Reference section 8 — Alarms and TideTrack

Northstar 6000i
TideTrack
™
The 6000i calculates tide information for
any of over 3,540 NOS/NOAA tide stations.
To display this information, press the
STAR
key until you see the
tide track
screen.
The entire U.S. coastline — including Alaska
and Hawaii — is covered, plus many Carib-
bean islands and eastern and western
Canada. Tides can be displayed for any
date up to the year 2010. Data is from the
official tide-table predictions and should be
about as accurate as the printed tables. For
more information about tides, see
Tide
Tables published by the NOS/NOAA, Rock-
ville, Maryland 20852.
The TideTrack screen
The name of the selected NOAA tide
station and the selected day are shown at
the top of the screen.
A graph of the water height for the
selected tide station during any 24-hour
period is displayed.
Press the cursor pad up or down to move a
horizontal measurement line to any spot
on the tide graph. The line is labelled with
the exact height that it represents.
Maximum and minimum heights are
shown as dashed horizontal lines labeled
with the height in feet. Mean Lower Low
Water (MLLW) is shown as a solid line near
the bottom of the graph. A solid vertical
line and arrow points to the tide level at
the current time.
Just below the tide graph is the time scale,
showing the vessel’s local time (LCL) for
each point, and (if the station is in a
different time zone) the time at the tide
station (TID).
At the bottom of the screen, the times of
the day’s high and low tides are listed for
that location, along with the tide height at
the present time.
