Hi Everyone, I made some changes to my channel this winter that resulted in YT deleting all of my comments/replies on these videos. It's really a shame, because I feel like I have answered quite a few theory questions in the comments section over the years. If you have a question, even if it looks like it's been asked before, please don't hesitate to post a comment, I'll do my best to get back to you. Cheers, JH
Thank you for taking the time and effort to put together all your invaluable teaching tutorials. This is what RUclips is best for. Really truly appreciate teachers like yourself.
Fantastic explanation of vectors and I have found all your videos very clear and concise. Just one issue here. Nautical miles should be read off the parallels of latitude scale (vertical scale) and never meridians of longitude (horizontal scale) when using a chart. Meridians of longitude converge towards the poles as you travel from the equator.
You're right, that is an error at 12:45, although there is no scale available on the screen where I could have taken kts from, thank you for pointing this out. This is definitely not a chartwork tutorial, just an illustration of a practical use for vectors in sailing.
Thanks for this, I only just started watching but feel that the series will prove to be a useful addition to my knowledge around sailing. Watching at the first example, I have a question; since you seem to suggest the boat is moving at a higher speed than 3kts (since the resulting vector's length - which is the diagonal of the triangle shaped by the velocity and the current - is longer), so should I assume that the original velocity of 3kts is speed over water (vs. speed over ground)? or am I confusing these?
I agree, it make sense. It was mentioned as a boat speed, that made confusion. Apart from this, your presentation is the far best and very educative! Regards, Boba

I pronounce you Sir as "Best Physics/Math Teacher" on RUclips!!

Is the boat speed vector is in this direction? That should be facing up, and the apparent wind is different as a resultant of these two vectors
