I have Offshore Navigator Lite v5.08 purchased in 2013 for the Great Loop. Now I would like an update and include offshore from Maine to Florida. Could you let me know what I need to do?
To be able to use the maps for the regions you have mentioned, a purchase needs to be completed. Access the software section on the official website, then input Maine and Florida and the website will display all the maps updates for the regions specified. There are 3 results for each search and the standard price for a map region is ~22 $.

Note: The search field is on the right.
