Chartplotter lite

I like this app. It can download raster charts, look at them and get a familear course and velocity indicator.

The iPhone gps is not as responsive as a Garmin or raytheon for getting accurate speed and course so I doubt that it will be useful for sailing. Perhaps Powerboating though.

Id prefer to use ENC charts than Raster. Perhaps later.
