Rule 8 - Action to avoid collision


Rule 8 - Action to avoid collision

(a) Any action taken to avoid collision, 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 sufficient sea-room, alteration of course alone may be the most effective action to avoid a closequarters situation provided that it is made in good time, is substantial and does not result in another closequarters situation.

(d) 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.

(e) If necessary to avoid collision or allow more time to assess the situation, a vessel shall slacken her speed or take all way off by stopping or reversing her means of propulsion.

(f) (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 vessel are approaching one another so as to involve risk of collision.

Questions & Answers


Q1. What 4 actions can you take to avoid a collision?
A1. Action to avoid collision:
(i) an early and bold alteration of course, as long as you do not put your vessel into another close quarter situation/risk of collision with another vessel
(ii) slow your vessel down
(iii) stop your vessel
(iv) come astern with your vessel

Q2. Why are you always making an alteration of course, why do you not stop your vessel?
A2. To make sure the risk of collision/close quarter situation is taken out, also the other vessel ill see the change of aspect of your vessel (Visually and by radar)

Q3. If you make an alteration of course, what have you to watch out for?
A3. That you don not put yourself into a close quarter situation with another vessel.

Q4. If you make an alteration of course, why is it dangerous to make a series of small alterations?
A4. Because you could go into a close quarters situation/risk of collision

Q5. If you're unsure about what to do in a situation, what's the best thing to do?
A5. Slow your vessel down, best to stop your vessel altogether.

Q6. Discuss how action to avoid collision should be taken.
A6. Action to avoid collision :

In accordance with the Rules, positive, made in ample time, with regard to good seamanship.

Q7. In the case of Q6, what does good seamanship means?

Q8. What do you understand by "in ample time"?
A8. In most cases, when risk of collision exist it is easy to determine HOW we should maneauver. But WHEN we one to take action it is a bit more complex and depends to a large extend, on existing circumstances:


The size and speed of the vessel involved, the manoeuvering characteristics (turning circle, stopping distance), type of activities vessel engaged (towing, fishing, dredging), sea room, presence of hazard of navigation, state of sea and weather condition to be considered.

Any action to avoid collision should rather be taken earlier rather than too late especially on large vessel.

A19. As officer of the watch (OOW) you must constantly be aware of what is happening on your on vessel and what is going on outside your vessel around you.


This included:


1. On your own vessel.

You must constantly know your exact vessel position and be aware of all dangers to navigation you are going to encounter, such as banks, shallows, rocks, wrecks, buoys, etc.

It is a very bad practice when you sight a buoy to go and check on the chart which buoy that may be. When you take over the watch, you check your position on the chart and according to your speed, you determine the way you will run during the watch. You also study all dangers you may encounter. You then make a photostats copy in your mind of that portion of the chart which will allow you to anticipate what and when you will see and/or meet obstacles. You need to check and plot a new fix at a regular intervals.

You need to be well acquainted with the atmospheric and hydrographic elements during your watch.

You need to know direction and force of the wind and state of the sea at all times. The direction and speed of current.

At all times, check the depth of water available and check for shallows and banks. They can produce bank suction, squat or sheering which may influence steering capacity and reduce the speed.

If there is any risk of collision, check if the engines are ready for use and at night, check if your navigation light is burning. Also check is the radar is operational or at-least on stand by.

Make sure the assistance watch keeper is on the bridge so that you can immediately switch over from automatic to manual steering.


2. Outside the vessel around you.

When you see any potential treat or a definite risk of collision from other vessel, take the following precautionary measures:


i. Radar plotting for data acquisition - course and speed.
ii. Regular compass bearing.
iii. Check how the vessel behaving. Is the vessel is keeping a steady course or sheering.
iv. Sounding the appropriate sound signal or make light signal with aldis lamp.
v. Be aware of interaction between vessel if you are following a parallel course.

– Not carrying the correct lights and shapes

– Not sounding the fog signals

– Etc.

A7. Precautions required by good seamanship

– Check if the lights are really burning

– Avoid yawing when required to keep on course

– Answer any fog signal

– Keep clear of a vessel at anchor

– Reduce speed in shallow waters

– Avoid inappropriate use of mobile phones

– Act with your experience and common sense

– Etc.

Q8. Would you consider a give-way vessel at a distance of 5 nautical miles to be an immediate danger?
A8. No. But depending on the size, speed and course of the give-way vessel (which can be assessed on the radar), extra vigilance is required especially if your own vessel is also rather large and fast with a stopping distance of 2 to 3 nautical miles.
If at a distance of 2 to 3 nautical miles (depending on the circumstances) the give-way vessel does not show any incentive to alter course, I would start to take some precautionary measures such as calling the ship on VHF and sounding a warning signal. If the give-way vessel still does not react, I will, in due course, seriously consider to apply Rule 17 and take action myself, such as reduce speed, stop engine, apply astern propulsion and alter course.
If I do not feel confident about the situation because it looks too complex or I still lack of the necessary experience, I will immediately inform the master to assist me.

Q9. Would you consider a complete steering gear failure in narrow channel to be an immediate danger?
A9. Yes. As soon as the vessel is not under command (NUC), take all precautionary actions/measures such as showing the NUC lights or shapes and sounding the sound signal . . _ (U - You are running into danger). Reduce speed or stop the vessel by applying astern propulsion and hold the anchors ready to stop the vessel more drastically if necessary.

Q10. It is appropriate to make a personnel call on mobile phone while entering or leaving harbour?
A10. Refer to MGN 299 (M + F).
