Germany’s Fehn Ship Management (FSM) has begun trading a multipurpose (MPP) vessel with an Eco-Flettner rotor sail after it completed sea trials in June.

FSM managing director Matthias Hesse tells TradeWinds that at the end of the one-year project, the company will decide whether to keep the 37-tonne rotor sail on the 4,250-dwt Fehn Pollux (built 1997) or use it on another ship.
