USA NOAA RASTER NAUTICAL CHARTS!

Forever-free access to all USA NOAA Raster Nautical Charts, downloaded over WiFi or cell service to your iOS device. Charts from our server have a shorter download time, use less of your monthly data allotment and take up less memory on your iOS device.

Store up to 500 charts at a time to use anytime without cell service.

Switches between downloaded charts as you sail. Make wise navigation decisions on the water by choosing detailed or overview charts.

Enjoy the full resolution and what's-all-around detail of the NOAA Raster Nautical Charts (RNC). They are a welcomed advantage over ENC Vector Charts, which only show a coastline, contour lines, and minimal details.
_________________________________
TRACKS, WAYPOINTS and ROUTES!

Records a track on the chart and shows a speed graph of your trip. Choose to record a track in the background even when the iOS device is asleep or when using another App.

Mark waypoints with a convenient button on the main chart screen.

Create a waypoint by tapping a Geotagged photo.

Set a quick "Go To" waypoint or a full route and see the course, heading, bearing, direction, distance, and estimated time of arrival.

Import and Export GPX files of waypoints, routes and tracks via email or iTunes.

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 using high-resolution digital scanners.

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.

DEVICE REQUIREMENTS

Recommended: the iPhone 4S, 4 & 3GS, and all WiFi+Cellular iPads support all functions in iSailGPS.

You can view charts using the iPod Touch and the WiFi-only iPad models. These devices require an external GPS receiver to access all features.

The iPhone 3G, the original iPhone, and 1st & 2nd generation iPod Touch are not supported.

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

Customer Reviews

Great App and Great Support (5 stars)
My husband and I downloaded this app to use on a race. There was one aspect that we couldn't figure out and we had an answer to our question almost immediately via -mail.
Locator works very well. The waypoints were accurate and easy to read. We loved the fact that you could add notes so we knew if we were to make a Port or Starboard turn.
Deserves all 5 stars!!
