Using Tides and Currents
Introduction
Tide height and current data is available for many areas on the chart application
of H6.
The predictions displayed for Tides and Currents are sufficiently accurate under
moderate weather conditions, for the coastal areas served by the reference
station, to be used for navigation planning. However, certain weather fronts and
storms can alter tidal patterns and influence predicted times and heights.
In addition and in common with all similar products, tidal data is calculated
algorithmically and may, in some regions, be subject to error. If exact tidal heights
or times are critical to a particular passage, Raymarine recommends that details
are checked against a Tidal Almanac published by the appropriate marine
authority.
Tides
Tide height data is a prediction for maximum and minimum tide heights over a 24
hour period for a selected station. Data for sunrise and sunset is also provided.
When using tidal information the default is always the last selected station. As
long as there is a valid GPS time/date signal being received by H6, the graph will
