Well your right there with me, I run about 220 and my wife is about 135. Minimum weight on the Nacra 20 is 330 (if I remember correctly). We have a real good time on the 20. We've been out in wind in the mid 20's and all I can say is downhaul is your friend. We're both trying to loose weight to get as close to minimum as possible. I need to try much harder that she does. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
If you think your wife will race with you get the 20, I love mine. Tell her to get in the gym to hoist that spin. It's hard work but it's a great ride. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
