Hi, we’re bound4blue

The idea for bound4blue was born in 2015 when its founders – José Miguel, Cristina and David – imagined a ship solely propelled by sails to produce energy in a scalable, affordable and renewable manner. While developing the most cost-efficient wind propulsion system they realised that this modern sail could also be applied to co-propel cargo and passenger ships to reduce their fuel costs and emissions, pivotal moment in which bound4blue shifted its focus.

After several iterations working with the market to build a wind propulsion system that met their needs, we came up with the eSAIL.

Valderaduey Inversiones (co-investing with the European Investment Fund), a group of professionals from the maritime industry, and a Barcelona-based Family Office, amongst others supported us financially during this phase.

The eSAIL aerodynamic performance was validated both with CFD modelling and several wind tunnel testing campaigns.

Together with manufacturing companies from the wind turbine industry, we manufactured the first 12-metre-high full scale unit. This unit has been used to perform ground tests and improve the aerodynamic efficiency of the system.

A twin model of the 12-metre-high eSAIL was installed on the longliner Balueiro II in Panamá, being the first fishing vessel in the world to sail with this type of technology.

After that, investment partners Aciturri Aeronáutica, CDTI-Innvierte, a Valencia-based Family Office, Ocean Born Foundation and Climate KIC, amongst others, joined in a following funding round to support us on the commercialisation of our technology.

A 17-metre-high eSAIL was installed on the general cargo vessel La Naumon in Spain, being the largest suction sail in the world deployed on a ship. We also installed the first generation of the tilting system.

The 91 meters length general cargo vessel, owned and operated by the Dutch shipowner, will be retrofitted with two 17-metre-high eSAILs® during a port call.

We will deploy three eSAILs® of 22-metre-high on a RoRo ship, owned and operated by the French shipowner. This will be the first installation of fixed suction sails on a Ro-Ro ship.

We will install four 26-metre-high eSAILs®, expected to be the largest suction sails ever built and installed on a ship. This will also be the first Panamax bulk carrier using suction sails

We have announced a partnership to jointly expand access to the eSAIL technology in Greece and Cyprus with Oceanking, a trusted provider of marine technology solutions

We welcome Dr. Elias Boletis – former Director Propellers and Transmission at Wärtsilä Propulsion- as an external advisor. Elias brings extensive experience and deep industry knowledge to bound4blue as it continues to drive growth and innovation.

We have formed a strategic partnership to promote and sell our technology. Marubeni will promote retail activities for eSAILs both domestically and internationally. It will also act as our exclusive business partner in the Japanese market

We have successfully installed two 17-metre-high eSAILs® on the general cargo vessel Eems Traveller, owned by Amasus. We continue to hold the record as the largest suction sail ever built and installed on a ship

We will install the innovative eSAIL® system on a chemical tanker, making it the first tanker vessel in the world to harness this groundbreaking technology

The Series A funding totals €22.4M, including €6.5M from grants. With the fundraising, we are confirming our leadership in a market now experiencing a sustained growth

Airbus will equip one of the vessels it uses to transport aircraft subassemblies, chartered from shipowner Louis Dreyfus Armateurs, with three 22-metre-high eSAILs®

bound4blue and Louis Dreyfus Company (LDC) announced today a commercial agreement for the manufacture and installation of four 26-meter-high eSAILs® on its chartered juice vessel, MV Atlantic Orchard, in 2024.
