proceeding at 6$ knots, was exhibiting not under command lights.
Mr Justice Brandon said:
There is no doubt that the Djeruda had been in some difficulties because of
the heavy weather but it seems to me to be difficult to say that she was even
partly disabled. She had the full use of her engines and steering . . . I think
that the Djeruda was well able to keep out of the way of the other ship
without great or unusual delay and that she had no business to advertise herself
as unable to do so.
(8) The term ‘vessel restricted in her ability to manceuvre’ is intro-
duced for the first time in the 1972 Regulations. A definition to cover
all vessels engaged in operations which restrict manceuvrability is
necessary as such vessels form one of the categories referred to in
Rule 18 which specifies responsibility for keeping out of the way.
In addition to vessels engaged in the special operations mentioned
in Rule 4(c) and (d) of the 1960 Regulations the following have been
included in the category of vessels restricted in their ability to
manceuvre:
a vessel engaged in handling pipelines
a vessel engaged in dredging
a vessel engaged in transferring persons or cargo underway
a vessel engaged in a difficult towing operation.
The lead-in sentence to sub-paragraphs (i)-(vi) was amended in
1981 to indicate that the list is not exhaustive. Vessels engaged in
other kinds of operation which restrict their ability to manceuvre as
required by these Rules may be considered to be in this category. A
vessel transferring spare parts necessary for repairs whilst underway
is intended to be included in the category mentioned in (g)(iii) as it
could be considered to be transferring provisions.
The term ‘minesweeping’ in sub-paragraph (v) was changed to
‘mine clearance’ by the 1981 amendments to include other opera-
tions such as minehunting.
(h) In 1968 IMO recommended (Resolution A 162 IV) that ‘deep
draught vessels’ in open waters, using channels which they would be
unable to leave without risk of grounding, should show the signals
which are not prescribed in Rule 28, so that they could be recognised
by other vessels.
At the 1972 Conference it was decided to include provisions relating
to the so-called deep draught vessels in the Rules. In considering how
