RULE 5 |
5. Look-out
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. |
|
|
Everyvessel shall at all times proceed at a safe speed so that she can take properand effective action to avoid collision and be stopped within a distanceappropriate to the prevailing circumstances and conditions. In determining asafe 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 othervessels; (iii). the manoeuvrability of the vessel with special reference tostopping distance and turning ability in the prevailing conditions; (iv). atnight the presence of background light such as from shore lights or from backscatter of her own lights; (v). the state of wind, sea and current, and theproximity of navigational hazards; (vi). the draught in relation to theavailable depth of water. |
(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 ofvessels or other objects in the vicinity.

7. Risk of collision
|
Risk of collision(a). Every vessel shall use all available means appropriate to the prevailing circumstances and conditions to determineif risk of collision exists. If there is any doubt such risk shall be deemed to exist.(b). Proper use shall be made of radar equipment if fitted and operational, including long-range scanning to obtain earlywarning of risk of collision and radar plotting or equivalent systematic observation of detected objects.(c). Assumptions shall not be made on the basis of scanty information, especially scanty radar information.(d). 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 approachinga very large vessel or a tow or when approaching a vessel at close range.

RULE 8. Action to Avoid Collision (a). 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.(b). 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. |
(c)If there is +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.(d). Action taken to avoid collision with another v/l shall be such as to result in passing at a safe distance.The action shall be carefully checked until the other v/l i past N clear.(e)If necessary to avoid collision or allow more time to assess the situation, a v/l shall slacken her speed or take all way off by stopping or reversing her means of propulsion.(i). A v/l which, by any of these Rules, is required not to impede the pssg or safe pssg of another v/l shall, when required by the circumstances of the case, take early action to allow +sea-room for the safe pssg of the other v/l.(ii). A v/l required not to impede the pssg or safe pssg of another v/l is not relieved of this obligation if approaching the other v/l 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 v/l the pssg of which is not to be impeded remains fully obliged to comply with the Rules of this part when the two v/ls are approaching one another so as to involve risk of collision. |

RULE 9
(a). 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.(b). A vessel of less than 20 meters in length or a sailing vessel shall not impede the passage of a vessel which can safely navigate only within a narrow channel or fairway.(c). A vessel engaged in fishing shall not impede the passage of any other vessel navigating within a narrow channel or fairway.
|
(d). A v/l shall not cross a narrow channel or fairway if such crossing impedes the passage of a v/l which can safely navigate only within such channel or fairway. The latter v/l may use the sound signal prescribed in Rule 34(d)if in doubt as to the intention of the crossing v/l.(i). In a narrow channel or fairway when overtaking can take place only if the v/l to be overtaken has to take action to permit safe passing, the v/l intending to overtake shall indicate her intention by sounding the appropriate signal prescribed in Rule 34(c)(i). The v/l to be overtaken shall, if in agreement, sound the appropriate signal prescribed in Rule 34(c)(ii) and take steps to permit safe passing. If in doubt she may sound the signals prescribed in Rule 34(d).(ii). This Rule does not relieve the overtaking v/l of her obligation under Rule 13.(f). A v/l nearing a bend or an area of a narrow channel or fairway where other v/l may be obscured by an intervening obstruction shall navigate with particular alertness and caution and shall sound the appropriate signal prescribed in Rule 34(e).(g). Any v/l shall, if the circumstances of the case admit, avoid anchoring in a NC.

Rule 10 Traffic separation schemes
(a). This Rule applies to TSS adopted by the Org and does not relieve any v/l of her obligation under any other rule. (b). A v/l using a TSS shall: (i). proceed in the appropriate traffic lane (ii)keep clear of a TSS line or separation zone; (iii) join or leave a traffic lane at the termination of the lane, but when joining or leaving from either side shall do so at as small an angle to the general direction of traffic flow (c).Avoid crossing traffic lanes but if obliged to do so shall cross on a heading as nearly as practicable at right angles to the general direction of traffic flow. (d). (i)Shall not use an inshore traffic zone when she can safely use the appropriate traffic lane within the adjacent TSS, However,v/s of less than 20M in length, sailing v/l and v/s engaged in fishing may use the inshore traffic zone. (ii). Notwithstanding subparagraph (d)(i)A v/l may use an inshore traffic zone when en route to or from a port, offshore installation or structure, pilot station or any other place situated within the inshore traffic zone, or to avoid danger. |
(e). A v/l other than a crossing vessel or a vessel joining or leaving a lane shall not normally enter a separation zone or cross a separation line except: (i). in cases of emergency to avoid immediate danger; (ii)Avoid fishing within a separation zone. (f). A vessel navigating in areas near the terminations of traffic separation schemes shall do so with particular caution. (g). A v/l shall so far as practicable avoid anchoring in a TSS or in areas near its terminations. (h). A v/l not using a traffic separation scheme shall avoid it by as wide a margin as is practicable. (i)Fishing v/l shall not impede the passage of any v/l following a traffic lane. (j). A v/l of less than 20M in length or a sailing v/l shall not impede the safe passage of a PDV v/l following a traffic lane. (k). A RAM when engaged in an operation for the maintenance of safety of navigation in a traffic separation scheme is exempted from complying with this Rule to the extent necessary to carry out the operation. (l). A RAM when engaged in an operation for the laying, servicing or picking up of a submarine cable, within a traffic separation scheme, is exempted from complying with this Rule to the extent.

12. Sailing vessels
|
(a). When two sailing vessels are approaching one another, so as to involve risk of collision, one of them shall keep outof the way of the other as follows:(i). when each has the wind on a different side, the vessel which has the wind on the port side shall keep out of the wayof the other;(ii). when both have the wind on the same side, the vessel which is to windward shall keep out of the way of the vesselwhich is to leeward;(iii). if a vessel with the wind on the port side sees a vessel to windward and cannot determine with certainty whetherthe other vessel has the wind on the port or on the starboard side, she shall keep out of the way of the other.(b). For the purpose of this Rule the windward side shall be deemed to be the side opposite to that on which themainsail is carried or, in the case of a square-rigged vessel, the side opposite to that on which the largest fore-and-aftsail is carried.

13. Overtaking
|
(a). Notwithstanding anything contained in the Rules of part B, sections I and II, any vessel overtaking any other shallkeep out of the way of the vessel being overtaken.(b). A vessel shall be deemed to be overtaking when coming up with another vessel from a direction more than 22.5degrees abaft her beam, that is, in such a position with reference to the vessel she is overtaking, that at night shewould be able to see only the sternlight of that vessel but neither of her sidelights.(c). When a vessel is in any doubt as to whether she is overtaking another, she shall assume that this is the case andact accordingly.(d). Any subsequent alteration of the bearing between the two vessels shall not make the overtaking vessel a crossingvessel within the meaning of these Rules or relieve her of the duty of keeping clear of the overtaken vessel until she isfinally past and clear.

14. Head-on situations
|
a). When two power-driven vessels are meeting on reciprocal or nearly reciprocal courses so as to involve risk ofcollision each shall alter her course to starboard so that each shall pass on the port side of the other.(b). Such a situation shall be deemed to exist when a vessel sees the other ahead or nearly ahead and by night shecould see the masthead lights of the other in a line or nearly in a line and/or both sidelights and by day she observesthe corresponding aspect of the other vessel.(c). When a vessel is in any doubt as to whether such a situation exists she shall assume that it does exist and actaccordingly.

15. Crossing situations
|
When two power-driven vessels are crossing so as to involve risk of collision, the vessel which has the other on herown starboard side shall keep out of the way and shall, if the circumstances of the case admit, avoid crossing ahead ofthe other vessel.
|
|
|
Rule 16Action by give-way vessel
|
Every vessel which is directed to keep out of the way of another vessel shall, so far as possible, take early andsubstantial action to keep well clear.
|
|
|
Rule 17 Action by stand-on vessel
|
(a).(i). Where one of two vessels is to keep out of the way the other shall keep her course and speed.(ii). The latter vessel may however take action to avoid collision by her manoeuvre alone, as soon as it becomesapparent to her that the vessel required to keep out of the way is not taking appropriate action in compliance with theseRules.(b). When, from any cause, the vessel required to keep her course and speed finds herself so close that collisioncannot be avoided by the action of the give-way vessel alone, she shall take such action as will best aid to avoidcollision.(c). A power-driven vessel which takes action in a crossing situation in accordance with subparagraph (a)(ii) of this Ruleto avoid collision with another power-driven vessel shall, if the circumstances of the case admit, not alter course to portfor a vessel on her own port side.(d). This Rule does not relieve the give-way vessel of her obligation to keep out of the way.

Rule 19 Conduct of vessels in restricted visibility
(a). This Rule applies to vessels not in sight of one another when navigating in or near an area of restricted visibility.(b). Every vessel shall proceed at a safe speed adapted to the prevailing circumstances and conditions of restricted visibility. A power-driven vessel shall have her engines ready for immediate manoeuvre. |
(c). Every vessel shall have due regard to the prevailing circumstances and conditions of restricted visibility when complying with the Rules of section I of this part.(d). A vessel which detects by radar alone the presence of another vessel shall determine if a close-quarters situation is developing and/or risk of collision exists. If so, she shall take avoiding action in ample time, provided that when such action consists of an alteration of course, so far as possible the following shall be avoided:(i). an alteration of course to port for a vessel forward of the beam, other than for a vessel being overtaken;(ii). an alteration of course towards a vessel abeam or abaft the beam.(e). Except where it has been determined that a risk of collision does not exist, every vessel which hears apparently forward of her beam the fog signal of another vessel, or which cannot avoid a close-quarters situation with another vessel forward of her beam, shall reduce her speed to the minimum at which she can be kept on her course. She shall if necessary take all her way off and in any event navigate with extreme caution until danger of collision is over.
