Hi All
This might sound like a strange request but I'm looking for a tide table website that can be interrogated for specific times at different stages of the tide.
In my case I know that if I launch my dinghy before the tide drops below 1.2m then I can step in from shore, and if I launch once it's under 0.7m then I have to walk it through the deepening mud.
If I can find out the times these heights occur it will help make my trips more pleasant.
I guess I could HTFU but it's winter and my feet get cold. 
If I am understanding you right, the data you require is on seabreeze. Have a look at the tide chart and hover over the time you want????
If you really want to be a nerd you can also calculate it yourself by drawing a tide chart based on the data from the high / low tables.
Or you do a tidal reduction by hand and just check you calculation for your secondary port.
Bit old school though.
just a though
your fully automated data for avery day , whole year.
.annual tide table for your location in PDF
.convert to word
. place in excel
. create the formula
. main page / date entry, time available / in Power Point
OK, so being just a bit geeky, I did an excel spreadsheet that takes the time and height of the two extremes of the tide in question.
I then nominate the height I want and it's gives me the time that height occurs.
The tide height is only calculated on the old 1/12, 2/12/ 3/12 system and interpolated to the height required.
Not sure if the 12th's rule will be accurate enough for what I want.
