Lake Sidney Lanier gps offline chart for boaters

***Seawell launches series of Lakes and Parks on to the market with up-to-date maps along with fishing spots and aerial images. For people who are looking for appealing charts, features like seamless scrolling, comprehensive coverage with good chart view management, track recording  and safety feature (MOB), Seawell marine navigation applications  are the best choice.
*** Seamless scrolling:
With Seawell chart application you can zoom in and out without having to look for and load different charts. You can still scroll/zoom even when the favorites list or track list view is open. You can also mark or add favorite spots, dynamically without going back and forth to the chart.  
*** Chart view management
Lots of care has been taken to avoid clutter of icons, to utilize the full view of the chart to display only the map. With a single ON/OFF button, you can have full chart clear view. All the buttons on the chart are configurable to be turned off from the view in the settings
