I was mostly interested in pure speed around the course and it sounds like it is faster when it can foil. Assuming sailors are competent of course.
Haha, big understatement about competency. I have capsized more in the first 3 months of owning a Moth than I did in my whole 20 year sailing career combined. I think I capsized 5 times or more just getting out of the marina the first day and that was a distance of 100m.
