No words to say how good is your explanation i really really appreciate very impressive and easy to understand the way you discussed the topic thank you sir for uploading this video
Was having a problem learning the radar plots.... and ended up searching for some explanations . This set of 3 videos simply cleared everything and I'm pretty much confident now. Thanks a lot, really appreciate for sharing the knowledge and making it look so simple !!!
I have been accessing dozens of youtube sessions to assist in this subject, this is definitely the best, well explained, diagramed, and delivered absolutely brilliant thankyou.
well explained!!! wowww. Capt. Clover explained it better than my instructor here on our university in my country (Philippines🇵🇭). This is why I love this channel, They are so good on making you understand the topic step by step, eventhough its in English where I struggle a bit on comprehending and speaking of, but I have still managed to understand the topic compared to how my former seafarer instructor discussed it to me, and he was speaking on our local language.
Captain Glover,I want to say to you many thanks,but many,many thanks for such a way to explane out these three steps of radar avoidance plotting.I have a radar book but it doesn't teach the minimum procedure of what to do or how to do it.God put you on the correct spot to clarify everything for me. I suggest that you should give the full celestial navigation class on this line,is not a bad idea.Think it over Captain,thank you once again.
thank you captain for this short explanation and training about radar plotting.wish you always share about any knowledge you have and making us being more professionall as like you
Very nice! Just started with radar plotting this semester. We havent learned about that minimum CPA range yet but very cool and logical to plot it like that :)
Hi Capt. Bob, I have just learnt this 3rd part though could you please tell me the formula used to work out the speed change of our own vessel? I get that we measure the distance though over what time?
The series of instruction is very explicit to understand for a new learner, I really appreciate captain. But I got one more question, we finally determined a new course (starboard) to avoid potential threat, I also realized ship is able to "slow down" if I don't want to adjust course, however, I was pondering if it will confront a new potential collision when I change course to port side along the ARML set by Captain Glover, or I can only starboard at all.
this is all great but what if you are supposed to take a new cpa and tcpa after you have changed course? and what if there are two vessels in that case?
It would appear that on this leg of the explination you switched the scale that you are using....you use the second range ring as the 2nm mark but really that is the 4. Is this the case or did I just get it wrong?
Next Day. I did this carefully in a large scale (1":nM) and got new course 56°T. Puzzled, I fiddled around with screen grabs and enlargements until I could measure Capt. Glovers rough sketch on the whiteboard. I read off 53°T. Anyone else working through the Radar and Mo-board examples on paper? This is a super series but I think there's probably a glitch in this final measurement (Own New Course to Steer).
He just picked up some course and then determined the speed reduction to that course, needed to have the 2nm CPA. Course could have been 015 and speed reduction would be higher. Or 035 and the speed reduction little less.
at about 10:50 it is explained. It is Caps own label for R prime. That is the point which defines maximum course change (ie. not slow down at all) to achieve New Relative Motion Line so keeping CPA as ordered. Hope this helps.
It's a random spot that you choose in order to maintain the CPA determined by the company or the Master. For example, in this case the CPA that we need to maintain is 2 nautical miles, so obviously we won't start changing our course when the other ship reaches that 2 nautical miles distance from us. We shall begin the change of course earlier,for example when the target reaches 3 nautical miles from us -like the captain does in the video- in order to maintain the preferable CPA.
your observance is true, hence why ARPA was developed, these video's are designed to assist the mariner in refreshing the traditional use of radar plotting, to renew Cert of Competency and/or learn plotting methods

Very clear and smart explanations sir especially with the M n ms
the best instructor ive known so far thumbs to this guy👍👏. watch from 1-3 and you'll have everything you need to know.
I have been accessing dozens of youtube sessions to assist in this subject, this is definitely the best, well explained, diagramed, and delivered absolutely brilliant thankyou.
I'm a Filipino seaman I really admire the explanation so far. Very clear and understood the explanation thanks
Simple, concise and no complicated explanations. Thank you Capt Bob!
Masterclass in how to explain something. You would happily pay good money to study under this gentleman.
Congratulations on your detailed and easy to understand explanation Captain Bob!! I'm more than grateful for this video. Thank you very much!
Well explained Capt. Bob. Was just looking to refresh my knowledge and found these videos. Excellent.
I am going to get my BS practical today, and I studied this all night. Thank you sir!
Your teachings and concepts are so amazing sir, thank you very much 🙏
Thank you so much Captain Bob sir, now i have cleared all the definitions and questions about radar plotting sheet.
This instructor is EXCELLENT ! Thank you.

Thank you for sharing the knowledge. Really impressive explanation.
Watched the 3 parts video. Strongly recommended. Excellent stuff!
YOU ARE AMAZING TO EXPLAIN IN SO DETAIL AND YOU ARE KIND ENOUGH TO PUT IT ONLINE
Best I have ever seen! He is awesome.
If only ALL teachers were like this Captain...
Great explanation. In one word... SUPER. Great job Kpt. and txs again for this.
An excellent series of videos on collision avoidance using radar. Thank you very much for sharing them.
Thanks a ton sir. Best explanation ever for RADAR plotting.Cleared all my doubts.
A very clear and efficient explanation - thank you for sharing this.
My mind fully grasped this information. Thank you so much captain.
You are a great teacher, well explained. Thank you
Watching these 9 years after posting and wish I had some sample problems with answers. Very interesting.
Excellent instruction! So clear and precise. Thank you so much.
I was so cofused with the training explanation but ive leared it from you sir. Thank you
thank you captain, now i learned how to plot this radar plotting, our instructor didn't teach as well. thanks a lot it ! :)
Thank you for this video.Incredibly clear and well taught.
thank you captain for this short explanation and training about radar plotting.wish you always share about any knowledge you have and making us being more professionall as like you
Many thanks! Very clear and easy to understand.

Excellent work thanks for teaching radar plotting captain
Thank you for this excellent tutorial! Specially the part with the speed reduction really helped me a lot!
Amazing video and way of teaching! Thanks
This instructor is excellent ! Thank you.
Thanks cap, great explanation
Thank you so much for good explanation sir
First class presentation
what a great explanation is that.Thank you sir.
Thank you very much sir. Really helpful. ⚓❤️⚓
thank you captain
I have learned different way to change the course but at the end both have same results.. about my new Speep it is rly new and smart way
Thankyou capt. Bob
Superbly explained, thanx alot
This 3 part series is a very good presentation of which I am appreciative.
We are glad that we could be helpful!
That was best information to understand thank u
Thank you Capt
thank you so much
It´s damn great.!!!
very good
Thanks Captain!!!! :)
Brilliant

Read COLREGS avoid altering to port
Thank u cap
I'm glady my AIS tells me all.this.
this is all great but what if you are supposed to take a new cpa and tcpa after you have changed course? and what if there are two vessels in that case?
What happened in case our vessel must changer her course to 110 degrees ?
DID KNOW INTERNATIONAL REGULATION WHICH STATE WE SHOULD USE RADAR PLOTTING SHEET?
perfect !
Sir can you explain how to Calculate New Time of CPA ?
Thank you😁❤️
Funny explanation!
It would appear that on this leg of the explination you switched the scale that you are using....you use the second range ring as the 2nm mark but really that is the 4. Is this the case or did I just get it wrong?
Remember relative and true courses ;)
I mic'd that off too. Im sure it was 4nM radius.
I reckon its because he is using what looks to be the 2:1 scale.
Next Day. I did this carefully in a large scale (1":nM) and got new course 56°T. Puzzled, I fiddled around with screen grabs and enlargements until I could measure Capt. Glovers rough sketch on the whiteboard. I read off 53°T. Anyone else working through the Radar and Mo-board examples on paper? This is a super series but I think there's probably a glitch in this final measurement (Own New Course to Steer).
If you had to turn to port, instead of starboard, would you draw in the "e" line in an equal and opposite direction from "r" ?
What wold be the New CTA time after changing the course to 043 T?
How about the maneuver time?
When your talking about changing both course & speed (11:56) you used 030 Where did 030 come from ?
He just picked up some course and then determined the speed reduction to that course, needed to have the 2nm CPA. Course could have been 015 and speed reduction would be higher. Or 035 and the speed reduction little less.
How to get mmx
Guys pls help why does the new course is 043 degrees??
how to get the BNCPA and TNCPA
Not sure why you've transferred your NRLM to ARLM and did all that extra stuff. Surely the angle Mx from RML to NRLM is your alteration of course.
Only looks like that cause re and me are similar. Imagine if re was longer. The angle it would swing by would be smaller.
what Rc means? is it true course?
at about 10:50 it is explained. It is Caps own label for R prime. That is the point which defines maximum course change (ie. not slow down at all) to achieve New Relative Motion Line so keeping CPA as ordered. Hope this helps.
Sir how do u get the Mx, got confused, thanks
It's a random spot that you choose in order to maintain the CPA determined by the company or the Master. For example, in this case the CPA that we need to maintain is 2 nautical miles, so obviously we won't start changing our course when the other ship reaches that 2 nautical miles distance from us.

how can I find P1RNG P1BRG and P2RNG P2BRG :) OC 010T OS 12kts
M1 2100h 055° 10nm
M2 2112h 055° 7nm :)
Tovi easy
tuon tuon ta guys ma laboratory si sir bwas.
Expectation.. only one or two vessel, realty especially china. 1000
