Grand Prix - Tidal Database
Seatrack’s Tides function provides both information on tidal streams derived from data bases and a comparison (within the system) of course and speed over ground (from GPS) with heading and boat speed (from the yacht’s instruments).
Tidal flows are shown on the chart as at present time or at any selected time over the next 30 days. There is an option enabling changes in tidal flows to be viewed in animated form.
