Tides is a very easy-to-use tide/current prediction program.Tides predicts tides and currents using a large database of US and worldwide locations. It graphs its predictions and even animates them. In comparison tests, Tides' predictions are in good to excellent agreement with a sampling of published and on-line tide tables.Tides is an MDI (Multi-Document Interface) application -- this means many locations can be graphed at the same time. You may print prediction charts, copy a graphic image, or create application-portable databases of any size.
