HOW TOS Tap Help in the app. Online Manual: isailgps.com Email developer: lwjames@isailgps.com 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. Winner of the Practical Sailor Editors’ Choice Award. Sailing becomes safer and more fun with iSailGPS!

App Reviews

  • Disappointed

    By MVGreenville
    This app does not allow you to zoom in far enough. I can understand if it was just a chart app but with GPS in your phone allowing zoom to several feet the chart should also be able to do it. Don’t waste your money.
  • Excellent support

    By sailor Wade
    I downloaded iSailGPS Yesterday, aiming to use a Dual XGPS170 Bluetooth device (not typical). Initially some confusion, but email from Larry James cleared things up right away. Support is first-rate. Love the app, but will wait for real-world experience. However, the developer is as responsive as can be. Rarely see such excellent support. Thanks Larry James!
  • Tons of individual charts you have to deal with

    By Seacurves
    Nothing about this app is easy. If you just want to measure distances or plan a multi-day trip there is just too much chart confusion.
  • Excellent App

    By buzz4rd
    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.
  • Great app. New update solves slowness updating!!!

  • Don’t waste your money

    By Len082
    Useless, doesn’t load charts , really a total waste
  • Says chart for lakes. Nope

    By Dawg1966
    I think we should be able to get our money back when the app developer misleads customers. It states clearly that there are charts for lakes. NOT for the biggest lake in the country. Lake Texoma. I know their are charts, this app just can’t access them. Buyer be ware.
  • Both Planning and at Sea

    By An Oldtime Rep
    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.
  • App hangs up

    By Kiloechooo
    Updated app on iPad. No longer works on iPhone. Hangs up during update. Delete, reinstall, won’t reinstall. But fix caused new bugsz
  • Outstanding
