What Computed Wing Sail does
Computed Wing Sail (CWS) is a French engineering company developing wind-assisted propulsion hardware for commercial shipping. Its single flagship product, the Airfin350, is a rigid, asymmetrical-profile wing sail with a patented folding mechanism that enables efficient tacking and reduced airdraft, supplemented by an automated wind tuning system that self-adjusts to conditions. The company claims the Airfin350 delivers roughly twice the performance of symmetrical wing sails of the same size and supports operation down to 20° apparent wind angles, with stated fuel savings of 30-50% on equipped vessels.
CWS targets commercial vessel operators across LNG tankers, container ships, and Ro-Ro/Ro-pax segments, addressing both retrofit and new-build installation paths. Its primary value proposition is alignment with binding maritime decarbonization frameworks — IMO EEDI, EEXI, and CII, plus the EU ETS and Fuel EU Maritime regulations — positioning the wing sail as a compliance tool as much as a fuel-efficiency upgrade. Supporting engineering services include 3D wind tunnel testing, ship balance and EEDI reduction analysis, and operational fuel economy optimization delivered through a routing software partnership with Adrena, with independent validation from MARIN, D-Ice, and Blue WASP.
The business model is direct B2B enterprise sales: quote-based custom hardware pricing per vessel, paired with preliminary engineering studies sold as professional services. The company has no disclosed revenue, no named commercial customers, and no public pricing; it is currently taking orders for 2026 deliveries from its first factory in Saint-Nazaire, opened in 2024. The company is privately held, founder-led under CEO Laurent Schneider-Maunoury, headquartered in Saint-Nazaire with a Paris office, and has raised approximately $6.97M in cumulative disclosed funding, including a $6.89M round in November 2025 led by Bpifrance and Supernova Invest.
