Challenges
The shipowner Alizée was looking for a shallow-draft Ro-Ro vessel with an efficient and reliable Wind Assisted Propulsion System (WAPS) to operate on a transatlantic route. Design criteria included a light weight system and small deck footprint (2.5m) to match both the stability constraints and the cargo hold design.
Our value proposition
Our 363m² Lowerable Fixed Wingsail (OW LF) was selected as it offers fuel savings between 30% to 50% depending on wind conditions (typically 1.3 tonnes per day per wingsail).
It provides the highest thrust-to-weight ratio (59% ¹) of the market, guaranteeing stability and easy integration while maximizing commercial cargo space. It offers a large operating window with net propulsive power from 5° of apparent wind angle.
Last but not least, the wingsail’s geometry (11m wide) offers a natural roll damping effect which is particularly appreciated by the crew on such a shallow draft vessel. With no air draft limitation, the client opted for a reefable solution.
