Excellent sailing app
As a professional mariner I use iSailor for double checking and recording large vessel tracks and its accuracy when comparing to professional onboard equipment its quite spot on.
Certainly would not recommend for professionals handling large vessels as a sole means of navigation, but then again, thats not the purpose of the app.
Overall its a great app for vessel tracking and recording and for the yachty or weekend navigator!
