We design the marine propulsion of tomorrow

Powerful, automated, zero-carbon

Using directly the power of wind to assist your ship's engine, our wing-sails generate considerable fuel savings and allow you to face the future GHG emissions regulations.

The perfect shape

Our patented technology allows us to design a thick, assymetrical wing-sail able to change tack to use port and starboard winds.

The exceptional lift-to-drag ratio allows it to use wind power by almost all wind conditions, including on fast ships.

The optimal trim

Our system is able to tune itself automatically depending on the wind conditions to ensure optimal savings on our ship.

The exceptional lift-to-drag ratio simplifies the integration with existing hulls and propulsion systems, giving twice the performance of a symmetrical wing-sail of the same size.

The maximum power

On a ship sailing 16 knots, even the Atlantic winds are rarely at broad reach.
That's why the performance very close to the wind (20° apparent wind) is so important.
