The system

  • Traction wing

    1000m² of sails to pull the vessel thanks to its dynamic flight
  • Flight control pod

    An autopilot and 3 actuators to guide and control the wing
  • Digital twin

    Modelling of the vessel with Seawing to calculate the trajectory and transmit it to the pod
  • EcoRouting

    Optimising the use of Seawing with maritime and aeronautical data
  • Deck equipment

    Deploy, launch, recover and store the kite
  • 100 tonnes of traction

    Estimation of the traction generated by 1000m² of sails in dynamic flight


Deck equipment

The deck platform allows the automated take-off and landing of the parafoil wing. It consists of a mast, carts, winches and a storage area. The cart system releases the wing from its storage before being inflated at the top of the mast for take-off.

Flight equipment

Each flying sub-assembly (comprising a parafoil wing, a flight control pod and an umbilical cable) controls the automated and optimal flight of the wing. The wing is linked to the pod, which in turn is connected to the ship by the umbilical cable, transmitting traction while transferring data and power between the ship and the pod. During flight, the wing is automatically steered to maximize system power and ensure safety.

Bridge equipment

Our control panel oversees system operations, Seawing flight tracking and routing optimization.


Digital twin

A digital model of the wing and the ship helps calculate different flight scenarios according to the wing's exact position, direction, and wind speed. The physical system is in constant dialogue with the numerical model, with updates every 300 milliseconds to ensure the most efficient use of the system.


Our routing software, developed in partnership with TimeZero by Maxsea (advanced engineering know-how from the ocean racing industry), optimizes the boat's route by capturing the best weather conditions and guaranteeing the ship's arrival time.

Key figures

24 hours Average duration of the installation on a ship.

Airseas' Seawing technology requires minimal space on the foredeck and is bolted on, making it easy to install during a simple dock stop (no dry dock required).

30mn Seawing deployment sequence.

The ship's captain, by a push of a button, activates the deployment of Seawing. The wing is automatically taken out of its storage tank, unfolds at the top of a 35m mast, and takes off to position itself at the zenith to start pulling the ship.

300m Altitude of Seawing above sea level.

Seawing climbs in altitude to seek more robust and stable winds.

150km/h Dynamic flight speed of Seawing.

The parafoil wing produces "figures of 8 loops" to generate ten times more traction than a kite in static flight.
