STENA A/B.

Stena’s flag has a red field with blue and white bands at the top and bottom. Ship photographs, Northern Marine’s designated flag image and the Nüsse table flag support equal widths for the blue and white bands. The white outline on some website logos probably separates the flag from a dark background, while blue diagonal dashes seem intended to suggest folds. Both S53 and S480 funnel forms are recorded. Photographs of Stena Vision and Stena Artica supply S997, and ship photographs support the S53 funnel for Concordia Maritime.

Brown 1982 shows a small white shape above the lower end of the S; Brown 1995 resolves it as a ship’s bow above a wavy white line, but leaves the wave disconnected from the letter. The company photograph and Nüsse flag show the ship on a narrow wave continuing through the S. Brown’s 1982 letter is broader. The photographed S996 flies against a sea background apparently showing a wake, suggesting use from an aft ensign staff. Both this form and the banded flag have been seen at sea; Rosanoski does not establish an exclusive rule.

The Collectors Corner “Type III” badge has uncertain colours: the flag, red field, S and ship appear edged in gold, with a gold wave. Rosanoski suspects these are decorative badge details that would be white on any corresponding flag. FOTW renderings based on his comments omit the ship and wave; he says a possible flag reconstruction should include both. The source also labels an image S1458 while discussing S1548.

Haws shows a broad red horizontal band bearing a white S between narrow white bands. Although initially questioned, Rosanoski considers its use in the P&O Stena flag evidence that it existed. The corresponding funnel is unclear from line drawings.

Stena Adventurer’s photograph confirms this funnel, with its accompanying flag traced to Brown 1982. A later Stena Europe photograph still shows the funnel. Stena Nautica’s close, low-angle starboard photograph does not show the blue base, which may simply be hidden.

This website flag logo probably represents S997, its apparent white border being an outline against the background.

Stena Atlantica’s June 2013 photograph shows a stern-superstructure logo and STENA BULK on the hull, although the vessel is listed under Stena Line Scandinavia. Rosanoski rejects the accompanying Northern Marine attribution; the funnel is S997 with a more conventional S.

Stena Feronia carries a plain red funnel after sale to Stena North Sea in February 2011. The reason for the plain colour is not established.
