Tidal Current Information 
NauticPath charts contain Tidal Current information, 

represented at large zoom ranges by a box icon with 

the letter "C." These icons will appear when you are 
zoomed in to a 6-mile range. The icon stands for a 

Tidal Current Station location. An example is displayed on the right. 
When you zoom in to a sufficiently small zoom range (0.8 nautical 

mile), the icon becomes an animated arrow showing tidal current veloc-
ity and direction for the selected tidal station at the present time.  
At larger zoom ranges, you can select the boxed "C" icon and it becomes 
an animated arrow with a pop-up name box (the name box disappears 

after a few seconds). Examples are displayed in the following figures. 
To view Tidal Current information: 
1. Use the arrow keys to move the cursor over a Tidal Current Station 

icon. When it is selected, a pop-up name box appears. 
2. Press 

 to display the Tidal Current Information screen.
