You remember that tufting experiment on Ilvy last summer? Those telltales, spread all over the sail, definitely helped a lot - though I could only see the lee side telltales of the sun was on the right side. Sewing in some telltale windows would help here, but then we are talking about some fancy-schmancy regatta stuff :-D

You don't need to sow the telltale windows. It would be easy to glue them with some appropriate glue. The efforts in the material is very small.

I used some 25mm wide 3M 927 glue film to assemble Mingming's wing rear part. I used Tyvex and it's not a material that is known for it's gluable performance. 

I tested with a 10 cm join and it hold 60 kg before it broke. It was not the glue that failed but the surface of the Tyvex.

Arne,

You are right, Ilvy's mast is a good cruising mast! That's what I wanted and what I designed it to be. I'm glad it worked out so well. Nevertheless, I simply find it interesting to understand the phaenomena behind her performance - which doesn't necessarily mean I want to change the rig ;-)

I really pushed Ilvy's rig to some limits, at least to the limits which are available to put her to. Two weeks ago, she hit 8.1 kn on a beam reach, that's about 2 kn above hull speed. It felt like she really wanted to take off and glide away, if it was'nt for her weight and round belly. The battens were bending a bit, but nothing to be afraid of. The mast was bending a bit, but still within what I consider safe. Of course that was flat sea conditions - I do not claim to have any serious offshore experience, and simply am not able to test her in those conditions.
