Only soloing 2 sails the UNI main and the hooter. Are you describing apparent wind. I have never gone past 90 apparent and it appears the hooter will not go that deep. Just trying to clarify the comments.

Sailed it again yesterday, I can go to weather with the I-17 and we are very close. Had nice breeze, able to trap some and I am 240 lbs. Once we get past the windward mark I travel out and loosen the main a little to a beam broad reach and unfurl the hooter, the boat goes well but it can not go as deep as the I-17 with the launching kite. The boat stalls when I go deeper than about 80 degrees apparent.

Thanks for the insight, lots to learn still. Ricardo.
