68 RayTech RNS V6.2 - User’s Guide
9.2 Tides
Tide height data - see page 62 - is a prediction for maximum and minimum
tide heights over a 24 hour period for a selected station in a selected
region.Data for sunrise and sunset is also provided.
As long as you have a valid global positioning system (GPS) time /date
signal being received by RayTech, the graph will automatically default to
showing today’s tides. If there is no signal then the graph will default to an
earlier date.
Some regions have non-sinusoidal tide patterns, with distorted or multiple
high and low water peaks and troughs. In such regions, it is better to refer
to the graph to determine high and low water times and heights rather
than using the textual description above the graph.
