The switch to low-carbon fuels, the application of technical and operational optimization methods and the adoption of new technologies to reduce emissions without impacting your economics can feel overwhelming.

What if we told you that there’s a solution that makes your route to sustainability profitable? One that involves going back to the origins of shipping and harness the power of wind.

What wind propulsion

could do for you

Yes, wind propulsion – a simple solution that served humanity for thousands of years – can help you gain:

More Profits

You have the flexibility to speed up or down if the market requires it. In the end, both options have a positive impact on your bottom line. If that wasn’t enough, you can also generate tradable carbon allowances.

More compliance

The use of wind power as an auxiliary source of propulsion reduces the ship’s reliance on fossil fuels, contributing to lowering its emissions and helping you achieve EEXI and CII compliance.

More sustainability

By reducing the amount of fuel burnt you can generate a positive impact on the environment. This, in turn, can improve your market reputation and make you more attractive to customers and financiers.

So many great reasons

to love our eSAIL

Our suction sail – named eSAIL® – combines the advantages of rigid wing sails and rotor sails, avoiding its disadvantages.

Here’s what people
