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?

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?

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.

"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.

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.
