The flag is described as red with a white disc and outlined H. Rosanoski considers the FOTW proportions incorrect: a photograph of Hanseatic Trader on 8 January 2007 shows a normal rectangular flag.
Hanseatic Scout’s starboard funnel and Hanseatic Spring’s port-side funnel show mirrored logos so that the depicted flag points forward on both sides. The blue shading emphasises the flag’s folds and, like the H’s shading, changes sides, as a close view of Hanseatic Trader on 5 June 2013 shows.
