Diving operations are indicated by flying one of
two nationally recognized "Diver Down" flags, or
navigation lights if at night. Either signifies
a danger area. Stay well clear of diving
operations because divers can easily stray from
the diving vessel.
International Code Flag "A" has several uses,
one of which is to designate diving operations.
The Inland Rules specifically require a boat,
when engaged in diving operations and thus
restricted in its ability to maneuver, to
display a rigid replica of the International
Code Flag "A". Exhibiting this signal invokes a
special right-of-way of this vessel over
essentially all other vessels. The key point is
restricted in the ability to maneuver.
Code Flag "A" is used only on a vessel. It
should never be displayed on a diver's float, or
raft.
However, it is the practice of nationals of
other countries to use the Code Flag "A" instead
of the flag shown below. If the Code Flag "A" is
seen on a diver's float or raft it should be
treated as meaning: Caution - Diver Down.
A red square flag with a diagonal white
stripe is also an accepted and recognized signal
meaning: Caution - Diver Down. This flag
is used on a vessel or on a diver's float, buoy,
or raft to indicate diving operations. When
divers are swimming free of the vessel, this
would be the logical flag to use. The flag
should be exhibited in rigid form. |
