Thank you for your great explanation sir. I have one clarification sir. If I apply my time difference for second low water and if I get a TIME for the next day ( JAN 3 ) , I will look into the previous days Standard port value and get a time and ht value... So will this new ht value from previous day become my first low water ( ie MLWN) ? Thank you in advance sir
Can you please make video on interpolation and calculation of tides calculation of ATT volume 1 diagonal interpolation both of primary major ports and secondary ports, Plz 🙏
Good day, Thanks for writing to us. If you get negative value for a tide it means the tide has fallen below chart datum level which is lowest predicted height of tide from which all tide heights are meassured. This is not often seen but is very well possible, can be observed in ATT also some height of tides are marked negative.
Good day, Thanks for the responce, Factor is the value that you can see at the mid of you graph curve written vertically from bottom to top, these values were used to find the ht of tide without being getting into drawing whole lines through graph up and down, but there was chances of getting much errors in it, the formula u mentioned can also be used to find ht of tide, it is an older method used and not preferably used nowadays, Comment for any further doubts Regards, Team Ahoy!

sir you take wrong value time difference calculation MLWS value is 0.7 and MLWN value is 2.3 but you take MLWS value is 2.3 and MLWN value is 0.7 you see once again your admiralty tide tables but anyway your teaching is good you take only that value is wrong sir you not look properly your admiralty tide tables book you take wrong value for secondary port MHWS AND MLWS value also wrong
Such a great help, thank you dear
Hi friend
For preparation of second mate / DNS/ BSC nautical science/NCV come in #kundanpatna
Nicely explained. There is a mistake though . You intermixed height difference values of MLWN and MLWS
Thanks you very much 🙏

Glad you found it helpful,
For the clarification yes that will be considered as the first time tide of the day
@@SailorSyd007Sir It will be considered as HT aur LT??
Sir what if the value for interpolation is outside the range so we take take extreme value of range or extrapolate
No extrapolation , just take extreme values

Can you do a video explaining harmonic constant method.
Thanks
Good day,
We will look into it.
Thankyou

What if we get final height for secondary port negative?

Hi sir .can u plz send the link of ATT Vol2 and 3 of 1992, the one which u used ..in ur video
bro my humble request please show how to do interpolation one time please bro
Sure stay tuned we will come up with that soon
I have doubt on interpolation what you did here.
Hai bro can I get admiralty pdf copy.....??
There is a formula
Height of tide = L.W +(factor×range)
How to get factor
Good day,
Thanks for the responce,
Factor is the value that you can see at the mid of you graph curve written vertically from bottom to top, these values were used to find the ht of tide without being getting into drawing whole lines through graph up and down, but there was chances of getting much errors in it, the formula u mentioned can also be used to find ht of tide, it is an older method used and not preferably used nowadays,

Yes i admit please understand the concept and proceed with the problems.
