We’ve been holding this one for a while…
Eastern Pacific Shipping has completed its second eSAIL® installation, now on the newbuild MR tanker EPS Pacific Sunstone in China.
🗣️ Mirtcho Spassov, Decarbonisation Manager of EPS: "Our experience with Pacific Sentinel demonstrated the operational performance and practicality of the eSAIL® system, making the integration of the technology from the outset on Pacific Sunstone a natural step.”
Not all weekends look the same, and ours came with cranes and sails 🏗️⛵
We’ve completed the first eSAIL® installation under our agreement with Maersk Tankers.
➡️Four 24-m eSAIL® units installed
➡️First of 20 across five MR tankers
➡️Two-step installation
Huge thanks to @MaerskTankers, Njord, Yiu Lian Shipyard and EDR Shipyard, and to the entire bound4blue team.
First installation done and four more to go!

One of those milestones you don’t forget… 🚀
We’ve closed a US$44M funding round backed by leading shipping & climate investors. A strong signal that wind propulsion has shifted from “future tech” to one of the most scalable and immediate decarbonisation solutions in shipping.
With independently verified savings of up to 40%, growing demand, and expanding production in Europe & Asia, our suction sails are taking centre stage.
2025 isn’t over yet… more milestones coming.💥
