Version 7.27 with latest Navionics security update and improved route and waypoint library

Compatible with Windows 8, 10 and 11

With increasing volumes of data added to charts by Navionics there are occasional instances of a small areas of loss of detail.  If this is observed, it can be solved by identifying a chart listed on the Open Chart dialogue that is not needed on the intended passage.  Using File Explorer (look for ProgramData) and moving the file to a temporary location (it can be put back later) usually enables the remaining chart files to be displayed in detail.
Version 7.28 due out soon is designed to simplify this issue.
