Basic Navigation Part 2 

The animations are really helping visualise. There is nothing new here for me, but I remember how helpful I found your videos about standing rigging and running rigging and where everything goes and how it worked.

The production quality in this series is the best i have seen yet, Great work and thanks so much for the time and effort _o_

Thanks for making this! It's really well explained.

Thank you

Thank you so much for taking the time to make us all smarter sailors. You guys do a great job at teaching.

Thank you !

Brilliant clear explanations and imagery! Thank you.

I like the educational aspect of this channel! The rule of 12ths is nothing to fear! It’s a good way to approximate a sine curve for six equal time increments, which is very close to how tides behave. In fact, it matches a sine curve exactly except at 1/12 (20% error) and 11/12 (2% error). Another way to illustrate the water level change with time is with an analog clock face, where high tide is at 12:00, and low tide is at 6:00, six hours away. As you move around the clock, the vertical rise or fall corresponds to the water level change with time. Example for a falling tide: First hour: From 12 to 1, the vertical drop is small, about 1/12 of the way from 12 to 6, or 7%. After two hours: At 2 the level has dropped 1/4 of the vertical distance (3/12). After three hours: At 3 the level has dropped half-way (6/12) After four hours: At 4 the level has dropped 3/4 of the vertical distance (9/12) After five hours: At 5 the level has dropped by about 11/12 or 93%. I find it easier to remember 1/4, 1/2, and 3/4 at 2, 3, and 4 hours, with the first and last hours being the 1/12 of slack tide. PS, In the figure shown at 13:11 in the video, equal increments of water level are shown rather than water level for equal increments of time.

Wonderfully explained. Merry Chritmas & Haapy New Year

This is great! I'm a new sailor and this makes it all clear, thank you! More please

Absolutely fantastic information ty

This might be the best explanation of the Rule of Twelfths I have seen. My Grandfather tried to teach me this some 45 years ago and 10-year old me just did not get it. Thanks for helping me understand.

Thanks ... appreciate the content very much.

These are such valuable videos, thanks so much. Really clear, terrific graphics, and very methodical. I'm rooting for Kirsten! She bought her boat where I live, Newfoundland, it used to sail out of one of the yacht clubs here, so I'm biased!

Very good videos. Thank you!

Really appreciate your time and help! Thank you!

This is excellent... thank you for making this it's been very clear and concise and helped me a lot

Thanks a lot for for this , it's well explained , first class mate!

Hi. Thank you very much for this clear and informative educational videos. Do you plan to continue the series?

I decided to learn some basics because I just watched "Adrift" movie

Thank

This was was very helpful too! Great education. I listened to this the first time through, and I couldn't understand the barrels but then the 2nd time I watched the video and understood more. So the "slack tide" just means the time in the cycle between low and high tide when there is less fluctuation in the amount of water, therefore it's calmer, correct? And was there a suggestion this is a better time to "set sail"(?) because of this? Was a little fuzzy about that part and the reasoning why. Do you suggest doing this high tide low tide barrel ranging calculation before each time setting sail?

Sir Robin KnoxJohnson officially crossed the finish line first but only because Bernard Montissier decided to forego finishing and just headed back out for a second trip around Sir Robin has gotten all the accolades but Bernard Montissier proved he was the best sailer in the world, at that time

how is tidal range 0.86 1.56 m-0.58 m=0.98 m maths isnt mathing
