Windcoop

Windcoop is a French maritime transport cooperative (SCIC) that operates wind-powered container ships. Its stated mission is to accelerate the transition of maritime transport toward a low-carbon model, using sails and wind energy as the main propulsion source. The company presents itself as a militant shipping line, combining environmental goals with a cooperative ownership structure that invites individuals, companies and public authorities to become members (sociétaires) and co-owners of the project. Windcoop's first vessel, the Miaraka, entered construction in 2025 and is scheduled to link Marseille, France, to Madagascar in the summer of 2027. The ship is designed to maximize wind use, with three rigid wings totaling 1,050 m² of surface area. It is intended to carry 210 twenty-foot containers and to achieve up to 60% wind propulsion at 8 knots, with energy savings between 44% and 57% on the Marseille–Madagascar line. The initial route was planned through the Suez Canal, but due to the geopolitical context in the Red Sea, the Miaraka will use the Cape of Good Hope route until conditions allow a return to the original itinerary. Via the Cape of Good Hope, the transit time is 42 days at an average speed of 9 knots, with 52% sail propulsion and a 44% reduction in CO₂ emissions; via the Suez Canal, the transit time is 30 days at an average speed of 8 knots. As a cooperative, Windcoop is owned by its members rather than by traditional shareholders. The company is headquartered in France and its operations are focused on the Marseille–Madagascar corridor, with ambitions to develop a new model of shipping company that is low-carbon and attentive to people and the environment. The brand is associated with the French maritime transport sector and with the broader movement for sustainable, wind-assisted shipping.

Windcoop is a French maritime transport cooperative (SCIC) that emerged around the goal of decarbonizing shipping through wind propulsion. The organization is structured as a cooperative, allowing individuals, companies and public authorities to become members and co-owners. Its first major project is the Miaraka, a wind-powered container ship that entered construction in 2025. The vessel is designed to operate on a route between Marseille, France, and Madagascar, with the line scheduled to open in the summer of 2027.
