De Bock Maritiem C.V. / later Smaragd C.V.

The earlier funnel follows Smaragd: port-side funnel and flag on 24 March 2007, and starboard funnel on 18 August 2005 with the emblem pointing forward. The clearest flag photograph, dated 10 December 2006, also shows the Wagenborg manager’s flag and a third flag unidentified by Rosanoski.
