If you have a Chartbook Companion CD, consider these upgrades:

The Chartbook Companion CD includes “Offshore Navigator Lite” GPS planning and Chartplotting software. We recommend upgrading your software to Offshore Navigator. It has all the Offshore Navigator Lite features, plus Tracks, Alarms, Autopilot support and more. It only upgrades the software tools. It does not include any additional charts.

If you have a Digital ChartKit or Marine Navigator, consider upgrading to the new Chart Navigator Pro.

Chart Navigator Pro has our best GPS planning and chartplotting software along with advanced cartography and navigation data for the entire U.S. coastline. Chart Navigator Pro is $499.95 for the whole package.
