That's with about 350lbs. on the wire on the Blade.
And you had the Glaser Alter Cup mainsail (or same design) ?
As I wrote in an earlier posting. That was the only F16 on which (in my personal experience) double trapping upwind payed.
It is one reason why I value the Glaser suit of sails so highly. It seems to have struck the exact right balance between power and speed.
And you are right on the boards. I have the same experience.
