What is rule 1?
Application
(a) These Rules shall apply to all vessels upon the high seas and in all waters connected therewith navigable by
seagoing vessels.
(b) Nothing in these Rules shall interfere in the operation of special rules made by an appropriate authority for
roadsteads, harbors, 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.
(c) 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 or shapes or whistle signals for ships of war and vessels
proceeding under convoy, or with respect to additional station or signal lights for fishing vessels fishing as a
fleet. These additional station or signal lights or whistle signals shall, so far as possible, be such that they cannot
be mistaken for any light, shape, or signal authorized elsewhere under these Rules.
(d) Traffic separation schemes may be adopted by the Organization for the purpose of these Rules.
(e) 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 number, position, range or arc of
visibility of lights or shapes, as well as to the disposition and characteristics of sound-signaling appliances, such
vessel shall comply with such other provisions in regard to number, position, range or arc of visibility of lights or
shapes, as well as to the disposition and characteristics of sound-signaling appliances, as her Government shall
have determined to be the closest possible compliance with these Rules in respect to that vessel.
Who do these rules apply to?
These Rules shall apply to all vessels upon the high seas and in all waters connected therewith navigable by
seagoing vessels. (Rule 1 part a)
Explain rule 2?
Responsibility.
(a) 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.
(b) 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.
What is a Vessel?
Rule 3
The word “vessel” includes every description of watercraft, including non-displacement craft and seaplanes,
used or capable of being used as a means of transportation on water.
What is a Power Driven Vessel
Rule three general definitions .
The term “power driven vessel” means any vessel propelled by machinery.
What is a Sailing Vessel?
Rule three general definitions .
The term “sailing vessel” means any vessel under sail provided that propelling machinery, if fitted, is not
being used.
What is a vessel engaged in fishing?
Rule three general definitions .
The term “vessel engaged in fishing” means any vessel fishing with nets, lines, trawls, or other fishing
apparatus which restrict maneuverability, but does not include a vessel fishing with trolling lines or other fishing
apparatus which do not restrict manageability.
What is a seaplane?
The term “seaplane” includes any aircraft designed to maneuver on the water.
What is a vessel not under command?
The term “vessel not under command” means a vessel which through some exceptional circumstance is
unable to maneuver as required by these Rules and is therefore unable to keep out of the way of another vessel
What is a vessel restricted in her ability to maneuver?
The term “vessel restricted in her ability to maneuver” means a vessel which from the nature of her work is
restricted in her ability to maneuver as required by these Rules and is therefore unable to keep out of the way of
another vessel.
What are the types of vessel’s can be RAM?
Rule Three
(i) A vessel engaged in laying, servicing, or picking up a navigational 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.
What is a vessel constrained by draft?
The term “vessel constrained by her draft” means a power driven vessel which because of her draft 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.
Can a Sailing Vessel be CBD?
No as rule three states its a PDV only
What does it mean as being underway?
The word “underway” means a vessel is not at anchor, or made fast to the shore, or aground.
What is making way?
A vessel moving through the water under her own power
What does in sight of one of another mean?
Rule three general definitions
Vessels shall be deemed to be in sight of one another only when one can be observed visually from the
other
What does restricted visibility mean?
The term “restricted visibility” means any condition in which visibility is restricted by fog, mist, falling snow,
heavy rainstorms, sandstorms and any other similar causes.
What is Part B of the rules?
The steering and sailing rules. Separated into:-
Section 1 which apply to all levels of visibility.
Section 2 which applies to vessels in sight of one another
Section 3 applies to vessels in restricted Visibility.
Section 1 - Conduct of Vessels in any condition of visibility.
Rule 4 - Application Rule 5 - Look-out Rule 6 - Safe Speed Rule 7 - Risk of Collision Rule 8 - Action to Avoid Collision. Rule 9 - Narrow Channels Rule 10 - Traffic Separation Schemes.
Rule 5?
Look-out
Every vessel shall at all times maintain a proper look-out by sight as well as by 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.
What is a safe look out?
Rule 5
Look-out
Every vessel shall at all times maintain a proper look-out by sight as well as by 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.
Safe Speed?
Rule 6
Safe Speed
Every vessel shall at all times proceed at a safe speed 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.
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 manageability 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 from her own lights;
(v) The state of wind, sea and current, and the proximity of navigational hazards;
(vi) The draft in relation to the available depth of water.
(b) Additionally, by vessels with operational radar:
(i) The characteristics, efficiency and limitations of the radar equipment;
(ii) Any constrains 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.
