Ep 30: Navigation: The Nautical Chart 

Thank you Sail Ho

Thanks Tom. I think you're onto something. Reading all the comments in the various FB groups I've posted to has me thinking the same way. I think a lot of people are intimidated by learning manual navigation. Hopefully I can produce short easy to learn vids that will get past that.

@@CarpeDiemSailingMagazine , short and easy is key. Break it down into small chunks that people can easily watch. You’ll lose people if they’re long, complex videos. Look forward to seeing what you produce!

@@tomtiernan8134 Absolutely Tom. I have the attention span of a five year old so short and engaged is the way to go for me.

@@CarpeDiemSailingMagazine , same here.

My pleasure! Thank you for the kind comment SV

Thanks Richard. Delighted to hear it. Don’t hesitate to reach out if i can be of s as my further assistance. Good luck with your training 👍

Thank you for the comment.

Thank you for the kind and supportive comment.

Thanks for sharing!

Glad you enjoyed it Thank you Rimas 🙏

Yes, you can get CHS charts. Actually they are my preferred chart. I have a package entitled CHS RM-PAC02 Vancouver Island East. Depending on the package they run from $49 =- $149 buy they dont seem to expire. I've had them for a few years and my Navionix charts are expired.

Thanks for the comment Mark. Could you please clarify. I’m not familiar with a nautical chart making such a statement. Further, tides don’t ebb. It’s a bit of a misnomer. As you stated correctly the tide is high or low. Ebbing and flooding is relevant to tidal streams, that is, the horizontal flow of water driven by the tide rising and falling. Finally, for me I would interpret the “shoreline” at low tide. On Canadian charts the shoreline is marked at chart datum which is Lowest Normal Tide. Hope this answers your question

Thank you 🙏

I’m not sure. This is a question for one of my navy navigation officer friends. I’ll get back to you.

This is the reply I got from my navigation officer friend: "The short answer is yes. For long trips that have a northerly or southerly direction, and all trips close to the equator, there is very little difference between a great circle and a rhumb line, the latter is a straight line on a mercator projection. For a trip that is easterly or westerly and away from the equator, you would have to break up a great circle into rhumb line segments. There is planning software that can do this for you. You simply input the departure and destination lat/long and how many segments you desire. We typically break a journey into segments of 10° of long, as the greatest the distance can be is 600nm, which is about where there starts being a noticeable difference in distance between GC & RL. I hope that makes sense"

@@CarpeDiemSailingMagazine thank you so so much to you and your friend, this is the best most clear answer I got over weeks pondering about it, I am so glad I bought my mercator charts then, planning a passage from Australia to Tahiti. Thank you for your great channel too :)

Thanks, I’ll keep it in mind.

Nope. I travel between between countries, USA, MEXICO AND CANADA so all the info is important.
