---------ABOUT THE VIDEO---------
This video was originally uploaded to our other channel, Casual Navigation, back in 2018.
In this video I show you how to complete a more advanced radar plot to find CPA, TCPA, Course, Speed and Aspect of a target vessel and then how to undertake a course alteration and calculate a new CPA and TCPA.
Learning how to complete a manual radar plot is an essential part of any maritime training, whether you are learning to navigate a supertanker or a sailing yacht. Knowing how the electronic equipment performs its calculations is vital so that you can understand its limitations.

This gave a new perspective to this Radar plot and helped me to understand the O prime position. Thanks
Instablaster.
Very nice and simple explanation, good job
Clear and concise ! thank you very much !
This video teaches the theory behind Course Alteration and what COLREG wants you to understand.
COLREG also wants you to be able to do this quickly.
You have to be familiar with the radar, radar parameters, tools such as EBL/VRM.
Great teaching, appreciated.
Could you please come up with tutorial on a delayed performance course alteration by the target vessel to find the new TCPA
Very helpful, thank you!
Superb channel 💝💝💝💝💝
We have a online class right now. And we need to plot but i dont know how. Thank you for the knowledgs but may i know how you do it in your computer?
About the own ship vector line, when our speed is 10kts so the vector length would 10NM? Did i get it wrong? How would I know the lenght of my vector?
hey, you’re measuring on the radar for 12 min. that’s why your vector is only 2 miles long, that’s the distance that you cover in those 12 min!
👍🏻
Please do video on speed and course alterations simultaneously by target vessel
Can you please make a video with on course and speed alteration with performance delay in the situation?
can you show how WO will be obtained?
video radar plotting: suddenly vessel stop at certain/ specific time. please !!!!
video on alteration of speed, please!
Sound to hard to do your way.
My first plot is my vessel is at centre. I mark a line for my bearing and speed.
I then plot the position of my target vessel.
6, minutes later mark my new position. I then mark the target vessel new position. If no change in bearing or speed of both vessels.i then can determine a possible collision point
I then determine the time to that point of both vessels.
I check with a third plotting of both vessels current position to see if any change in course or speed.of target vessel. I then determine close point and decide if course or speed change is required of my vessel. It's simple and it's easy to see what is happening.
Make sure you don't mix up relative and true plotting. If your radar is giving relative bearings and distance of the other vessel, your own vessel should remain at the centre.
Can someone explain CPA becoming 0 and tcpa having and answer,and when the target is in the same bearing and approaching what happens
Why use the 12 min plot? If you use a 6 min plot all the math is gone due to it being 1/10 of an hour...
And 12 min is 1/5 of an hour...
Same thing
These 3 points have a double cover 3 knuckle duster to cover the middle iron fist while at the samr time the rosary beads can become 3 balloon on the right as the top balloon can have the oval eye from yesterday on the left
the tail of the rosary beads can become the kraken horn to call in so the balloons can fly away or can be poped 😂
If you provided this video for entertainment purposes and "try" to be accurate, this means that this is a freaking unreliable and useless piece of crap and a pathetic excuse of a video. People who watch this are students who are taking online classes and want to make sure that they are doing it right because no one is lecturing them. If this is all entertainment for you, I don't find this funny. You should just take off these videos if they aren't reliable instead of spreading false information deliberately!
