EMSTANK GMBH.

The flag has large white italic E and T within black outlines. Its field is divided diagonally into black upper and lower triangles and light-blue hoist and fly triangles edged white. The white narrows towards the centre, where the triangle tips meet. The top and bottom edges have black outer and narrower white inner stripes. Emstank 8’s starboard photograph of 11 July 2009 shows the flag.

Emtank 12’s port-side photograph of 7 August 2008 supplies the funnel. The initials are upright on the funnel and on the website drawing, perhaps for readability. A table flag and real-flag sightings provide additional evidence.
