John Shuttleworth and Superyacht Adastra appear in Mazda's new Advertising Campaign.

In August 2013 Mazda approached John Shuttleworth with the offer of appearing in their Challenger advertising campaign. The Mazda team felt that John's interest in fuel economy and "blank sheet of paper" approach to the design of the Adastra trimaran matched the philosophy of their new SKYACTIV TECHNOLOGY. Discussions with the Mazda production team revealed many similarities in the way both Shuttleworth Design and the Mazda engineers have challenged convention in the drive to create fuel efficient vehicles, whether on land or at sea.

John participated in creating advertisements for TV, cinema, web and print. The Shuttleworth designed Adastra trimaran uses one seventh of the fuel of a conventional superyacht of the same size, and can travel halfway around the world on one tank of fuel. The webisode shows the story of how John came to design the vessel with stunning shots of Adastra underway.

  ".....this project could be compared to Team GB members winning an Olympic gold in front of a home crowd; an experience that will almost surely never be repeated. While there is little doubt the yard will go on to build more superyachts, I predict they'll never build one as significant, iconic and stunning as Adastra. "
