RASTER CHARTS VS. VECTOR CHARTS

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

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.

These RNC Charts differ from vector charts in that each chart covers a specific area, just as paper nautical charts do. 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 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. iSailGPS is priced to make it readily available to all sailors.


DEVICE REQUIREMENTS

● No device requires a cellular data plan to use iSailGPS

● iPad 2 or later with WiFi+cellular, & iPhone 4 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 & record tracks. View charts using the iOS device alone

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

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.
