Underway Contracts has once again had the opportunity to work with Clifford Denn, 3D modelling and visualising the BO Concept, developed by Laurent Bourgnon and designed by Clifford Denn for O Yachts.

Far away from the usual definition of a catamaran, they came up with a solution for comfort and performance.

  • Wave piercing wet deck
  • High bridge deck clearance

Clifford Denn Design is primarily involved in luxury yacht exterior styling and interior design, but also cruise ships, product, furniture and graphics. Clifford Denn had first contacted me in late 2010 but it wasn't until early 2012 that we decided to work together. Even though Clifford is situated in France the communication of ideas and designs was free flowing and the time difference turned out to be beneficial for the project. Clifford has done a fantastic design and with Underway Contracts experience in modelling, design and development, it has brought the project one step closer to fruition. We look forward to further collaborations with Clifford Denn Design on projects such as this.
