The marine propulsion of tomorrow
Powerful, automated, zero-carbon
Using directly the power of wind to assist your ship's engine, our wing-sails generate considerable fuel savings and allow you to face the IMO regulations (EEDI, EEXI,CII) and European reuglations (ETS,Fuel EU).
The perfect shape
Airfin350 is a rigid wingsail designed to decarbonize shipping by delivering outstanding performance with its asymmetrical profile, optimized for all wind directions.
🔑 The secret? Our patented folding system allows the wing to tack efficiently and reduce its airdraft when needed—maximizing both performance and practicality.
A patented inversion system
The wind engine check list
- Power : Optimal lift thanks to a rigid asymmetrical profile
- Regularity : Best in class lift/drag ratio to go upwind via aerodynamic fitness inspired by aeronautics
- Ease of use : Light, low footprint, folding wing (patented), quick installation without dry dock
The optimal trim
Our system is able to tune itself automatically depending on the wind conditions to ensure optimal savings on our ship.
The exceptional lift-to-drag ratio simplifies the integration with existing hulls and propulsion systems, giving twice the performance of a symmetrical wing-sail of the same size.
The maximum power
On a ship sailing 16 knots, even the Atlantic winds are rarely at broad reach.
That's why the performance very close to the wind (20° apparent wind) is so important.

Full performance for your ship
CWS is working with several partners to provide the most accurate performance predictions for our wing. This includes full 3d wind tunnel testing, ship balance analysis, EEDI reduction analysis and operational fuel economy through optimized routing.
We can also work with several third-party modeling companies in order to provide you with an independent validation of our system.

Know your ship and start saving now !
EEDI and EEXI constraints are one of the main preoccupation of shippers. Thanks to our partnership with Adrena and working in collaboration with MARIN, D-Ice and Blue WASP we can provide you with not only a historical assessment of what a CWS installation would provide … But also the savings you can start achieving right now using routing software on your ship.
