Love it!
My wife and I have a 38 Hughes sloop and we put this app to the test this past weekend on Monterey Bay with flawless results. Get yourself a waterproof iPad case, download the charts for your area (make sure to get harbor detail charts), setup your routes in advance and youre good to go. I had just received new hard copies of local charts and those downloaded in iSail (free) were identical. While it wasnt a necessity, I tested route following from Monterey to Moss Landing via a few designated waypoints on Friday with perfect results. I then used the tracking feature to track my distance traveled under sail and average speeds during a leisurely sail on Sunday with equally perfect results. Ive also shown this app to a few other sailors who have since downloaded and are equally impressed. Thank you iSail!
