Listing is due to full manoeuver speed (cca. 17.5 kts) and rudder 20 deg or full to the port. She's got the Becker Flap rudder which has excellent manoeuver capabilities (strong rate of turn) plus some other things that affects stability like metacentric height and small block coefficiency and therefore heavy list while turning. I believe this is departure from Antwerp and pilots must order a bigger angle to the helm due to narrow passage and high speed. It's not even unusual that ship's calculate a deviation of magnetic compass and therefore making a full circle, usually in Flushing Roads (Vlisingen).

Cheers.
