- Definition of true bearing and relative bearing. Method to convert true bearing into the relative bearing and vice versa.
** CORRECTION @ 6.43 onward, relative bearing = -150 or 210 **
A small trick I would like to share, just remember “SHIRT”. Ship’s head (SHI)+ Relative bearing (R) = True bearing (T)
It's really helpful,thanks alot .

@@viditrawat1074 Not only helpful it's the right way! ships head in true degrees + relative bearing = true bearing. N.B.: You may have to subtract 360...For example, Ship heading 250 true + rel bearing of 315 degrees = 565 degrees - 360 = true bearing of 205 degrees. that can now be plotted.
Sir you explained very nicely. Feeling very satisfied
Thanks.
Hello Mr Sailorstube. I would like to thank you very much as all of your videos have been extremely helpful for my studies for my Master under 500GT/ Second Mates Ticket. Especially the Celestial Navigation and the Stability. Thank You Thank You Thank You :)

I thinks there's a little mistake there in the end.. True Bearing= 100 deg. T/Co= 250. That makes the relative bearing -150 plus 360 to make it positive which makes 210 deg. but still a very good lesson, cheers!

Thank you very much for noticing the same. Well, you are right and same has been corrected using speech bubble. Appreciate your attentiveness.
Relative bearings are measured clock-wise or anti-clockwise and up to 180 degrees only, in this case it is -150 or 150 degrees R to the port.
Ive noticed the same
I agree with that case... It supposed to -150 is the value of Relative Bearing... But anyway, we have learned for this video... Thanks and credit to the owner...

If the object is on your port bow, is it 45 degree relative bearing?
The art of complicating something simple.

@@KUNDANKUMAR-ik7ft What the hell kind of an answer is this ?
Bearings can only be calculated on a flat stationary plane, thank you for proving this point, excellent!
Wrong.. flattard

Sir, I have spotted a mistake in your video: 2:13. Relative Bearing should be measured from Ship head CLOCKWISE. Greetings
Thanks
Although i was studying for aviation.It helped me understanding concept.
Geet Sapra the same for me hahah, the video helped me a lot as well

Demonstrate the proper procedure in reporting bearings and sightings of objects on the compass repeaters?
Very well explained ♥
Please explain me about course and heading in detail
3:50 What do you call on this part?
2:15 The relative bearing in this part is wrong right? It should start from the ship's head in a clockwise direction to the line of sight of an object as what you have said.
Im also confused. Additional question. If the object is 45 degree on your portside. Is it not a relative bearing 45 degree?
it cleared my concept. thnx

Is relatively bearing always given? 210 during the last part of the video

Sir any video how to calculate eta.when speed and distance between two places is given.and journey starts.time also given. Like, start journey at 11 am 0340 hrs dist.1888nm spd 10 kt

at 5:28 how'd you get the 210 degrees? is it given?
yes it is bro
For 2nd mate/DNS/Bsc NS prepration join kundan patna #kundanpatna
-150+360=210
Excelllent
Great job done. Kindly compare in the last part of the video about conversion of bearing from True bearing to Relative bearing and vice versa. Thank you.
Thanks for the appreciation. The last example has some typo error which was corrected with TH-cam annotation, which may not show on all devices. Nevertheless, correct relative bearing is 210 instead 200 .
Thank you very much and more power.
For 2nd mate/DNS/Bsc NS prepration join kundan patna #kundanpatna
very nice video ........... very helpfful ....... just a small correction @ 6:48 mins - the relative bearing = 150 deg and not 160 deg.
Danish Pawne yea, I noticed as well. Cos was not matching with my maths kkk
Nice video though
Thanks I thought I was going mad

How.to.get relative bearing if the given is true.heading
For second mate/DNS/Bsc NS prepration join kundan patna #kundanpatna
how do you get the relative bearing 210°?
that's my question too!
relative bearing can be obtained with the help of gyro compass in ship.

Hello sailorstube, i'd like to tell you that you are doing a great job and i strongly appreciate your efforts.
I have a small doubt and would be grateful if you clear it.
My question to you is :-
How can i find true north on a ship and also the true direction of my ship's head?
You can find true north with the help of correct gyro compass. Alternatively you can establish north direction with the help of Polaris or Pole star , which approximately ( with in a degree) lies in north direction. So ships true direction is the clock wise angle from north direction to the ship heading or fore and aft line of ship .

Relative BRG= ( (-)160° )
How does that came?
Kindly Explain
It suppose to be -150° right
For second mate/DNS/Bsc NS prepration join kundan patna #kundanpatna
Tb100-tc250= -150+360=rb210 ?
Yeah thats correct
For second mate/DNS/Bsc NS prepration join kundan patna #kundanpatna
Last One You Say Wrong
True Bearing = 100°
True Course = 250°
= -150° + 360°
Relative Bearing = 210°
