RASTER CHARTS VS. VECTOR CHARTS

The National Oceanic & Atmospheric Administration provides both RNC (raster) & ENC (vector) charts.

The great advantage of the high resolution RNC charts used by iSailGPS is the high level of detail produced by professional cartographers that is unobtainable on any vector-based chart. ENC Vector Charts only show a coastline, water depth, navigation aids & minimal details.

These RNC Charts differ from vector charts in that each chart covers a specific area, just as paper nautical charts do. Switches automatically to a new chart when your boat leaves 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 have multiple panels, each showing a different area or scale. Each digital panel is individually displayed by iSailGPS with a north-up orientation.

Other more expensive marine software uses these same RNC charts. iSail GPS is priced to make it readily available to all boating enthusiasts.

DEVICE REQUIREMENTS

Use iSailGPS on any iOS device even if you dont have a cellular data plan for it. iPhones & WiFi+cellular iPads support full navigation. For WiFi-only iPads & iPod touch, an iOS-compatible external GPS receiver is required to show your location on the water & record tracks. However, you can view charts using the iOS device alone.

Pros and cons of iSailGPS : NOAA USA RNC Charts app for iPhone and iPad

iSailGPS : NOAA USA RNC Charts app good for

I purchased both iSail and iHike apps this year and they are both TERRIFIC! They were easy to download and easy to used. I sailed both offshore and inside small harbors in New England and found the iSail app to be incredibly useful. I chartered a sailboat this year and the chartplotter mounted on the boat was old and lacked detail. I found the iSail app especially useful when going in and out of small harbors, which required knowing precisely where I was relative to the shallow areas, which I needed to stay away from. It was no problem holding my iphone while steering the boat. I still brought hard copy maps and used the boats compass, but this app greatly enhanced my ability to safely navigate, especially in tight places. iHike performed just as well when I went horseback riding on 80 miles of unmarked trails in Colorado in a area that was "off the grid" (I gave a separate review on the iHike site). Thanks for making such great apps!

I use this app every time I sail. It is accurate, has many great options and has a very detailed help section. I reported a minor issue and a new version with the fix was released within a few days.

Some bad moments

We thought this would be a good app as we seen good reviews.....does not work for Canadian waters......did not even get to try.....waste of money for us

Can only get very large scale maps for Canadian waters. Dont buy for Canada

There are no maps for the Tennessee River, I want my money back.

This app seems to consume the processor, as zooming in / out and moving the map around takes several seconds to respond, and battery life is short when its running. It was the only app I could find to show GPS position on a NOAA chart, but it really needs work to make it more responsive.

Save your money!!! The writers of the software took photos of the nav charts. What is worse is that some such as Everglades City area, were not taken directly above chart. Also when the chart has panels the match lines have spaces..... You get what you pay for! Cheapo software.

Accessing the charts is quick and easy. Amateur sailors such as myself will find this to be the perfect app. While it has tracks and waypoints, its not bloated with extra bells and whistles that would only confuse me. For me, all those fancy do-dahs only hinder my experience. These charts are the real deal, just like the paper charts only on my iphone. The price is great too. Highly recommended.
