Dutch firm targets oceangoing vessels with larger suction wing system
Zeewolde, April 13, 2026 – Econowind is stepping into the deepsea segment with the launch of its new 5-series VentoFoil, a 30 metre suction wing designed for larger oceangoing vessels.
Unveiled in Heeg last week, the system builds on the company’s smaller 3-series units, which have already been deployed across shortsea and regional trades. With more than 150 suction wings sold, the company is now aiming at a segment where fuel savings can scale significantly.
Deepsea shipping presents a different equation. Longer voyages and higher fuel consumption mean even modest efficiency gains can translate into substantial cost reductions. That is where wind-assisted propulsion starts to shift from niche to practical tool.
First installation secured with Boomsma Shipping
The first 5-series unit is scheduled for installation this summer on a vessel operated by Boomsma Shipping, marking the commercial debut of the larger system.
“As a returning customer, we are pleased to use VentoFoils again on our vessels, now in the form of the 5-series,” said Johan Boomsma. “Wind propulsion has proven its value both economically and environmentally.”
Boomsma added that fuel price pressure is accelerating decision making. The company plans to deliver eight newbuild vessels that are wind ready, with the first vessel, Frisian Future, entering service in May.
Production shift supports deepsea ambitions
To support this move, Econowind is organizing production capacity in the Far East, closer to major shipbuilding hubs. The strategy aims to simplify integration into newbuild programs and reduce logistical complexity for shipowners.
“The 3-series has shown that our technology works in daily operations,” said Chiel de Leeuw, Chief Commercial Officer. “With the 5-series, we are bringing that proven concept into the deepsea market.”
The VentoFoil system uses boundary layer suction to enhance airflow and generate additional thrust. The units are bridge controlled and can be tilted to accommodate cargo operations or air draft restrictions, keeping deck impact limited.
As regulatory pressure builds and fuel costs remain volatile, the question for deepsea operators is no longer if wind assistance works, but how quickly it can be scaled across fleets.
