iSailGPS : NOAA USA RNC Charts App Reviews

I use this app in combination with a vector chart app. The NOAA charts are much better than vector charts at displaying names of places and features. I use iSail for planning and general navigation, then switch to the vector app when going into tight places where their extra detail and course-up feature is helpful. It is a bit hard to be sure you have downloaded all the charts you will need for a cruise. It would be very helpful if the "Coastline Locator" feature would show all the NOAA charts available in one color, then the chart you have already downloaded in another.

Very reliable. Accurate. Advanced features. Great for the ipad(with gps). A bit of a battery hog in track mode so be prepared with an alt energy source.

It seems to be an OK sailing app. but I couldn’t get past the way it stitched the “paper" charts together (there seemed to be trouble at the seams, and loading the charts when I needed them, etc). I have SEAiq on also and ended up always using that instead. It’s $10 so also a good value. I wish I hadn’t have spent the money on iSail because I never use it now.

Sorry that I bought this. Slow. Unworkable map loading even on wifi!
