RASTER CHARTS VS. VECTOR CHARTS
The National Oceanic & Atmospheric Administration provides both RNC (raster) and ENC (vector) charts. http://www.nauticalcharts.noaa.gov/mcd/learn_diffRNC_ENC.html
The great advantage of the RNC charts used by iSailGPS is the high level of detail produced by professional cartographers that is unobtainable on any vector-based chart. Each is a digital image produced by NOAA of their paper charts.
These RNC Charts differ from computer-drawn vector charts in that each chart covers a specific area, the same way a paper nautical chart does. A new chart is switched to when traveling out of the area covered by the previous chart. For most locations, there are multiple charts at different scales with different levels of detail & areas of coverage.
Paper charts can contain multiple panels, each showing a different area or scale. Each digital panel is individually displayed by iSailGPS with a north-up orientation.
Other marine software, which costs far more than iSailGPS, uses these same RNC charts. iSailGPS is priced to make it readily available to all sailors.
● No device requires a cellular data plan to use iSailGPS.
● iPhone 6, 6 Plus, 5s, 5c, 5, 4S, 4, and all WiFi+cellular iPads support full navigation.
● iPod touch (Gen 3 or later) & WiFi-only iPads require an iOS-compatible external GPS receiver to show your location at sea & record tracks. View charts using the iOS device alone.
• File sharing via AirDrop & Messages requires iOS 7 or later.
● Continued use of GPS running in the background can dramatically decrease battery life.

I use this app when I go open water rowing.
The iPhone is in a waterproof pouch in a storage compartment of the shell( boat). After the row, my track is displayed on the beautiful noaa map.
I hope that a companion apple watch app will be offered so that the iPhone app can be controlled from the wrist.
This is a wonderful app.
