Well done raster charting

iSailGPS displays raster charts - essentially photo copies of the printed NOAA charts. It shows your position. It can record your track. It can set and store waypoints (but not routes). For $8, thats a huge bargain.

There are some problems: The method for downloading charts (theyre free) is quirky. The interface has to be learned. But these are small issues compared to the utility of the app.
