The house flag is horizontally divided white–green–white, with fimbriation, and carries a green-on-white logo: a stylised F, which Mertens thought resembled a V, above small waves. The logo is shifted towards the hoist, correcting an earlier centred depiction. Dennis-F supplies the funnel reference; its yellow top is a cap not apparent in photographs of other vessels.
The company also flies a similar pennant, with the logo nearer the hoist. An auction example was approximately 0.50 by 0.75 m; Rosanoski also cites a photograph of Colin-F.
