C507 is a red swallowtail with an eight-pointed white compass star. Loughran says the funnel predates the flag and dates the first flag to 1963, although the C507 drawing is attributed to US Navy 1961; the chronology is not reconciled.

A starboard photograph of Green Ridge on 27 May 2008 confirms the black-topped funnel. Mitchell also records its use by A/S Mosvold Shipping Co. on bareboat charters. The FOTW flag follows Brown 1995.

C509 adds black lettering to the star: a large C encloses a smaller G, which in turn encloses the start of the smaller word LINES. Rosanoski saw it ashore at Lyttelton’s Time Ball station for Greenwave on 28 January 1989. It appeared swallowtailed, but another sighting described a rectangle; it may be a shore advertising flag. The star was enlarged in the drawing to make the lettering legible.

The C803 funnel follows Green Lake and is assumed to bear only the diamond. Its flag comes from the group website and is probably the flag recorded as C509.

C965 follows a portside photograph of Green Cove on 28 February 2007.

C966 follows Green Lake on 9 January 2005. Only the upper funnel is visible, so the expected buff base remains conjectural. This appears to be a later vessel of the name; the earlier Green Lake had C803 and a dark-blue hull.

C967 follows Green Point on 17 December 2004 and a sighting reported in March 2007.
