I am a Marine Nav-Comm-Controls service engineer who never sailed as crew, but sailed many times as a service engineer. I really love your videos as it gives me insight on how the crew use the systems we install, repair and survey... Thanks for your efforts, it is much appreciated!
Cheers Jannie
I'm graduating right now and I'm envious of all the students that are currently in their first years of uni and get to take advantage of your videos.
Thanks tutracrafty
I learnt the mnemonic ‘East is Least, West is Best’ during my private pilot training i.e. If the variation is east the magnetic bearing will be less than (least) the true bearing therefore subtract the variation from the true to get magnetic. The opposite being used if the variation is West.
I live in the UK so it makes very little difference at the moment - the local airfield currently has a variance 0.6 degrees West, but I know some places can have crazily high variances.
Great video! Love the content you’re putting out.
Thanks Robin!
Great comment, Robin! I learned the exact same thing in my private pilot training over here in the States, and it’s a funny illustration of the Law of Primacy (first learned is best learned) because now 44 years later as an airline pilot, that’s still how I remember it!
Excellent video!
@@HEDGE1011 🙀 no wonder the cloud looks like a red brick. No wonder the jummah people just want to pray and not show me their hand. Aka waterfall people aka limelight
My life has absolutely nothing to do with ships but I love learning about it! Thanks for being an engaging teacher
Thanks Sterling
@@CasualNavigationAcademy aka camfield aka rose compass can anyone see the relation in this? 🙀
Welcome back Sir, very happy you came back uploading new learnings.
As someone trying to get his 1600 mate (currently AB Unlimited). These videos have been helpful.
Nice tutorial! Straight to the point.
Clear and concise. Cheers.
I find your tutorials extremely helpful as they efficiently deliver information that is grounded in the experience. I welcome any tutorials, because your explanations are easy to follow.
Thanks Mojo. More are coming.
Very clear information and explanations on all your videos. Thank you so much.
The quality of videos is great. Thank you you! Looking forward for new episodes.
Thanks And. I'm hoping to keep them coming each week!
I really enjoyed this and I like the format. There is very little risk of me having to use this information, but I love being able to understand the black magic of navigation.
it's very unmagical when you think about it
a fix is to use the information you have based on what you can see and detect to determine where you are.
determine your compass error and engine speed to determine where you went since your last fix
study the weather to see how far you got pushed off the line from where you were too where you're going
and then correct for it.
you can get into the fine details, and it's easy to get bogged down in the specifics.
Thanks Jasper. Glad you enjoyed it!
@@averagejoey2000 I dunno seems like witchcraft to me
@@SterbsMcGurbs you can gain a complete understanding from Bowditch's American Practical Navigator. the text is voluminous, but leaves no mystery whatever
Awesome! I am so glad you are doing videos on chart use :D
A little chart-making tidbit, in my country, we try to put the roses in adequate positions/quantities that a 12" parallel rule will be able to work well for any position on the chart. Sometimes it is a real pain in the bum fitting them in!
That makes sense. I hadn't realised they were placed with such thought!
According to the turkey rose its looks more like a vagina but what do I know
Remembering those days where ECDIS is not yet around.
Really like this style of video, would love to see more. I'm an amateur weekend sailor with a small coastal cruising boat who just potters near the UK coast and does the occasional bareboat charter holiday around Europe.
Thanks. More are coming in this style. They are much faster to make than my main channel videos!
More navigation tutorials would be very welcome. Thanks.
More to come!
@@CasualNavigationAcademy Thanks
I absolutely love your channel 💙
Excellent. Clear and practical. :-)
Well explained, thank you
great work I loved this style of video
Great video clear and informative, thanks for your great work. Gavin.
Love the channel and have recommended it to many of my friends learning to sail. An easy but interesting idea could be to delve into some MAIB reports and talk through incidents and how they happened.
Nice video, I'm a fan of your tutorials.
I appreciate that!
New format is good,It would be great if you could do a few more like this as currently now doing my Master 200
Great and very informative
The rose compass can also be used as a rose magnifying glass. With a huge rose at the top of the middle.

Excellent video and please provide more useful tutorials 👍
Thanks, will do!
Very helpful, thanks.
Have been waiting for your new video 🙌
I am so interested in this information. THANK YOU FOR THE VIDEO :)
any suggestions for youth?
Thanks for the video
Awesome 👍🏻
Very usefull, thank you
very good! could you explain a little bit more how the navigation is done?
Do people interpolate the variations if they're between two compass roses will sufficiently different variations? (eg if they're halfway between a compass rose with -30'/yr and a compass rose with no variation, they'd use -15'/yr)
I am a highschool student and when we used cards they tought us if its Increse that we need to add to the East becouse East is plus, or maybe I understood them wrong but your video helped me alot thanks!
Well done
Thanks
Now a days new modern technology being used therefore making videos on ecdis radar will work more please make some detail video about this topic if possible.. your content are awesome like your video very much.
Very Good Sir pls make a video on wind rose of routeing chart much appreciated🤗
Good evening could you make this video with the variation and diviation card.
I am curious, what is the benefit of having the compass rose printed on to the map vs just having an actual protractor beyond that you might drop/lose the protractor?
It is important to have printed on the map for range/bearing calculations and for planning routes. Eg. Looking at the chart, you might decide that you need to go 120 degrees for 1 nautical mile and then 155 degrees for another mile to get around an obstacle. You would use your physical compas to determine what your heading was, but you couldn't use it to guess what your heading should be if you can't see the hazzard. In addition, some charts do not have reliable georeferencing so a chart update might be given with a range and bearing instead of coordinates. You would need a parallel or rolling rule plus the compass rose to update your chart in that case.
@@baileywright1656 You are thinking of direction/magnetic compass. I was meaning a protractor, which in the northwest UK is also called a compass. Completely slipped my mind that this might not be widely understood :D.
Though considering the potential confusion I think I'll just edit the OP.
@@jimmydesouza4375 Ahh, that makes sense! I just learned something new, thanks! For a while, we were actually toying with the idea of taking them off the back-up charts and replacing it with one you can cut out and move around if you needed it, but we managed to get the software to auto generate them anyways so we put a pin in that idea. Basically the same as your protractor idea, though yes, I can see them getting lost fairly easily.
What the cream rose? Because it can become a compass or magnifying glass depending on which way the game goes.
Sir please tell that There is any criteria that how many campass Rose on a perticular chart?
I have a question. Can this method be used for navigating planes as well?
I'm not sure about aeronautical charts.
Like the new video easy to follow ware dose GPS come in true or different
GPS is always "over ground". true headings, speed over ground, course over ground.
As Joseph said, GPS gives position over ground so everything is effectively true.
My cadet days, using this every watch for gyro and compass errors.
I didn't understand very Wellington. I need a step back an a real magnetic compass to make it clear.
Flat-earthers say that proves the Earth is flat.
Thank you so much sir, as always clear explanation and truly useful youtube channel 👍🏼 ⛴🙏🏼
