Seamless Integration &Optimal Deck Utilization

Featuring a modular and lightweight design, our Lowerable Fixed Wingsail (OW LF) provides a cost-efficient solution for Shipowners and Shipyards looking for a minimal deck footprint. Whether you are building a Ro-Ro, ROPAX or Passenger ship, the Lowerable Fixed Wingsail’s design adapts seamlessly to various maritime configurations and guarantees excellent port maneuverability.

Robust, fully electrical and low-maintenance, the Lowerable Fixed Wingsail (OW LF) has an expected lifespan of 25 years, including a replaceable wingsail every 5 years, to ensure optimal performance throughout its operational lifetime and a strong payback.

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.
