Tide Clocks!

[Norman_E]

I found these while trawling E-bay for a replacement clock part.

Only the clock insert is sold, so you need your own case, but they come in two sizes. Now there are no tides where I sail, but for anyone in tidal waters a stand alone tide clock that makes a complete turn of a single hand every 24 hours and 50 minutes looks like a great idea.

I'm also non-tidal but presumably the tidal clock is only correct if you stay in one port? As soon as you sail anywhere you have to alter the clock.

You set it for your home port or an appropriate base port & then use a differnce table for destinations & tide gates. So I can set mine at home for Caernarfon so I know when to arrive so that I can enter & leave promptly.

If I had one on the boat it would be set to Liverpool so I could use the difference table in the front of my tide tables (which I could copy to A4 & laminate) to know the current state at any local pinch point, overfalls & harbour.

The thing I liked about those clocks, that I had not seen before, is that they are just a tide clock, with no time hands to confuse you.

I got one for Christmas from www.tideclox.com. They have a very wide range and its a nice thing to have at home.

I have two, different makes, one for the kitchen and one for the boat. They tell both time and tide, four hands in total, hour,min,second and tide.

I have a "cheapo" travelling alarm clock whick I have fitted with a home made face depicting HW LW and associated hours in between . Removed the minute hand but kept the hour and alarm hands. Although only usable for 12hrs at a time its accurate and has a useful alarm .

 

[Norman_E]

Nobody seems to have spotted my mistake. The single "hour" hand makes a complete turn in 12 hours 25 minutes, not 24 hours 50 minutes. Effectively it shows from one high tide to the next, so works for everywhere though less useful in places with crazy double tides, like the Solent.

I think you got your words muddled up?

It should read:

" . . . less useful in crazy places with all those armchairs floating around on double tides in the Solent!"

I found [URL="http://www.ebay.co.uk/itm/150mm-TIDE-ONLY-QUARTZ-CLOCK-INSERT-MOVEMENT-

I have seen these movements online for as little £6.00 + £2.50 online and I dare say they come in from China for a couple of quid if you buy a sack load,would make a fun Blue Peter project use your favourite photo in frame and a homemade dial and no need for a toilet roll tube.

Their movements are much cheaper than the eBay ones, looks like a good project to convert a redundant clock face.
