Safe Speed, PDV have engines ready for immediate manoeuvre.

Have Due regard for Section 1 Rules: 5Look Out 6Safe Speed 7Risk of Collision 8Action to Avoid

Detect another vessel by radar alone - determine, ROC, take early action (cse/speed):

• Avoid A/C Port for Vessel Fwd of beam (other than a vessel being overtaken)
• Avoid A/C towards a vessel abeam or abaft the beam

Unless determined ROC does not exist, hear a fog signal fwd of the beam, or cannot avoid Close Quarters situation forward of beam

• Reduce speed to minimum steerage, take all way off if necessary.
• Navigate with extreme caution until danger of collision over.

Question 2

Answer 4

Nav Lights
Sound Signals
Master on bridge (expect to be informed)
-Increase manning
Inform ER
-Engines ready for immediate man
-Steering pumps ready
Reduce Speed
-Should be able to stop within the distance of visibility
-Allows more time to assess ROC and detect other vessels
Post Lookouts
-Sight Hearing (open bridge doors) Radar AIS Echo Sounder VHF 
Hand Steering
Check V/L Position
Ensure W/T Doors are secure.

Question 5

What do you understand by no to impede?

Answer 5

Navigate in way such that it will not lead to a risk of collision or close quarters situation. Will not cause other vessel to take avoiding action as per Collision Regulations.

NUC, RAM, Vessel engaged in fishing or trawling

Question 7

Answer 7

Powerdriven Vessels (Towing, CBD, Pilot)
Sailing Vessels

Question 8

Which vessels can you not tell the length of?

Question 9

Explain Meaning of Rule 2:

Answer 9

First and foremeost, whatever you do, don’t have a Collision or an Allision.
If you do you will be at least part responsible.

Master is liable for the consequences of not complying with the rules
Master is liable for not following good seamanship
Master is liable for not taking into account special circumstances.
- There are many special circumstances
- Must also take into account limitations of vessels.

We are not exonerated from liability if we follow the rules and have a collision.

A vessel may depart from the rules to avoid immediate danger; we should also be aware that other vessels may make departure from the rules.
