Nothing in these Rules shall interfere with the operation of special rules made by
an appropriate authority for roadsteads, harbours, rivers, lakes or inland waterways
connected with the high seas and navigable by seagoing vessels. Such special rules
shall conform as closely as possible to these Rules.
PART A - GENERAL
Rule 1
Application
These Rules shall apply to all vessels upon the high seas and in all waters
connected there with navigable by seagoing vessels.
PART A - GENERAL
Rule 1
Application
Nothing in these Rules shall interfere with the operation of any special rules made
by the Government of any State with respect to additional station or signal lights,
shapes or whistle signals for ships of war and vessels proceeding under convoy, or
with respect to additional station or signal lights or shapes for fishing vessels engaged
in fishing as a fleet. These additional station or signal lights, shapes or whistle signals
shall, so far as possible, be such that they cannot be mistaken for any light, shapes or
signal authorized elsewhere under these Rules.
PART A - GENERAL
Rule 1
Application
Traffic separation schemes may be adopted by the Organization for the purpose of
these Rules.
PART A - GENERAL
Rule 1
Application
Whenever the Government concerned shall have determined that a vessel of
special construction or purpose cannot comply fully with the provisions of any of these
Rules with respect to the number, position, range or arc of visibility of lights or
shapes, as well as to the disposition and characteristics of sound-signalling appliances,
such vessel shall comply with such other provisions in regard to the number, position,
range or arc of visibility of lights or shapes, as well as to the disposition and
characteristics of sound-signalling appliances, as her Government shall have
determined to be the closest possible compliance with these Rules in respect to that
vessel.
PART A - GENERAL
Rule 1
Application
Nothing in these Rules shall exonerate any vessel, or the owner, master or crew
thereof, from the consequences of any neglect to comply with these Rules or of the
neglect of any precaution which may be required by the ordinary practice of seamen,
or by the special circumstances of the case.
Rule 2
Responsibility
In construing and complying with these Rules due regard shall be had to all
dangers of navigation and collision and to any special circumstances, including the
limitations of the vessels involved, which may make a departure from these Rules
necessary to avoid immediate danger.
Rule 2
Responsibility
(A amended paragraph (a) and a new paragraph (m) shall enter into force on _, as amended by Resolution A.919(22))
29 November 2003

exceptional circumstance is unable to manoeuvre as required by these Rules and is
therefore unable to keep out of the way of another vessel.
‘vessel not under command’
means a vessel which from
the nature of her work is restricted in her ability to manoeuvre as required by these
Rules and therefore is unable to keep out of the way of another vessel.
‘vessel restricted in her ability to manoeuvre’
The term ‘vessels restricted in their ability to manoeuvre’ shall include but not be
limited to;
(i) a vessel engaged in laying, servicing or picking up a navigation mark,
submarine cable or pipeline;
(ii) a vessel engaged in dredging, surveying or underwater operations;
(iii) a vessel engaged in replenishment or transferring persons, provisions or
cargo while underway;
(iv) a vessel engaged in the launching or recovery of aircraft;
(v) a vessel engaged in mineclearance operations;
(vi) a vessel engaged in a towing operation such as severely restricts the towing
vessel and her tow in their ability to deviate from their course.
’ means a power-driven vessel which
because of her draught in relation to the available depth and width of navigable water,
is severely restricted in her ability to deviate from the course she is following.
‘vessel constrained by her draught
means that a vessel is not at anchor, or made fast to the
shore, or aground.
‘underway’
’ of a vessel mean her length overall and greatest
breadth.
‘length’ and ‘breadth
Vessels _ to be in sight of one another only when one can be
observed visually from the other
shall be deemed
means any condition in which visibility is restricted by
fog, mist, falling snow, heavy rainstorms, sandstorms or any other similar causes.
‘restricted visibility’
means a multimodal craft which, in its
main operational mode, flies in close proximity to the surface by utilizing surface effect action.
‘Wing-In-Ground (WIG) craft’
Rules in this Section apply in any condition of visibility
PART B - STEERING AND SAILING RULES
SECTION I-CONDUCT OF VESSELS IN ANY CONDITION OF
VISIBILITY
Rule 4
Application
Every vessel shall at all times maintain a proper look-out by sight and hearing as well as by all
available means appropriate in the prevailing circumstances and conditions so as to make a full
appraisal of the situation and of the risk of collision.
Rule 5
Look-out
Every vessel shall at all times proceed at a _so that she can take proper and effective action
to avoid collision and be stopped within a distance appropriate to the prevailing circumstances and
conditions.
Rule 6
Safe Speed
In determining a safe speed the following factors shall be among those taken into
account:
(a) By all vessels:
(i) the state of visibility;
(ii) the traffic density including concentrations of fishing vessels or any other vessels;
(iii) the manoeuvrability of the vessel with special reference to stopping distance and turning
ability in the prevailing conditions;
(iv) at night the presence of background light such as from shore lights or from back scatter
of her own lights;
(v) the state of wind, sea and current, and the proximity of navigational hazards;
(vi) the draught in relation to the available depth of water.
In determining a safe speed the following factors shall be among those taken into
account: (b) Additionally, by vessels with operational radar:
(i) the characteristics, efficiency and limitations of the radar equipment;
(ii) any constraints imposed by the radar range scale in use;
(iii) the effect on radar detection of the sea state, weather and other sources of interference;
(iv) the possibility that small vessels, ice and other floating objects may not be detected by
radar at an adequate range;
(v) the number, location and movement of vessels detected by radar;
(vi) the more exact assessment of the visibility that may be possible when radar is used to
determine the range of vessels or other objects in the vicinity.
Every vessel shall use all available means appropriate to the prevailing circumstances and
conditions to determine if risk of collision exists. If there is any doubt such risk shall be deemed to
exist.
Rule 7
Risk of Collision
Proper use shall be made of radar equipment if fitted and operational, including long-range
scanning to obtain early warning of risk of collision and radar plotting or equivalent systematic
observation of detected objects.
Rule 7
Risk of Collision
Assumptions shall not be made on the basis of scanty information, especially scanty radar
information.
Rule 7
Risk of Collision
In determining if risk of collision exists the following considerations shall be among those taken
into account:
(i) Such risk shall be deemed to exist if the compass bearing of an approaching vessel does
not appreciably change;
(ii) such risk may sometimes exist even when an appreciable bearing change is evident,
particularly when approaching a very large vessel or a tow or when approaching a vessel
at close range.
Any action to avoid collision shall be taken in accordance with the Rules of this Part and shall, if
the circumstances of the case admit, be positive, made in ample time and with due regard to the
observance of good seamanship.
Rule 8
Action to avoid Collision
Any alteration of course and/or speed to avoid collision, shall, if the circumstances of the case
admit, be large enough to be readily apparent to another vessel observing visually or by radar; a
succession of small alterations of course and/or speed should be avoided.
Rule 8
Action to avoid Collision
) If there is sufficient sea room, alteration of course alone may be the most effective action to avoid
a close-quarters situation provided that it is made in good time, is substantial and does not result in
another close-quarters situation.
Rule 8
Action to avoid Collision
) Action taken to avoid collision with another vessel shall be such as to result in passing at a safe
distance. The effectiveness of the action shall be carefully checked until the other vessel is finally
past and clear.
Rule 8
Action to avoid Collision
If necessary to avoid collision or allow more to assess the situation, a vessel shall slacken her
speed or take all way off by stopping or reversing her means of propulsion
Rule 8
Action to avoid Collision
Rule 8
Action to avoid Collision
(i) A vessel which, by any of these Rules, is required not to impede the passage or safe
passage of another vessel shall, when required by the circumstances of the case, take
early action to allow sufficient sea room for the safe passage of the other vessel.
(ii) A vessel required not to impede the passage or safe passage of another vessel is not
relieved of this obligation if approaching the other vessel so as to involve risk of collision
and shall, when taking action, have full regard to the action which may be required by
the Rules of this part.
(iii) A vessel the passage of which is not to be impeded remains fully obliged to comply with
the rules of this part when the two vessels are approaching one another so as to involve
risk of collision.
) A vessel proceeding along the course of a narrow channel or fairway shall keep as near to the
outer limit of the channel or fairway which lies on her starboard side as is safe and practicable.
