Great nav program
We have used various versions of iNavX since it was launched many years ago. We used an early version while sailing in our home waters of Alaska. We used it down through Canada and into Mexico. We used across the Pacific to Fiji and back to French Polynesia. We think that its easy to use and stitches charts seamlessly. No nav program is any better than the charts for your area. Mexico has terrible charts, US and Canada have great charts, and many South Pacific countries have so-so charts.
If your cruising area is well charted then iNavX will provide excellent navigation. Many of its features are better than our dedicated plotters so its worth owning and using.
