The original flag is green with a large white serifed F, seen in the cloth outside the head office as well as in the website drawing. A helmet logo is lighter, corresponding to the source’s F371 reference; this older form still appeared in the website’s 2011 photographs and at deliveries probably dated 2008. Sturdy Falcon’s September 2006 funnel was very light yellow, without a black top. Speedy Falcon in September 2008 had a more conventional but tall F, a very broad band and a narrow black top.
The later flag retains a white F on green, but places the letter on a red six-pointed star formed from two equilateral triangles, with a point downwards. The green is lighter and more yellowish in the revised website logo. Its actual shade remains uncertain: some funnel photographs suggest darker green, some website photographs the brighter shade, and the images-section logo is duller. The website change occurred between 6 June and 4 September 2007.
The towage subsidiary apparently retained the plain green flag with white F. Falcon 62 is photographed in November 2005, and website photographs, including a 2006 view of the tug flying the flag, support continued use of the old design.
Sturdy Falcon shows this new funnel mark on 5 June 2011. Photographer Geir Vinnes reported Speedy Falcon still carrying the old mark in November 2010, but Sturdy Falcon carrying the new one in December; he therefore suggested that updating began late in 2010.
