MacENC is the professional solution for the mariner that wants to take the Mac aboard for real-time display of position on the vector format S-57/S-63 ENCs (Electronic Navigational Charts) AND raster format BSB and Softcharts. Plug your GPS into your Mac and watch as your vessel moves along in real-time, plotting a track behind and logging a historic position on a seamless quilted digital chart.
MacENC is right at home for planning trips and charting new destinations. A GPS is not required to work with charts. See this page for compatibilty information.
