---------ABOUT THE VIDEO---------
This video was originally uploaded to our other channel, Casual Navigation, back in 2018.
An "in depth" look at Rule 8 of the International Regulations for Preventing Collisions at Sea, the COLREGS. The COLREGS are the rules of the road that vessels must obey at sea to avoid collisions.
Rule 8 covers "Action to Avoid Collision". In this video I go into detail about the rule and give examples of how to apply the rule at sea.
---------RULE 8---------
Rule 8: Action to avoid collision
(a) Any action taken 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 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.
(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 vessels are approaching one another so as to involve risk of collision.

Great class 👍 💯
thank you for your videos, im preparing for an interview and exam, this should be a good review for me
Really appreciate ur videos💯👍
His examples are great! well worth your time even if you know your rules.
Always good to brush up now and then
very useful video
Good job
Good clarity of collision avoidance. I have to say my years on the sea I have always had situational awareness in possible collision scenarios. I learned at an early age to err on the side of safety at sea and to follow also the Law of Tonnage ( unwritten Rule to
allow the larger vessel adequate sea room for manovering especially in restricted channels and close quarter operations)
Captain E Kilmaine
can you explain the "err on the side of safety at sea"
I use these video's in my class.
When there is a ROC in a crossing situation in tss or narrow channel do i have to state 17,15,8,9,18( if cbd) and 10. How do i structure my answer?
Just base your answer on rule 15 and further support it with rule 8 and 16/17. Under normal situation.
@@donnongkit39229 hi bro
what is the difference between passage and safe passage ?
Could you explain the last two points to me I tried to understand them but still can’t get them and also what’s the difference between them too
Hi Sir, can you explain to me why do you think it's better for the bulk to alter her course 90° to starboard instead of 90° to port?
In my opinion, it's better to alter to port and then to pass astern. Thanks, for the video and for your time =)
Just watch video till the end, there is explanation of that. :)
@@erffinek Yes but still. If the container vessel is conditioned by her draft, the green bulk carrier needs to give her way regardless the fact that the container vessel is on her PS - As per rule 18 d) - All vessels in normal conditions must stay clear from vessels conditioned by their drafts (which is the case of the container vessel). So I agree with TheArena7 and the best in this case and assuming we are in open sea and no more vessels around is - turn bold to port and pass clear astern.
Francisco Pessoa There are two reasons why the bulk carrier should not turn to port. 1) The container ship may slow down or stop as it is the giveaway vessel. 2) Or the container ship may turn to starboard to avoid collision as she would be expecting the bulk carrier to turn to starboard or Stand on (hold course and speed) as the rules require. The container ship would not be expecting the bulk carrier to turn to port. A turn to Port by the bulk carrier puts the risk of collision up not down.
@@roybennett3780 ok and what about rule 18 d) i)? It says that all vessels not RAM must (if conditions allow) to not stay in the way CBD vessels right? The container vessel knows she fits in that caregory. So why is it so wrong from them to think we will comply with rule 18?
I don´t like the ideia of turning to port too because that is turning against her but still, if she does not alter course because she is CBD and we have the space why not passing astern from her by rule 18 instead of waiting her to manouver by rule 15? And then make a 90º course alteration to SB.
My doubt is just about the fact that the container vessel is a CBD vessel. If not, no question at all.
Francisco Pessoa if the CBD is far away on port side crossing then you would alter to port passing stern, she might slow down for you. if the CBD is close then you would alter to stb or slow down. This depends on its speed and if in a narrow channel. CBD can only slow down it cannot move out of the way so it all depends on your ship in respect to hers.
Please advise.
Situation CBD on port side shown by surveyor..
What action..??
1. Early action alter course to port n pass her stern..
2. Reduce speed in ample time and allow her to pass ahead.
3. Alter course to starboard, parallel to CBD and reduce speed allow her to go ahead and then pass her stern..
Different surveyors different ideas.. Last time I answered 2. And he failed me saying I sud have altered to port for CBD n said i have no knowledge of rule 8f.
Answer 3. CBD is still a PDV, so you never alter to P for a PDV on Port Bow per Rule 15. Bear in mind that if she is uncertain of your action, the CBD vessel may alter to STBD, i.e. resulting in a head-on if you've altered to P.
This is assuming that Risk of Collision has been established
@@richardvincent5358 Thanx
I think 1 is right, rule no 18 overrides crossing situations isn't it ?
@@richardvincent5358 but if you are far away and risk of collision doesnt yet exist, you can alter to port as long as rule 17 says you cant alter to port if vessel on your port side in case when Risk of Collision already exists? right?
07:11 paragraph 3 of Part F
How the stand on vessel get to know that giveway vessel is CBD.?
By the day shape cylinder shown and 3 red all round lights ?
why is it obvious that the blue vessel should yield to the green vessel? guess I missed that part, but unfortunately that's the part I was trying to understand
You always give way to vessels crossing on your right.
Please I need short note on this rule please is there any one who can answer me I’ll be glad
Please
Sir what is the meaning of impend in rule 8?
Obstruct ..... "to not allow"
You mean impede ? It means obstruct. Not to impede means not to obstruct
Ww
Sir my 8 point is not clear
