tide clock
From sailing to sand castles, everyone needs to know what the tide is
doing! Synchronised to the moons daily cycle, the ashortwalk tide clock gives you an innovative and convenient guide to tides. Simply set the hand to the high tide position at exactly high tide for your chosen location, then throw away your tide table! How does it work? Tides are caused mainly by the moons gravitational pull on the ocean. The time it takes for the moon to reappear in the same place in the sky each day is 24 hours and 50 mins. Most areas in the world have two high tides and two low tides a day, so the tide clock has been designed to rotate every 12 hours and 25 mins.

I use my sailboat in tidal water and reversing falls. I love to install a
Tide Clock on my sailboat. However, I am apprehensive as it might mislead people looking at the tide clock. Mainly because, after inquiring about these clocks, I have learned that they are not to be used for navigational purpose. More so not to rely on these clocks fro tide information if there is a chance for damage, loss or injury resulting from improper tide information. Until I am sure I will still use a tide table and GPS programs. The problems appear to be causes by land configuration compounded with current speed. The Bay of Fundy is like a funnel while the Gulf of Maine has a different configuration. On the West coast they have some phenomenon that I cannot explain which make the tide clock more unreliable? What do you think? "stljlj" wrote in message oups.com... From sailing to sand castles, everyone needs to know what the tide is doing!

Tides aren't as big a deal in my sailing area (Halifax/St, Margaret's Bay/Mahone Bay). I was given a tide clock by my union executive when I retired and it'd proudly displayed as soon as you enter into my front hallway. I use it to guage launching time for my trailer sailer. |

The slack time for the Reversing Falls is calculated using the tide Canadian
Tide and Current tables. On average the calculated slack time has a precision of + or - 5 minutes. After heavy rain fall or dry spell this precision of + or = 5 minutes will vary. That when local knowledge comes into play. At time, I have seen a variation of 10 to 15 minutes. Going to Tiverton passage, entering Digby gut only to name a few your calculations have to be right on or you may have to wait for the next tide. Other river mouths are known to pull you in quickly and then dry out as fast. That does not mean that I will not have a tide clock on board. Last week I saw a few at the Binnacle and they are very attractive. At this time, I do not trust this clock for navigation but if after a while I can develop a confidence in them I may get a warmer feeling. "Jeff" wrote in message . .. Are you saying that the clock is unreliable, or that the tides are unreliable? And if you used a tide table, what clock do you use to know what time it is? Actually, if I were going through the reversing falls in St. John I would be synchronizing my clocks with GPS time and consulting the tables. Of course they do have traffic lights to help you. I would be curious as to how constant the tides are there - how closely do they follow the lunar cycles? And are they greatly affected by weather conditions? * wrote, On 5/20/2007 6:55 AM: I use my sailboat in tidal water and reversing falls. I love to install a Tide Clock on my sailboat.

"Of course they do have traffic lights to help you." You're jocking. No there are no traffic light to helps. In some countries when you use canals you may see signal lights controlling access to locks but not in the reversing falls. * wrote, On 5/20/2007 6:55 AM: I use my sailboat in tidal water and reversing falls.

Sorry, I thought I remembered something about lights as you approach the falls that indicate slack tide. But of course I can't find anything about that now, and all my guide books are on the boat. The idea of having a signal light to indicate the slack time is a good one. The reason for not having signal lights may have to do with liability. I have a few pictures showing sailboats waiting for the slack time. If you want I can send them to you. |
