My vote is for OpenCPN running under Linux. I happen to use Mint 12 currently. OpenCPN works very well ie version 3.0.x. Linux mint installs somewhat like Windoz but with way fewer questions from the wizard. It is also much more stable IMHO. I have NOAA charts for the us eastern seaboard and gulf as well as world wide charts CM-93 version II for the caribbean,cuban and canadian eastcoast waters. The canadian cm-93 charts were derived from the canadian paper charts. Even the paper charts can be wrong at times. Buy a dedicated depth sounder. I use a depth sounder/fishfinder combo as it also gives a nice display of the bottom contour as well. All the charts I mentioned can be had for free on the internet as well.
