French tyre maker Michelin has won approval from DNV for the first inflatable and retractable automated wing sail for ships and signed up to transport its products across the Atlantic with sailing cargo carrier Neoline.

Michelin’s Wisamo wing sail system has been given approval in principle by the classification society, and a 100-square-metre unit will be tested on the 1,690-lane-metre Compagnie Maritime Nantaise ro-ro cargo vessel Pelican (built 1999).
