Re: charts..... download sites?
For US charts, NOAA has most navagable waterways online at the following site: <br />
http://nauticalcharts.noaa.gov/mcd/enc/index.htm <br /><br />You will need an ENC viewer. I've been using Fugawi View ENC which is freeware. The freeware viewer doesn't support printing, but you can use "Shift" - "Print Screen" to copy a screen shot to the clipboard and then paste it into an image program (just watch you keep the zoom scale the same if you are going to print a sequence of maps).<br /><br />The charts are a little slow to draw on my Celeron 900, but have a great deal of detail once used to the interface. For those into cartography, they are actually a GIS product such that each map feature (bouy, bridge, etc...) can be coded to additional info. For some of the river sets, you can click on a bridge and call up a JPG photo of the bridge taken from the water.<br /><br />I've also found charts for the Tennessee/Cumberland river systems at <br />
