With two adults you should be fine up to 15 knots. I wouldn't go over that until you are very comfortable with the boat(righting). I've been out on the 5.2 in winds just over 20 knots and it is absolute insanity. I don't sail solo over 10 knots without other boats in the area. Even with crew, I don't go out in anything over 18-20 knots. I don't want to break anything, including myself. My favorite conditions are 8-10 knots singlehanded. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
