RASTER CHARTS VS. VECTOR CHARTS

The National Oceanic & Atmospheric Administration provides both RNC (raster) and 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 over the long run marine software uses these same RNC charts. iSail GPS is priced to make it readily available to all boating enthusiasts.

DEVICE REQUIREMENTS

No device requires a cellular data plan to use iSailGPS.

WiFi+cellular iPad 2 or later, & iPhone 4S or later support full navigation.

iPad 2 or later with WiFi-only, & iPod touch (5th gen or later) require an iOS-compatible external GPS receiver to show your location on the water and to record tracks. View charts using the iOS device alone.

Continued use of GPS running in the background can dramatically decrease battery life.

What’s New

Version 8.2.5

• Improvements to the presentation of route and downloaded chart information.
• Improvements when using an external keyboard.

What's new in iSailGPS when compared with other available NOAA chart apps?

• You don't 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 remaining distance to your intermediate and final destinations.

• You don't 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.

• You may have heard about some apps which use your location to function, but then upload that location data to a server so they can sell your location data to other individuals, advertisers and companies. We never do that, and guarantee that we won't in our privacy policy. There is no registration or subscription process, so we have no idea who you are. iSailGPS never sends your current location, your tracks, your waypoints, or your routes to our servers. You are our customer. We don't and never will have any third party data collection companies as customers. We collect nothing that would be useful to them. iSailGPS never sends any information to or receives any information from the Internet unless you specifically ask it to (for example to download a chart). Your privacy is completely safe when you use iSailGPS.

Excellent App

I’ve been using this app for about a year and I’m extremely happy with it. I can set waypoints and routes right on the app just like I would on a chart. Then follow the route, and even reverse it on my iPad or iPhone. I can send a route from my iPad to my iPhone and it brings the waypoints with it. You can take a screenshot of the route and print it out, so you can check off each waypoint as you pass it. They even added the latitude and longitude of each waypoint to the route screen. They’re very responsive and I highly recommend this app.

My favorite app

I have used many apps for marine navigation. I have settled on this beautiful app as my favorite. Did you know that it is one of the only apps in this genre that will work on the iPad1? Not only does it use NOAA charts by our gov't but it can also stitch them together.
The documentation is just excellent.
I feel that you can become a fan of this application.

An Oldtime Rep ,

Both Planning and at Sea

The charts are nicely integrated to the user interface making trip planning easy. The planned routes execute well while at sea.
My go-to app for coastal navigation.
