Whatever she is, she is marked with group flashing green tower buoy.
She is in 16 fathoms of water, with a sounding depth
to the hazard ( water cover ) of one fathom. It doesn't look like
a new map, but they may be marked in metres rather than fathoms.
The chart is in Fathoms issued in 1979, so not a small ship !
Treeve must have been looking at his Symbols and abbreviations used on charts issued by the Hydrographic department of the Admiralty!
