WINGSAIL

First lowerable system on the market

Specifically designed for Ro-Ro, PCTC* and Passenger vessels with no air draft limitation, our Lowerable Fixed Wingsail (OW LF) offers a perfect suitability for both retrofits and newbuilds projects, when tilt is not an option. Featuring a modular and lightweight solution, it boasts the best thrust-to-weight ratio and a small footprint, ensuring seamless installation and minimal impact on stability.

The Lowerable Fixed Wingsail (OW LF) stands out for unmatched performances with upwind conditions, providing the ideal solution when tilting is not an option.

High-Performance Agility

The Lowerable Fixed Wingsail (OW LF) offers 1.3 tonnes per day fuel saving in average. 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 which is essential for high speed vessels like Passenger vessels or Ro-Ro.
