Don't forget that big sails create also a lot of drag.
It was really funny to see "small" Taty chasing the "big" guys with a sail that looked ridiculous small compared to the other sails. And what a speed. And jeezes, that guy can gybe. At a certain moment I remember him passing two guys with an inside gybe. Also there the smaller sail has the advantage of course. Wonderful to see. I really enjoyed it !
Didn't know he was on a 87. It were of course his conditions. Moderate offshore wind. I wonder if he can still pull it off in higher winds with much more chop.
