The blue flag has a very broad horizontal white band bearing a blue ring nearly touching the blue edges. Inside is a four-pointed star, its points halved vertically blue and white, charged with a white S; star and letter are outlined black. Nimbus was photographed flying it. The funnel has a white lower part, perhaps treated as superstructure, and top cowls which may be omitted from a conventional rendering. Marinus provides a close match to the illustration, although its band is less white than the circle.
