The velocity scale at the top left side of the graph changes dynamically 

based upon the maximum velocity of the current for that day. 
Slack water, the period of little or no current, is represented by the 

Slack Water Line (SWL). The flood appears above the SWL and the ebb 

appears below the SWL. You can look up tidal current data for other 

dates by changing the month, day and year selection boxes.  
To select another date: 
1. Use 

← → to highlight month, day or year, then press

2. Use 

↑  ↓ to select the desired month, day or year and press

Tide Information 
NauticPath charts contain Tidal Information, repre-

sented at large zoom ranges by a box icon with the 

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

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

mile), the icon becomes an animated gauge showing a rising or falling 
tidal height for the selected station at the present time. At larger zoom 

ranges, you can select the boxed "T" icon and it becomes an animated 
gauge with a pop-up name box. The name box disappears seconds.
