I would be very nervous about sending a boat off over the horizon by itself for which I am financially responsible if it causes any damage.
There are also lots of other questions that come to mind concerning the ability for it to abide by the Rules of the Road, repair itself and other questions.
Just so the article does not mislead anyone, unstayed wing sails
are nothing new.
I think having the boat do all the work would take some of the fun out of sailing as well.
Without meaning to be too critical here, I think it is technology looking for a practical application. Very interesting stuff Scottie.
