Honestly now, when is the last time you updated your chart card?
Trust me on this, if you can't remember, then it's well past time!
Did you know that the U.S. Coast Guard issues a Local Notice to Mariners which details changes to the buoy & light system, hazards to navigation and other marine safety issues and that this vital safety update occurs WEEKLY?
So if we're talking years since your last update you can see why it's beneficial for you to get this done!
Fortunately, Navionics is offering a killer deal on it's wonderful Platinum+ Marine Charts. Platinum cards offer extraordinary viewing options: 3D View, satellite overlay, and panoramic pictures that enhance any boating experience.
