Hardware

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.
Software

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.

Eco-routing
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.
