A black-and-white photograph of Kronsprinsessan Ingrid confirms the funnel. Sources differ over whether the flag letters follow the diamond’s angles. Talbot-Booth specifies light blue, while FOTW’s version is very dark; the Bryggan images are indistinct.

Bryggan appears to show a second, lighter-blue flag with a white, yellow-edged saltire arm from upper hoist to lower fly. Rosanoski found no independent support for this variant and suspects that unclear printing may instead be intended to distinguish funnel markings with flag panels.

A postcard of Prinsessan Christina, chartered on the service in 1982, supplies the funnel but does not resolve its panel lettering. The cap badge gives gold GFL letters angled to the diamond, itself edged gold, with a darker gold than the bright yellow edging of the diagonal band. One website omits the blue funnel top. Marinart instead describes a white funnel with black top and a multicoloured GFL or other device.

The later Sessan design has a crowned mermaid. The cap badge shows a blue flag with a gold mermaid, but the funnel postcard appears to make the figure white over yellow sea; the website logo is also white with blue outlines and shading. Rosanoski questions the badge colours because he would expect flag and funnel to agree. The design was short-lived, giving way to Stena’s colours in 1982.
