French studio VPLP introduced a 47-meter concept catamaran Evidence powered by a 400-square-meter wing-sail that produces twice the power of a conventional sail.

Leveraging on their extensive experience in the field of rigid sail development for America's Cup racing boats, French naval architects designed an «eco-friendly» yacht concept, featuring an automated wing-sail integrated into a hybrid propulsion system.

«Evidence offers the stability, space, and performance of a catamaran with the bonus of a simple yet pioneering rig – so that you and your crew can enjoy the peace and pleasure of sailing under wind power,» explains VPLP partner, Marc Van Peteghem. 

Reefable, furlable and fully automated wing-sail is purpose designed for superyachts, as it can be easily handled on boats that otherwise would require a twice as larger sail plan to achieve the same level of performance.

The 47.7-meter Evidence has a beam of 16.6 meters, a 3-meter draft, and a 400-square-meter wing area. It is able to accommodate 12 guests and 10 members of the crew. Her designers claim that she is meant for crossing the Atlantic.    

The wing-sail is a modification of the recently launched automated sailing system Oceanwings originally developed by VPLP for cargo ships and fishing vessels.
