Real Tide
TIDE DATA FOR SHIP SAILING IN NORWEGIAN WATER
Tide is calculated in real time under the ship’s position and tide data displayed in the Drift
panel in the console area.

REAL TIDE
The real tide function allows to get precise tidal prediction in each zone of the Norwegian sea;
Press T key inside the yellow surrounded area to get Real Tide sea level for this tide zone.
Real tide is based on:
• astronomical tide,
• real time tide observation,
• weather forecast.
The 3 series of data are computed to give the more precise tide prediction in Norwegian
waters.
(Option available with “Pilot” installation only).
Only Astronomical tide is displayed when no data downloaded.
Press button to get data from Norwegian HO server and get the status.
Real tide is computed from Astronomical prediction and loaded data (example).
The difference between Astronomical and Real tide can be more than 1 meter and be really
usefull for many areas.
Observations are updated on server each hour.
24 hours of historical data are downloaded back and 36 hours prediction are downloaded.
Therefore Meteo prediction is available for -24 h ... + 36 hours.
All this data is saved on HD and will be restored later after access to the function.

This module should be installed and requires licence key and activation key.
Different kind of ports are defined:
__ Standard Ports - These are ports where the tidal predictions are calculated from a set of
harmonic constants
__ Secondary Ports – same as Standard port, however the observations made to collect this
information generally were not as extensive as with standard ports and so the tidal
predictions are of secondary quality.
