RASTER CHARTS VS. VECTOR CHARTS
Our government's National Oceanic and 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 originally produced by professional cartographers that is unobtainable on any vector-based chart. Each is a digital image produced by NOAA from their paper charts.
These Raster Nautical 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 and areas of coverage.
Paper charts can contain multiple panels, with each one showing a different area, scale or orientation. Each digital panel is individually displayed by iSailGPS with a north-up orientation.
Other marine software, which costs far more than iSailGPS, uses these identical RNC charts. iSailGPS is priced to make it readily available to all sailors.
● Support all functions in iSailGPS: iPhone 5s, 5c, 5, 4S, 4 & 3GS, and all cellular+WiFi iPads
● The iPod touch and the WiFi-only iPads require an iOS-compatible external GPS receiver to access all features. You can view charts using the iOS device by itself
● Not Supported: the iPhone 3G, the original iPhone, and 1st & 2nd generation iPod touch
● Continued use of GPS running in the background can dramatically decrease battery life
● No device requires a cellular data plan to use iSailGPS

What's New in Version 4.2
• Beautiful New iOS 7 Interface.
Good and Simple
I have played with this app for some time and I really like it. NOAA charts work great and waypoints are easy to add.
Sometimes it's a bit slow to load the charts but other than that it works great.
Waste of money
Waste of money, don't buy it. Very difficult to make a new waypoint and don't change from a chart to another chart
