is the result of more than 5 years of design and discussion with the owners, to build a yacht that meets the needs of a very experienced ocean voyaging couple and their family, and to provide the level of comfort and style that would be expected in a yacht of this class and size. 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 with interior design handled by Hong Kong firm Japsen Designs.
