PART B - STEERING AND SAILING RULES SECTION I-CONDUCT OF VESSELS IN ANY CONDITION OF VISIBILITY Rule 4 Application
33
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
34
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
35
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.
36
In determining a safe speed the following factors shall be among those taken into account: (b) Additionally, by vessels with operational radar:

Rule 7 Risk of Collision
40
In determining if risk of collision exists the following considerations shall be among those taken into account:

41
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
42
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
43
) 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
44
) 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.

46
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.

Rule 9 Narrow Channels (fishing)
50

Rule 9 Narrow Channels
51
Rule 9 Narrow Channels
(i) In a narrow channel or fairway when overtaking can take place only if the vessel to be overtaken has to take action to permit safe passing, the vessel intending to overtake shall indicate her intention by sounding the appropriate signal prescribed in Rule 34(c)(i). The vessel to be overtaken shall, if in agreement, sound the appropriate signal prescribed in Rule 34(c)(ii) and take steps to permit safe passing.
