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?

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.

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.
