Every day the moon circles the earth twice. The gravitational pull
causes the tides to be high and low twice a day. The moon is in a
concentric circle around the earth and completes this path once a
month. This causes neep and flood tides in rythem with the moons path.
Just look at the moons cycle and you will know what the tide will be.
or you can buy and eldrege book and just look them up.

BOATING magazine did an extensive article on how to do just that
for your specific crusing area(s)...don't recall exactly which issue,
but certainly w/in the last three.

Hi Mitchell,
I have a computor program on my MAC that will plot any point that
is in the NOAA book. If you send me VMS mail I could plot yopu
out some specfic dates.

>> In order to calculate your own tidetable.
A computer program is just what you want. Last year I took an advanced
navagation course and the chapter on tides & currents was the longest
of 'em all. The 'formula' for calculating the Height of the water
at a particular Time, for a given Area requires a table for the
general area of interest, indicating the Times & Heights of the
high and low waters. In addition, you require a table of Subordinate
Stations which indicates time & height "differences" for
a specific area(s) of interest. This data is used in conjunction
with the tidal info for the general area (addition/subtraction of
differences) to yield the time & heights of water for the area
you're interested in. Why anyone would want to have to think about all
this in addition to everything one thinks about while piloting a
boat is beyond me. As a previous noter said....subscribe to the
NOAA publication.

| Thanks MArk, the subscription is easier and faster than
using the computer. Not to mention the cost of the program.
