Thanks Chuck (and all you others) but does anyone have the magic number
I need to plug into my new Casio watch to help me figure out the best
time to go to the harbour?
As there is a delay due to the restrictive inlet into the harbour I've
got a feeling this is not going to be possible.

Start of course with the Admiralty tide tables.

As with everywhere else on the planet, it takes 18 years and 6 months
to complete an entire "tide cycle." Tides at Poole Harbour are
generally semi-diurnal, with two highs and two lows per day. The lunar
day is 24 hours, 50 minutes, so if Poole is not influenced by
topography (I suspect that it almost certainly is) there would be a 12
hour and 25 minute interval between one high tide and the next.

Some additional general information:
