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.

Latest version iSailGPS : NOAA USA RNC Charts: 9.4.1

Im continually improving this app so it will be even more useful! This version is updated for iOS 17.

Whats new in iSailGPS when compared with other available NOAA chart apps?

• You dont just see waypoints and routes displayed on the chart, you can actually do real great circle navigation to those waypoints and along those routes. You get information such as Estimated Time of Arrival, current bearing and heading, and remaining distance to your intermediate and final destinations.

• You dont just see individual charts. Whenever the map projection is compatible (which it is most cases), you can see adjacent charts with their margins removed stitched together seamlessly, even when the chart scales are different. For example you can see the approach chart and the corresponding harbor detail chart both together on the same screen.

• You can create, import, edit, export, and navigate both on routes based on a recorded or imported path, and on routes based on a series of waypoints.

• iSailGPSs code size is kept very small by efficient programming so in an emergency, you can download it easily even over a weak cell connection.

• The current version of iSailGPS runs on the latest devices and also on older devices with older versions of iOS , all the way back to devices such as the iPhone 6.

• There is never any confusion over what charts you have available offline. They are clearly listed by NOAA chart name and number, and shown on an overview map.

• Check the App Privacy section. We dont know who you are when you are using iSailGPS. We never send your current location or your recorded track to our servers. Hence we cannot and dont use your location data. We cannot and dont provide your location data to anyone else. Unlike other mapping apps that profit from using your location data in ways that do not keep it private, iSailGPS maintains the highest level of data confidentially.

Canada?

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

Terrible

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

Doesnt work for me

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

Server problems

Constantly fails when downloading charts. Do not buy!

Great apps!

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!

Excellent navigation app!

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.

Not recommended

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.
