The solution to decarbonized ocean freight

” Be part of a unique and sustainable adventure “

Fleet of 4 vessels planned for 2026/2027

Tonnes of CO2 emissions avoided*
  • The rig is designed so that the engine is never used outside the port. By design, our ships are the only ones to date to keep sailing, eeven in hurricane-force winds.
  • Our ships are designed as passive vessels. We are decarbonising not only the propulsion part of the ship, but also the energy requirements for life on board.
  • Design and procedures conceived, optimised and tested on the basis of 3 years’ feedback on board the Grain de Sail I demonstrator.
  • Core crew and support functions already in operation.

*Internal calculations based on standards estbalished by ADEME (French Governmental Agency for Ecological Transition)


With observed decarbonization rates of over 90%, our operational solution fully meets cargo-owners’ expectations today.

Our Cargo Sailboats

Transport less, transport better: a fleet of cargo sailboats for the cleanest transportation method in the world.
