The Royal Northumberland Yacht Club is based in Blyth, UK.
As is well known, the club has a defaced Blue Ensign. The defacement is
called the Percy Lion. It is based on the statues of lions that adorn the
residence of the Duke of Northumberland, whose surname is Percy. It is a
stiff-tailed lion. The Lloyds Registers of Yachts show this ensign, but
their depiction of the Percy Lion is inaccurate, and (apparently) jarring to
members. It looks like a dog. Yes, the Lloyds Registers showed this picture
year after year. But it's not regarded as accurate by the club. The club's
website at
http://www.rnyc.org.uk/facility/ensign.html shows the Percy Lion
according to the club.
The club's burgee is shown at the same site. The club's burgee has been
the unwitting and unintentional victim of poor media depictions. I am a
stickler for first-hand sources, so I would recommend emailing the club,
attention Bruce Grant, and having this confirmed by the Club if there is any
doubt. The traditional and correct burgee according to the
Club itself (and as evidenced in some of my yacht registers; 1910, 1907,
1933) is black, with a red border around the top and bottom edge, but not at
the hoist. The Percy Lion is in the black portion, facing the hoist. Again,
the club website shows this. Due to some on-paper depictions
(and other non-fabric depictions), some people concluded the red border is
also included on the burgee's hoist. To quote the club's website, however,
"The traditional club burgee has red borders on two sides, as shown here. In
recent years variations of this traditional design have arisen." I visited
the club in 2007 and 2-border design is what is used.
Finally, there is a version --which exists only on the Internet and on some
old letterhead-- that places a narrow white fimbriation between the red
borders and the black. See, e.g., World Flag Database. This on-paper
'fimbriated version' simply arose (I was told) because the computer printing
media insisted on the white fimbriation (to keep the black from bleeding
into the red?). This "fimbriated" version is simply a printing anomaly; I
have never seen an actual flag that looks like this. However, it is making
quite an appearance in the media.
