I use polar navy: http://www.polarnavy.com/ (polar view and polar com) that support active captain data offline (don't need an internet connection, but can sync when you have one). Very handy in the Bahamas and Canada where we didn't have internet very often for example. Polar view supports raster and vector charts so I am pretty sure you can download the charts for the rivers and display active captain data on them. I paid $50 and see it is now on sale for $40 for pc. They also have iPad and iPhone apps, not sure of cost. wayne > Subject: GL: Active Caption use for the Tennessee River, Ohio River > and Upper Mississippi > Message-ID: <EBE422BE-A1E5-4D1C-92E6-B95E51B92618@aol.com> > Content-Type: text/plain; charset=us-ascii > > Hi: > > I'm using eSeaChart with the Active Captain data.
