I don't mean to be rude or abrasive but if you can do simple mental arithmetic and count to twelve you can work it out in your head.
If you're new to the sea go to the first seaport, moor there for a week, watch and learn the rhythm of the weather and the sea.
What about seaports with diurnal tides? Or worse, mixed, semi-diurnal?
My paper charts are blank on the back....or just another chart, nothing with tides unless you are talking charts of tidal ranges.
Learning rythm in one week doesnt mean the same size tides the next.
And I agree with the OP, why bother with the calculating, when a single click can give it instantly plus a couple clicks more to change dates?
Plus the graphics are going to show the "rhythm" a lot quicker than sitting for days to get a miniscule glimpse of tidal changes.
I am old school in a lot of things...but this is about data more than seamanship....and getting it easy isnt bad.
