This is the track of our sail up to Cape Greco, recorded in iSailor. ISailor is a brilliant iPad app for navigation. I first downloaded it a few weeks back but found it intuitive and easy to use.
The sail was great. We were sailing at between six and seven knots most of the way in about 10-13 knots of wind. We had our large asymmetric up plus mainsail and mizzen sail. The sea conditions we excellent and it was a really enjoyable sail.
You can see that the normal logging is nothing like as accurate!
