Bugger! mispoke/typed, in the set-up. At 11:15 I make the point it is applied to magnetic but I'm afraid I inadvertently referred to True instead of Magnetic earlier. Well spotted! The methodology for the application of Var and dev is correct but I misdefined the course as True, not Magnetic when speaking. In fact, this is one of my earlier videos and I think I could now do a much better, more concise video. Thank you for commenting. I feel a revised and more succinct video is in order!
@@FreeSailingTutorials i didnt get it quite right. If i look at my Compass Heading - it shows let's say 270 degrees, do i need to come to deviation chart with my Compass Heading values and later apply them to what i observe on the Standard Compass on my ship? Or should i imagine Magnetic Hdg values right next to the Cmpass Hdg values with already applied deviation(example: Comp Hdg: 000 -> Dev: 1.0E -> Mag. Hdg: 001 and so on for each value of Comp Hdg) ???
@@FreeSailingTutorials yeah I get it, but if we go from true to compass? Our deviation chart is made for compass headings, not magnetic headings, or we get neglect this and use it both ways?
@@smith1760 Correct, so go to the compass heading and apply the appropriate deviation to get magnetic. Then, go to the chart and establish the variation for the area you are sailing in and apply the variation to the magnetic heading to get True. Deviation relates to the magnetic fields around your boat - variation relates to magnetic fields in the area you are sailing. Hope that answers your question. 👍
Watching this in early 2024, its hard to believe what we went through during the pandemic. I was fortunate to avoid getting ill, but as a member of staff in one of the emergency services, I couldn't stay at home. I have taken early retirement due to ill health and thus have time to do Day Skipper Theory. I am doing it over three weekends with a week or two in between each Sat/Sun full days. Watching TH-cam is helping me learn some of the details which I struggled with on homework exercises. You explain things very well.
Hi there, watching this from Canada (47º 27' 47" N 52º 42' 23" W to be precise!) and at 2:35 in your video there's some type of mark I don't know that has 'Air Canada (Mar - Dec) next to it...what is that? Enjoying your videos BTW, most helpful for the Day Skipper course I'm doing. Cheers.
Hi David. The Air Canada mark is a special mark (yellow mark with yellow x on top). They are usually seasonal and laid on contour lines. They are normally laid for the summer and in the Solent they are used as race marks and are, therefore, regularly sponsored. Hope that helps. Good luck with your Day Skipper!
@@FreeSailingTutorials Sponsored special marks, who knew?! And thanks, I'm finding your videos really helpful, especially the Nav ones, am much obliged. Looking forward to some time on the water!
Error East Compass Least Error West Compass Best (Biggest, Most) I only commit the first of these to memory and reverse it if need be and I just remember the order of variation/deviation without the need for the help of virgins or cadets.

Aren't we supposed to take the deviation from the table considering the magnetic course not the true one?

@@smith1760 When moving from compass to True you first apply deviation, to get to Magnetic. Then apply variation to get to True.

Thank you. Yes. It was a wild wild time. Good luck with your sailing ⛵
Your a really good teacher. Thanks for all your videos, im really enjoying them
Hey Mark. Thanks for your videos. I'm currently prepping for my YM Offshore and they are very helpful.
Thanks Len. Do check out our website too. www.freesailingtutorials.com
Many thanks

So good sir

But that's no fun!
