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,...).
Our patented technology allows us to design a thick, assymetrical wing-sail able to change tack to use port and starboard winds.
The exceptional lift-to-drag ratio allows it to use wind power by almost all wind conditions, including on fast ships.
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.
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.

CWS is working with several partners to provide the most accurate performance predictions for our wing. This includes 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.

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.
