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!

thanks so much for the great comments. I too am biased I guess, Kirsten has had a few great days and is looking good, even after the rescue

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.

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?

@searchingforcoconuts2248 Жыл бұрын

Hi, first, thanks for watching and contributing. Slack tide could be high tide or low tide, refers to the exact time of the high or low tide, where less water movement can be expected. Not necessarily the best time to sail, but definitely the best time to go through any kind of channel or in confined areas. In areas where tidal range is very high, the amount of water could be important. For us and where we sail, it's just important to know that around 3 hours after or before the last slack tide, is when we will experience the most water movement.

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

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.

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

@searchingforcoconuts2248 2 ай бұрын

HI, and thanks for posting... In this example, we worked out the tidal range from first low to first high which is 0.7m to 1.56m, giving us a tidal change of 0.86m... if we wanted to work out the next tidal range, as you have suggested, then you are correct, it would be 0.98m. Hope this helps
