and selecting a station.
Route Calculator
The Route Calculator uses current predictions to calculate best departure times,
transit times and required speed. You can use this information to calculate how long
the trip will take. In order for the Route Calculator to work, current stations must be
attached to the route legs in a created route.
By default, Jeppesen Workboat Navigator will automatically attach the nearest
current station to each route leg. Because this is done automatically using the
nearest stations, there may be other nearby stations that will have a stronger effect
on your trip and on your arrival time calculations. In this instance, you may want to
manually attach a station to a route leg.
To Attach a Current Station to a Route
Turn on Current display by placing focus on the chart and selecting Context
Menu | Layers | Currents or by right-clicking on the chart and selecting Layers
| Currents from the pop-up menu.
Click on the current station that you want to attach to the route leg.
Drag and drop that station onto the closest route leg.
A dotted line (see Figure 14.4) should appear between the current station and
the route leg.
Repeat as necessary for other legs of the route.
