14 - Tides & Currents
Tides & Currents is a stand-alone application that provides tide and current
prediction data to Jeppesen Workboat Navigator. Tide and current predictions can
be overlaid on top of your charts or used independently to create detailed reports
and research tide and current information for all the NOAA and CHS primary and
secondary stations in the US and Canada.
Tide Bars and Current Arrows
A Tide Bar, or tidal station, is shown on the chart as a red and white bar with a
blue field on the right side. Current Arrows, or current station, is shown as a red,
transparent arrow.
To display tide bars on top of your charts, click Context Menu | Layers | Tides
from an open Chart window pane.
To display current arrows, click Context Menu | Layers | Currents.
After activating tide bars and current arrows, you should see tide bar and current
arrow icons (as shown in Figure 14.1) on the chart. If you do not, there may be no
tidal or current stations in the area currently displayed within the chart window pane.
If this is the case, zoom out until you are able to see tidal stations and current
arrows displayed in the chart window pane.

Interpreting Tide Bars
The tide bar icons on the chart display a quick indication of tide height based on the
present system time on your PC. The blue section of the bar indicates tide height.
The more blue visible, the higher tide height will be.
Right-click on a tidal station and select Properties from the pop-up menu to view
information about that station using the SysInfo | Tides & Currents panel. Or, if you
have the Display Screen Tips on Charts option turned on, you can hover the cursor
over any station to see the name of that station and its associated height value.
The Display Screen Tips on Charts option is set to Yes by default when the
program is installed. This setting can be turned on or off using System Menu |
Tools/Settings | Options | Misc.
