Explaining the interpolation for Secondary Port Tide Calculation

Since one of my subscribers pointed out that the interpolation process was not very clear on my previous video, this video explains the interpolation involved in the calculation of secondary port tide calculation.

I was literally disappointed in class today for not understanding of this calculation but now i'm over the moon, Thank you soooooooooooooooo much sir, well explained and well understood. love u sir...

[@prakashsingh6801]

I was confused with my own notes and now saw this video and loved the way of explanation and now I am clear with my questions
Thank you very much.

Hi
For preparation of second mate / DNS/ BSC nautical science/NCV come in #kundanpatna

[@waelsailor5414]

Your videos saved me sir, it cleared many ambiguous points to me and illustrated a lot of important explanations, so thank you
However , some tide videos have a problem with their audio, it is intermittent in some of their parts, but not in all of it.

[@jonesmiranda4071]

Good explanation.. cleared my doubts thank you

[@dipakdiwakar8232]

Thank u sir before I had doubt in interpolation part now I understood that thank u sir

Great 👍

Great, thanks heaps! 👍

How do we interpolate between the pecked curve and the solid curve , when using the Mean Spring & Neap curves attached with the daily tables of the standard ports?!

[@hanifmallik4704]

For low water sir after interpolation it's coming -.12......u too has positive sign ...how can u please explain bcoz -.3*.3/.7

[@waelsailor5414]

How could we use the (Mean Spring & Neap Curves) , the solid and pecked curves, attached to the daily tables of the standard ports, for finding the time of given height of water, or the height of given time, in a standard port and in a secondary port. ?!

[@waelsailor5414]

I noticed that sometimes a (time difference interpolation) is needed,
Would you kindly illustrate how to solve that?!
Thank you very much.

[@aj_mariner8323]

Sir there is one doubt.. If in question nothing is mentioned about the method if solving tide i.e Shm or graph. Please tell how to find out for secondary port

Thank You Sir 🙏
Can we do extrapolation by calculator?

[@mayankseth1298]

Sir please solve 1 or 2 questions on vessel aground in tide

[@VivekSingh-ic8kz]

There is formula
Height of tide = L.W+(factor×range)
Hot calculate factor
Plz help me

thankyou so much sir, but i hve qstion is mhws and mhhwl same?

[@sharvanipaul7536]

Super! Thank you!

[@markjoonedyramirez9665]

sir what about if the value of seasonal change is negative (-1) how i will reverse sign substract algebraically?? it will be reverse to positive(+) pls answer pls

[@SteeringMariners]

Hi Mark, the procedure remains same whether its a positive or negative value:)

[@markjoonedyramirez9665]

@@SteeringMariners sir if the seasonal change is negative. i will reverse it to positive and i will add?? is that correct sir??

[@SteeringMariners]

@@markjoonedyramirez9665 correct 😊 so kind of u...I appreciate it buddy

[@shubhendusingh2071]

Sir, is it since at Enewatak Atoll we only had one value for HW & LW time difference so we didn't interpolated, whereas in secondary ports such as Drummore(420) we need to interpolate for time difference aswell?

[@SteeringMariners]

No Shubhendu, you will not interpolate. Just apply the different pertaining to the time it is given. For example, if there are 2 HW time differences give, the upper one will be for the upper HW time and the lower time will be applied to the lower HW time.

Thank you Sir for your prompt reply 🙏

[@MsTeus13]

Not so clear in terms of the Interpolation.
