Calculating Secondary Port Tide Times and Heights

I calculate tide times and heights for the fictional secondary port named Edenfield.
Edenfield's standard port is Hamilton Sound. So I need to use the tidal information and curve for Hamilton sound, but calculate the differences for Edenfield first and then I can use the HW time, height and LW height on the Hamilton Sound tidal curve.
0:00 Describe problem scenario
1:24 Get tide times and heights from Almanac
1:50 Note particular HW and LW times and heights for date
2:25 Show Secondary Port differences from Almanac
2:45 Draw scale for Standard and Secondary port HW time differences
3:45 Calculate Secondary port HW time
3:53 Draw scale and calculate HW Height for Secondary port
5:48 Create Tidal Curve using HW Time and Height and LW height
7:18 Convert UTC-1 to local time
7:58 Calculate a second example for another day
8:45 Work out HW Time difference
9:07 Work out HW Height difference
9:22 Work out LW Height difference
9:27 Mark up Tidal curve using calculated data

The best video I’ve found so far regarding secondary ports. Very clear and simple and good to learn a method that isn’t ‘crocodile jaw’

[@Leo-td4tj]

been looking for the manual calculation one cuz i need to present it but man it's so confusing.. maybe i'll just present this method instead

[@uglybaba1]

you made the interpolation very easy.So far the best method I've ever come across.Thanks a bunch !!

[@Leo-td4tj]

Sir do you also need to take into account the seasonal changes?

[@sbcode]

No, I'm using the tide height values straight from the almanac for the particular date and time I'll be there.

[@Leo-td4tj]

@@sbcode thank you sir😁

[@uglybaba1]

@@sbcode Could you please explain this in more detail as why the seasonal correction is not required.Can we use the same method for Pacific tides as well.Thanks

[@sbcode]

The values from the almanac are seasonally corrected already. For Pacific almanacs you need to check with the publisher

[@julianbrose9097]

low water was at 1613 not 1413

[@sbcode]

Well spotted. You are correct.
