Total Tide
__ Secondary Ports (non-harmonic) - These ports do not have any harmonic constants,
instead their tidal predictions are calculated by taking the prediction for a reference port and
applying time and height differences.
Main tide stations are represented by a red square icon, and secondary stations by a yellow
one. In this case, click the link to open the main station window.
U Custom Ports - These ports are ones that are defined by the user by manual input of a set
of harmonic constants.
The chart date is displayed in local time. It can be adjusted in the time setting dialogue or
synchronise with ECDIS time using the button Time Synchronisation located in the weather
panel.
