Years ago, I spent a weekend of a friend's relative's yacht. Tucked behind the chart table, I found a rather useful ready-reckoner type device for approximate HW times around the U.K. coast. You entered the time of HW Dover for the current day (obtained from a Dover tide table) by turning a disc which was superimposed upon a 24 hour clock face. Marked up around the circumference of this "Dover" disc were harbours from the U.K. coast, placed according to their tidal difference with Dover. You could then read off against the clock face, the approximate time of the tide for the harbour you were interested in. Ideal for someone who tours our coast and does not want to buy a new Almanac yearly.
Does anyone know if and where I might buy such an item ?

Or...

If you can't find one, any past year's Almanac will do. They give tide time diff on Dover, so all you need are this year's Dover tables. If you're bored one wet winter afternoon, you could go through the old almanac and make up an alphabetical list of primary and secondary ports with Dover differences, and noting MHWS, MHWN, MLWS & MLWN. If you're clever with spreadsheets you could probably even get it to calculate times and heights for a port, just by entering the Dover info for that day.

Yes they still exist, they were previewed in Februarys issue of DIVE magazine.
They are called QuickTide and are £7.99 each and three tables cover the entire uk's coast line (phone 0117 973 6688). These ones sound a bit more flashy than the old ones with corrosponding table,wheel and colour coded map it will then tell you the HW and LW of the particular area that you are intrested in as well as rise and fall as well as informing you of springs and extra high springs and will cover two years of tides.
For all those who brought me up on my inability to spell apolgies for bad spelling and grammer but I cant find a spell checker on this site!!

I currently use "last years Almanac" and current Dover tables but thought going mechanised might be less prone to human error. As for using spreadsheets, ect I see that you dont know that my middle initial is "L" ...................for Luddite. I am an ex BSAC diver and still have friends who are current members. I will see if I can get a look in Diver at the product mentioned, thanks

I went in on the site and found the test results for your info:-

Product: Easy to use tide tables
Review Group: Other
Price: 7.99
Manufacturer / Distributer: QuickTide

With traditional tide tables you are required to add an hour for BST, subtract the requisite time for coastal displacement and convert from a 24-hour clock. Otherwise it’s a matter of buying specific tide tables for each port. QuickTide, however, provides an alternative. It consists of a table, wheel and colour-coded map of the coastline. How does it work? You select a date from the table, which gives you a code.
You now simply turn to the wheel and line up the code with the corresponding colour of the particular bit of coast you want to dive. The inner part of the wheel now displays the times of both high and low water. QuickTide also gives you guidance to the rise and fall times of the tide. I’ve been using the previous version of QuickTide for the past two years and have found it invaluable and easy to use. What I particularly like is that you can very quickly move around the coast to get slack water times for alternative dive sites, should the weather turn against you.

The new version has light shading on the table to inform you of spring tides, and dark shading for extra-high spring tides. A set of three tables covers the entire coastline of Britain, or each table can be bought individually. They cover two years of tides
Value verdict: 9 out of 10
Performance verdict: 9 out of 10
Invaluable reference tables

Hope this helps

I have just had a look on quicktide's web page and working from an exploded view of the tide finder, I see that areas of coast contained within the same colour band can have up to 90mins difference in HW times.It would appear from the photos that the tide finder would give them the same approximate times of tide. This is a little too approximate for sailing use and perhaps more suitable to other forms of watersports. So, the search is still on

hi there
all you need is garmins blue chart software,, has all charts and tidal entries for loads of places, all over the uk europe.. get the tide anywhere at the click of a mouse!

cool or what...

i have it and its great.... you can also load down all the charts to your handheld as well... or just hook up the gps to the laptop runnning bluechart and you got a color plotter.. as a fraction of the cost!!

<hr width=100% size=1>
 
GPS + most commercial charting software

MOst do tidal stuff in fact you can have currents as well .... but that doesn't answer this guys post ....

The problem with Tide Plotters are that they must approximate many factors and even printed tide tables can be significantly adrift ---- excuse the pun !! due to barometric pressure, solar / space anomalies etc. etc.
Taking various Tidal PC programs that all purport to use Admiralty Data - they all differ !!! in fact sometimes up to 30 - 40 mins. The plotter will average out and be at best only a help in determining approximate tide times.

At the end of the day - as most , and I know that many will not agree - despite the fact that they probably do it as well ....- we use tide tables as general data and not exact, moving / approaching channels and sand bars etc. with time to spare etc. The only time we really calculate it to the n'th is for exams / licence courses .....
