Correct both raster and vector charts are FREE in the United States. A few other countries offer free charts. We would like to support Navionics cartridges in MacENC, but we are waiting for an OS X driver for their [special] card reader. Of course keep in mind you can only use the cartridge in one device at a time so if it was in use with MacENC then your dedicated chart plotter would have no charts. Our goal has never been to make some one buy the same chart multiple times, but most chart producers believe they should be paid for every instance of use and their End User License Agreements tend to bear that out.
