WINGSAIL

Industry-leading Upwind Performance

Our Rigid Fixed Wingsail (OW RF) has been specifically designed for Tankers, Gas Tankers, and Ro-Ro vessels with no air draft limitation.

It offers industry-leading upwind performance and thrust-to-weight ratio and delivers double-digit fuel and emission savings. Its modularity, light weight and small footprint facilitate the shipyard integration for both newbuilds and retrofits.

Industry-leading Payback & Easy Integration

Our Rigid Fixed Wingsail (OW RF) has been designed and developed to offer an excellent Payback time. Whether you're retrofitting an existing vessel or working on a newbuild project, the modular, light weight, low center of gravity and small footprint design ensure an easy integration for ship designers and shipyards, with no compromise on the cargo space and stability.

The Rigid Fixed Wingsail (OW RF) is built to be robust, fully electrical and low-maintenance, with an expected lifespan of 25 years.

High-Performance Agility

In terms of performance, operations, and maintenance, the Rigid Fixed Wingsail (OW RF) offers 1.3 tonnes per day fuel saving in average and is particularly adapted with transocean transit voyages. Based on IMO data, for a ship sailing at 16 knots, 87% of the global trading routes exhibit apparent wind angles lower than 75°. This shows that Wind Assistance only makes sense if it produces thrust with headwind.

As such, our 2-element variable camber system differentiates by its thin and aerodynamic profile which generates positive thrust starting at 5° apparent wind angle. This agility is an essential feature for vessel facing unpredictable routes and headwinds.
