SJÖFARTSVERKET.

The blue swallowtail bears a yellow star emitting ten rays above a yellow foul anchor. The rays appear white in Nüsse’s scan but may also be yellow, while a greenish cast to the yellow may be an optical effect. Unlike the arms and funnel badge, the flag has no crown; both flag and funnel anchors have cables which the website logo lacks. No photographed ship was seen flying this departmental flag. If flown at sea, Rosanoski regards it as a house-flag equivalent, since the Swedish flag served as ensign.

Ale’s funnel badge has a sky-blue oval and apparently white outlines to the crown and oval, with white rays. The star is assumed white; a possible yellow tinge could be rust.

On Atle’s white background the sky-blue oval apparently lacks an outline. The crown outline is yellow and the charges inside the oval are white. The flag’s blue is darker than the funnel badges.
