Rule 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 condition so as to make a full appraisal of the situation and of the risk of collision.
Questions & Answers
Q1. Describe rule 5 look-out?
A1. By keeping a good look-out using eyes, ears and by using all navigation aids including radios for listening out for navigation warnings, so you can appraise any situation ahead of you.

Q10. Summarize the points the relieving officer should consider when taking over the watch.
A10. Refer to MGN 315 (M) Paragraph 7.
Taking over the watch :
Verify vessel’s position
Confirm intended track, course and speed
Note any dangers to navigation
Be aware of tides, currents, weather, visibility, and eventual effects on course and speed
Note errors on gyro and magnetic compass
Note status of bridge equipment
Note settings of bridge/engine controls
Q11. Summarize the main elements to be considered with regards to the maintaining a proper look-out.
A11. Refer to MGN 315 (M) Paragraph 8.
Q12. Which precautionary measures should the officer of the watch take in restricted visibility?
A12. Refer to MGN 315 (M) Paragraph 10.
In restricted visibility
Comply with the Colregs with regard to:
Keeping a look-out
Sounding of fog signals
Safe speed
Engines ready for immediate manoeuvre
In addition:
Inform the Master
Ensure the look-out is posted at all times
Exhibit navigation lights
Operate and use the radar
Put engines on standby
Q13. When should you consider to proceed at a safe speed?
A13. Refer to MGN 315 (M) Paragraph 11.
Q14. Which precautionary measures should you take when your vessel at anchor?
A14. Refer to MGN 315 (M) Paragraph 12.
Vessel at anchor:
Determine and plot vessel’s position
Check if vessel is remaining at anchor
Have a proper look-out
Make inspection rounds periodically
Observe:
Meteorological conditions
Tidal conditions
State of sea
Notify Master and take measures if anchor drags
Q15. What are the duties of watchkeeper when navigating with pilot?
A15. Refer to MGN 315 (M) Paragraph 9.
Q16. In connection with look-out, what do you understand by "all available means appropriate"?
A16. All available means appropriate
Use a radar:
In clear visibility
In restricted visibility
In operation or on standby
In congested waters
A proper look-out is still compulsory
Must be properly adjusted
Careful choice of scale range
Good choice of mode display
Q17. Comment the use of VHF as a collision avoidance aid?
A17. Refer to MGN 324 (M + F) Paragraph 1 - 13.
Q18. What do you know about the use of Automatic Identification System (AIS)?
A18. Refer to MGN 324 (M + F) Paragraph 13 - 21.
Q19. What do you understand by "fully appraisal of the situation and of risk of collision"?
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.
