Allows you to predict tides and currents for about 9,000 locations around the world through the year 2038. Tides are depicted in various graphical forms with daily and monthly textual charts selectable via a menu. Sun and moon rise, set times, and lunar phases are also computed. While all functions are interactively controlled, unattended processing is also supported for automated output. In addition, the monthly calendar function presents the tides (or currents) for an entire month starting at any date in the database.
