Ships requiring medical attention are required to fly the flag signal "LIM" during the day and
to flash 'Q' on their morse lamp by night when approaching Gravesend, both signals meaning
''Medical Officer required".
The light signals to be used by ships at night as amended in the Public Health (Ships) Regulations,
give rise, in the Port of London, to some difficulty owing to the fact that the red light is
already in use, either singly or combined with the white, by petroleum vessels and also by the
cross-river ferries. The matter is further complicated by the fact that the white signal is used to
call the Custom's launch on the approach of a vessel in the Gravesend Reach.
Consequently the flashing of 'Q' by morse lamp at night still continues but a number of
Masters are flying the red over white signal prescribed in the 1952 Regulations.
