Plotting on a nautical
One note, using the compass rose you can either use the compass setting or the true-north setting. When using the meridian they will have their course for true north and may forget to correct for variation for a magnetic heading. I use my aviation plotter for both nautical and aviation since it's so easy to use it on latitude and longitude. I like your presentation very much.
Another excellent video. Maybe I am a geek, but I get excited every time one of your videos pops up in my notifications.
I love your video!! Just subbed. Check out followsm[.]com! It would be the best way for you to reach more viewers!!!
I never knew about the sandpaper trick until today.
Also, I agree that a few pin pricks in the map is a fair price to pay for an accurate measure. I come from aviation, where it's mandatory to replace maps every year: I always did my routes in pen. I did my daily math and notes in soft pencil of course, but my primary track line and my 10° lay lines and any hazards on my route were marked in pen because I'm always going to fly the same routes, so why not: after a year of drawing and erasing pencil lines in exactly the same place every week (small airline, same runs, same altitude, every week) the other pilots maps were barely readable while mine could have been used another year easy! Man did this bother some of the captains though! I can't imagine doing different for sailing since I want to permanently keep a souvenir of my journeys; I do understand it would of course be different for tugs, fishing boats, etc, that wander around more, so depending on the circumstances one has to use some judgement, but there's no need to be a religious zeolite about it! My mom's Bible is marked up with notes all over, and that's how I treat my charts: if I notice a tall tower or a shallow reef I circle it, in pen: just because I noticed it today does not mean I'll notice it when I'm tired some day.

At the 8:30 mark you use the second triangle to move the first triangle away from the plotted course to get to the meridian. Might it have been more accurate to hold the second triangle on the plotted course and then slide the first triangle until it's converging lines meet on a meridian. This would allow you to visually check that the first triangle is both directly on the plot line and the converging points line up at the meridian. You could only do it this way if your course is at least somewhat off of due North or south.
Your voice is so soothing.
Very clear explanation. :) Thank-you.
Barabing baraboom.
You are awesome, Sir!
Soils is a super important
A very informative straightforward lesson sir..You helped me a lot as today is my bio practical...
But how how do you know when to draw the line horizontally and when to draw the line diagonally? (coming from an environmental science class hehe)
Thanks!
THANKS YOU
Hi, so if it’s between 2, can we write both or any? Will it be correct?
You don't use a Portland Plotter at all? Quick and easy! https://youtu.be/1gYeR10549k
Excellent tips, thanks for sharing.
Regarding reading Courses and Bearings, are you a fan of the Breton style plotter?

Or simple you can use a Portland plotter to set the course and make declination adjustment as well.
How do you plot on a harbor chart? The scales have me off, is there a conversation I have to do?
