Dutch wind-assisted propulsion system (WAPS) company Econowind is launching a new 5-series VentoFoil, a larger steel suction wing system for oceangoing vessels. T
The new 30m 5-series model is aimed at deepsea ship operators, and is based on the same principles as the company’s successful 3-series wing.
The 5-series targets owners and operators of larger vessels, looking for practical ways to cut fuel consumption and improve regulatory compliance. The launch is considered a next step for Econowind, after selling more than 150 suction wings across a broad range of vessel types and trades. After gaining traction in shortsea and regional shipping markets, the company is now setting its sights on larger vessels and longer trading patterns, where the fuel-saving potential of WAPS becomes even more compelling.
The first 5-series unit will be installed on a Boomsma Shipping vessel during 2026, giving the new model its commercial debut. The order reflects the Dutch shipowner’s continued confidence in VentoFoils as a practical way to reduce fuel consumption and support more sustainable operations.
Johan Boomsma, Boomsma Shipping, said: “As a returning customer, we are pleased to use VentoFoils again on our vessels, now in the form of the 5-series. Wind propulsion has proven its value both economically and environmentally. With high fuel prices adding to the urgency, this is a logical next step for us. Energy efficiency is high on our agenda, which is why our eight newbuild vessels will be all delivered wind-ready. The first, Frisian Future, will enter service in May.”
To support its move into deepsea shipping, Econowind is organising production in the Far East, close to where a large share of the world’s new vessels are being built. The aim is to bring manufacturing closer to major shipbuilding hubs and make it easier for owners and yards to integrate the larger VentoFoil units into newbuild projects.
Econowind CCO Chiel de Leeuw added: “The 3-series has shown that our technology works in daily operations. With the 5-series, we are bringing that proven concept into the deepsea market.”
Accoding to Econowind, the launch underlines its view that deepsea shipping is the next growth market for WAPS. Econowind’s VentoFoil uses boundary-layer suction technology to generate additional thrust from wind, reducing the power required from the main engine. The company positions the system as a practical and robust solution with limited deck impact, bridge-controlled operation and the ability to tilt the units when required for cargo operations or air-draught limitations.
