Certain Liberian-registered vessels used the reversed-colour flag, according to Loughran; Marine News also records their distinct livery.
This funnel is recorded on the chartered Maersk Newport on 20 January 2006.
Van den Muijzenberg’s longer triangular variant, about 1:2, follows the handover of Mærsk Mc-Kinney Møller. A brief filmed view showed a very pale blue resembling the hull, but the photographic angle is awkward; he retained the established illustration shade rather than asserting a new one. Sache observed an elongated triangular flag at Maersk France’s Boulogne-Billancourt headquarters and suggested that proportions of 1:2 or longer might aid visibility from the street. A photograph cited by Mertens likewise showed a longer pennant; flag books may shorten them.
The rectangular variant is disputed. Lahav saw rectangular star emblems on Maersk-Sealand containers and suggested that they might also distinguish its ships. Rosanoski knew of no such flag and stressed that a logo does not establish flag use. Schneider was fairly sure the Hamburg branch used rectangular flags, probably 3:5, as well as pennants of varying proportions, with the same pattern and shade; he could not establish the legal entity concerned. Rosanoski subsequently considered possible rectangular use ashore and triangular use afloat, but headquarters photographs remained ambiguous. Neither the rectangular flag nor that distinction is confirmed.
