French cargo ship combines rigid sails, hybrid engine, and digital navigation to reduce emissions in the Atlantic while transporting containers, vehicles, and industrial cargo between ports in Europe and North America on a regular commercial route.
A French cargo ship of 136 meters has begun operating a regular transatlantic route with rigid sails, a hybrid engine, and digital navigation systems, in an initiative aimed at reducing the use of fossil fuels in commercial maritime transport.
Developed by Neoline, the Neoliner Origin was designed to transport containers, wheeled cargo, and out-of-gauge volumes between ports in France, the United States, Canada, and Saint-Pierre and Miquelon.
The vessel’s proposal is to use wind as the main energy source whenever navigation conditions allow, without eliminating the technical resources used by modern cargo ships on long-distance commercial routes.

To maintain operational predictability, the ship features hybrid sail/motor propulsion, a system used in maneuvers, periods of low wind, and situations where meeting port windows requires additional navigation control.
Sailing cargo ship uses carbon masts and automated system
Classified as a ConRo ship, the Neoliner Origin combines capacity for containers and ro-ro operation, a format in which vehicles, machines, and rolling cargo enter and exit the vessel through specific ramps.
The vessel was designed to transport 265 TEUs, in addition to rolling equipment and large dimension cargo, in a configuration aimed at industrial, logistical demands, and operations that require the movement of various volumes.
In the propulsion system, the central component is the rigid sails installed on the ship’s structure, integrated with carbon masts and automated adjustment mechanisms during navigation.
According to CMA CGM, the cargo ship uses 3,000 square meters of rigid sails, distributed across two carbon masts over 70 meters high, designed and built by Chantiers de l’Atlantique.
During the crossing, the orientation of the sails is automatically adjusted to improve wind capture, according to weather conditions and the parameters defined by the vessel’s navigation systems.
Unlike traditional fabric sails, the SolidSail technology was developed for large vessels, with foldable masts and automated control integrated with stability, route, and cargo operation systems.
Transatlantic route connects ports in Europe and North America
The line operated by Neoliner Origin connects Saint-Nazaire and Montoir, in France, to Baltimore, in the United States, Halifax, in Canada, and Saint-Pierre and Miquelon, a French territory in the North Atlantic.
According to Neoline, the service operates as a monthly route intended for the transport of ro-ro cargo, containers, and out-of-gauge volumes, with regular operation throughout the year.
Operation in the North Atlantic involves relevant industrial markets and requires continuous logistical planning, as the route links ports used by shippers who depend on deadlines, coordinated schedules, and delivery predictability.
On routes of this type, commercial ships need to meet port windows, coordinate berthings, and maintain regularity for supply chains connected to factories, distribution centers, and international operators.
CMA CGM began offering the Neoliner Origin directly to its customers in 2026, as part of a commercial partnership established with Neoline for the operation of the transatlantic route.
According to the company, the solution expands its low-carbon transport offering between France and North America, with scheduled departures from Baltimore and Montoir.
Emission reduction depends on wind and navigation
The environmental estimate is one of the points presented by the companies involved in the project, especially due to the combination of wind use, hybrid engine support, and digital planning of crossings.
CMA CGM states that the Neoliner Origin can reduce greenhouse gas emissions by up to 80% to 90% during ocean crossings, compared to conventional diesel-powered cargo ships on equivalent operations.
This percentage can vary according to the trip profile, weather conditions, the chosen route, and the effective use of sails along each stretch of the crossing.
For this reason, the ship combines wind propulsion, support engine, and real-time meteorological routing digital tools, used to define more efficient trajectories without compromising service regularity.
In relation to projects based exclusively on alternative fuels, the Neoliner Origin uses wind as a direct source of mechanical energy, reducing the dependency on specific refueling during navigation in open sea.
The application of this technology on a commercial scale, however, requires an adequate hull, resistant masts, automated control systems, and route planning compatible with the natural variation of winds.
Naval technology harnesses wind on an industrial scale
The resumption of the use of sails in ocean transport occurs in a different format from historical navigation, with integration into composite materials, digital systems, and auxiliary propulsion.
The Neoliner Origin combines carbon masts, automated control, weather simulations, and hybrid propulsion in an architecture designed to operate in contemporary logistics chains.
The project began development for Neoline in 2016 and was conceived as a ro-ro cargo ship intended for transoceanic crossings with commercial cargo.
Mauric, responsible for the naval design, states that the model was designed to transport vehicles, out-of-gauge cargo, and general cargo, with commercial speed under sails combined with weather routing.
For shippers, the possibility of reducing emissions without abandoning familiar transport formats is among the commercial factors associated with the use of this type of vessel.
Automobiles, industrial equipment, containers, and special cargo continue to be moved in protected areas adapted to the logistical standard, while the main energy source comes from the wind whenever possible.
Expansion of rigid sails still requires new projects
The technology of rigid sails cannot be simply installed on any cargo ship already in operation, because it depends on structural and operational characteristics planned from the ship’s conception.
Such vessels require specific design, adequate stability, free area for masts, compatibility with ports, and planning to operate on routes where the wind offers significant energy gain.
Due to these requirements, adoption tends to occur mainly in new naval projects or heavily adapted vessels, rather than through quick conversions of entire fleets.
The Neoliner Origin represents a commercial application of this technology on a regular route, but its expansion will depend on costs, operational performance, customer acceptance, and integration with port infrastructure.
As maritime transport moves an essential part of international trade, reductions in fuel consumption on long routes may interest shipowners, logistics operators, and companies that measure emissions in their supply chains.
In this context, the rigid sail appears as an energy efficiency alternative combined with other paths adopted by the sector, such as new fuels, hull redesign, digitization, and operational improvements.
With the entry of the cargo ship into regular service in the Atlantic, France now has a commercial example of the use of rigid sails on a large vessel aimed at international cargo transport.
The evaluation of the project will depend on the ability to maintain route, schedule, operational cost, and effective reduction of emissions over continuous voyages, under real maritime operating conditions.
