Seafarer Tides
Seafarer Tides is an official electronic product that is equivalent to the ANTT. It has the benefit of producing a graphical representation of the tidal curve and predictions at 1, 20 30 and 60 minute intervals for each location represented in ANTT. Seafarer Tides is released annually in October and provides tidal predictions for the following calendar year. As required, update patches are available from the “Downloads & Demos” section of the AHS website.

Tides section.

Future
Publications
Other products are being planned include Australian Tidal Stream Atlas. The Tidal Stream Atlas will contain detailed information on the rates and directions of tidal streams in many locations around Australia where these data are of importance to navigation.
