Not sure what to make of the "wrath of wouter" exactly,
Meant nothing by it...just poking some fun at you Wouter! <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
but having sailed with both the Ullman sails and the Glaser sails I can attest that the Glaser sails (= Alter cup boats)are alot more firm in the leach and do pickup speed in the puffs better. I am really impressed by the Glaser sails. We too thought the Ullman mainsail was a bit flappy up top, probably just what you want for 1-up sailing but not to attractive in 2-up sailing.

In this shot of my boat, the leech looks great to my eye. This is on a reach in only about 7 or 8 kts. It is an Ullman (Zuccolli) sail as well. On the blade Ullman, I'd expect a similar shot to look quite pronounced with the upper leech (roach) falling off and not standing up.
It looked like the additional cloth up there on the Blade sail was what was causing the effect I was seeing. Drawing a line from the sail head board to the sail clew, you could very easily see how much more cloth there was in the Blade Roach area.
Has anyone tried different batten strengths?
Also, what about diamond tension? Perhaps John's mast was over done for the conditions, thus really lossening the leech?
I would think you'd need a way to adjust from no flapping to lots of flapping, no matter if one up or two. Having the flap in light conditions doesn't make much sense to me...but I'm not a sail designer!
