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 & 3GS, 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.
• GPX file sharing via AirDrop & Messages requires iOS 7.
● Continued use of GPS running in the background can dramatically decrease battery life.

What's New in Version 5.0.3
User Interface Improvements on the iPhone 6, iPhone 6 Plus and iPad.
A real navigation program worth far more than its $8.00 cost. A bit tedious loading NOAA charts, but well worth the required effort. Used on recent yacht delivery on St Johns River Florida USA with perfect results. The up to date marked charts big help. Kept me and my crew on track through somewhat complex unfamiliar waters. Prevented two near groundings. Every boater with an I phone should have this program. Perfect for small boats with no other navigation equipment. Shows "course/up" and can be used by anyone with basic boating course qualifications. I hold a US Coast Guard 100 Ton Masters License.
From the first time we used this app, we were impressed with its ease of use and clear interface. We downloaded the charts we needed with no problems. Many guest crew members have used it successfully and found it easy to interpret. We used it to navigate from New Bern, NC to the Delaware River in NJ and currently on the Chesapeake with very few problems. A great app for the price!
I will preface by saying that I have never used a charting app before so my baseline is limited. That said, I found the app very intuitive and easy to use when navigating a sailboat through some reefs while sailing from St. Croix USVI to Fajardo, Puerto Rico. I also appreciated the very prompt pre-purchase e-mail response from the app developer to a question of mine.
